What bolt sizes does GRIPLOK™ fit? +

GRIPLOK™ auto-adjusts to grip any bolt from 10mm to 19mm — including non-standard sizes like 13.5mm that you won't find in any standard socket set. Turn the outer collar to expand the claw range, place it on the bolt, and the claws auto-clamp to grip. One socket. Every size in range.

Will it work on stripped and rounded bolts? +

Yes — this is exactly what GRIPLOK™ was built for. Standard sockets slip on rounded bolt heads because they grip the corners, which are gone once a bolt is stripped. GRIPLOK™'s multi-claw mechanism grips the flat sides of the bolt head, giving it something to hold onto even when a standard socket just spins.

What tools is it compatible with? +

GRIPLOK™ uses a standard 3/8" drive interface and is compatible with ratchet wrenches, torque wrenches, and power drills (with the included hex adapter). If you already own any of these tools, GRIPLOK™ works with them as-is. No additional adapters to buy.

How is this different from an adjustable wrench? +

An adjustable wrench only contacts two parallel faces of a bolt and slips on rounded heads. GRIPLOK™'s six-claw design contacts all faces simultaneously, delivers full torque without slippage, auto-adjusts without manual tuning between sizes, and connects directly to any standard 3/8" drive ratchet or drill. It's a socket — not a wrench.

What's your guarantee? +

60 days, completely risk-free. Use GRIPLOK™ on every job for two full months. If it doesn't fit the bolt sizes you need, grip the way we say it does, or perform to the standard we describe — contact us for a complete refund. No questions asked. No return required. Zero risk.

Everything You Need to Know About GRIPLOK™

How to use it, what it fits, and exactly why it works.

3 Simple Steps

1. ADJUST: Turn the outer collar clockwise to expand the claw opening for larger bolts, counterclockwise to tighten for smaller bolts. Takes two seconds.

2. GRIP: Place GRIPLOK™ over the bolt head. The multi-claw mechanism auto-clamps to the bolt on contact — whether it's a clean hex, a rounded corner, or a fully stripped head.

3. DRIVE: Attach your ratchet, torque wrench, or power drill. Turn. Full torque, zero slippage. Even on rounded and stripped bolt heads.

Pro Tips

  • Start with the collar slightly wider than the bolt for easy placement
  • For stripped bolts — expand fully
  • place over the head
  • then tighten the collar
  • For power drill use — attach hex adapter first then connect GRIPLOK™
  • Works on both left-hand and right-hand thread bolts
  • Use slow speed on power drill for maximum grip on damaged bolts

Size Range

Metric sizes covered: 10mm, 11mm, 12mm, 13mm, 13.5mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm — including non-standard sizes like 13.5mm that simply don't exist in standard socket sets.

SAE compatibility: Most common SAE sizes between 3/8" and 3/4" fall within the 10–19mm range. Works on standard SAE fasteners in this range.

Stripped and rounded bolts: Grips bolt heads with damaged or missing corners using the claw side-grip mechanism. Works where standard sockets completely fail.

Common Applications

  • Automotive — brake calipers
  • lug nuts
  • suspension bolts
  • Plumbing — supply valve bolts
  • fixture hardware
  • Appliances — washing machine
  • dishwasher fasteners
  • Furniture — IKEA and flat-pack assembly hardware
  • Construction — structural hardware
  • fixtures
  • mounts

Works With Everything You Already Own

GRIPLOK™ uses a standard 3/8" drive interface — the most common socket drive size in residential and automotive toolboxes worldwide. If you have a ratchet wrench, torque wrench, or power drill, GRIPLOK™ connects to it.

Ratchet wrench: Connect directly to the 3/8" drive. Works with any standard ratchet you already own.

Power drill: Use the included hex adapter. Insert it into the drill chuck like a drill bit, then attach GRIPLOK™ to the other end. Drill-driven speed on any bolt.

Torque wrench: Connect directly to the 3/8" drive for precision torque applications. Great for lug nuts and critical fasteners.

Universal wrench: The knurled outer collar also allows hand-turning without any drive tool at all.

The Claw Mechanism

Standard sockets grip by wrapping around the corners of a hex bolt head. When those corners are rounded or stripped, there's nothing to grip — the socket spins freely.

GRIPLOK™ uses a six-claw rotary mechanism that grips the flat sides of the bolt head, not the corners. This means it works even when every corner is completely gone — because it's gripping a different surface that's still there.

The collar adjustment opens and closes the claw diameter, letting you dial in the exact grip range before placing it on the bolt. Once placed, the claws lock under load — the harder you turn, the tighter they grip.

The Result

  • Grips flat sides — not corners that strip
  • Locks tighter under higher torque loads
  • Works on hex
  • square
  • and damaged profiles
  • Auto-adjusts — no manual size matching
  • Chrome Vanadium steel construction

One Socket for Everyone Who Turns Bolts

DIY mechanics: You work on your own car, motorcycle, or truck. You need one socket that fits whatever you encounter — including the stripped bolt from the previous owner that's been sitting there for years.

Contractors and tradespeople: You can't haul a full toolbox to every job. One GRIPLOK™ in your pocket covers the range you use 90% of the time — and handles the problem bolts that used to require a trip back to the truck.

Homeowners: You're not a mechanic. You just need to fix the thing. Leaky toilet valve. Wobbly furniture. Broken appliance. GRIPLOK™ works without requiring you to know the bolt size — it figures it out for you.

Anyone with a stripped bolt problem: If you've been told you need to drill out a stuck bolt — try GRIPLOK™ first. It removes bolts that mechanics give up on.

Auto-Adjusts 10–19mm — Including Sizes That Don't Exist

The internal claw mechanism opens and closes to grip any bolt in range. Including 13.5mm — a size you won't find in any standard socket set. Turn the collar, place it on the bolt, claws lock. One tool replaces a full tray of sockets.

Bites Down on Stripped Bolts Like a Vice

Standard sockets slip off rounded bolt heads because they grip corners that no longer exist. GRIPLOK™'s claws grip the flat sides and lock under load — the harder you turn, the tighter it grips. The bolt that stopped your job in its tracks is no longer a problem.

Works With Your Ratchet, Drill, and Torque Wrench

Standard 3/8" drive fits ratchet wrenches, torque wrenches, and power drills with the included hex adapter. Whatever tool you're already holding, GRIPLOK™ connects to it. No additional adapters, no compatibility issues.

Replace a Full Socket Set With One Tool

A complete socket set is 20+ pieces, a tray to lose track of, and three minutes of rummaging for the right size on every job. GRIPLOK™ is one piece. It's always the right size. It fits in your pocket. And it handles the jobs your socket set can't touch.

Frequently Asked Questions

What bolt sizes does GRIPLOK™ actually fit? +

GRIPLOK™ auto-adjusts to grip any bolt from 10mm to 19mm, covering the most common metric sizes in automotive, household, and construction use: 10, 11, 12, 13, 13.5, 14, 15, 16, 17, 18, and 19mm — including non-standard sizes like 13.5mm that don't exist in standard socket sets. Turn the outer collar to expand or contract the claw range before placing it on the bolt.

Will it really work on stripped and rounded bolts? +

Yes — this is the primary use case GRIPLOK™ was built for. Standard sockets slip on rounded bolt heads because they grip the corners, which are gone once a bolt is stripped. GRIPLOK™'s multi-claw mechanism grips the flat sides of the bolt head, giving it something to hold onto even when the corners are completely gone. Users consistently report removing bolts that breaker bars and standard sockets failed on completely.

What tools is it compatible with? +

GRIPLOK™ uses a standard 3/8" drive interface, making it compatible with ratchet wrenches, torque wrenches, and power drills. The power drill connection uses the included hex adapter — insert it into the drill's chuck like a standard drill bit, then connect GRIPLOK™ to the other end. Works with any 3/8" drive tool you already own. No additional parts to buy.

How is it different from an adjustable wrench? +

An adjustable wrench only contacts two parallel faces of a bolt, requires manual re-adjustment between sizes, and slips on rounded heads. It also cannot connect to a ratchet or drill. GRIPLOK™'s six-claw design contacts all faces simultaneously, auto-adjusts without manual tuning, delivers full torque without slippage, and connects directly to any standard 3/8" drive tool. It's a socket — not a wrench.

Is it durable enough for heavy regular use? +

Yes. GRIPLOK™ is constructed from heat-treated Chrome Vanadium steel (Cr-V), the same material used in professional-grade hand tools. The claw mechanism is precision-machined to maintain grip geometry under high torque loads. Mechanics, contractors, and plumbers report consistent performance across months of daily use with no grip degradation.

Can I use it with a power drill? +

Yes — use the included hex adapter. Insert the hex adapter into your drill's chuck exactly like you'd insert a drill bit, tighten the chuck, then attach GRIPLOK™ to the 3/8" drive end of the adapter. This gives you drill-speed bolt removal on any bolt in the 10–19mm range. Use slow speed for maximum grip on damaged or stripped bolt heads.

Does it work on both metric and standard (SAE) bolts? +

GRIPLOK™ is sized in metric (10–19mm). It will grip SAE bolt heads that fall within this size range — most common SAE sizes between 3/8" and 3/4" fall within the 10–19mm metric range. If you work primarily with SAE fasteners, confirm your common sizes fall within that range before ordering. For most automotive and residential use, it covers what you'll encounter.

What if it doesn't work for me? +

You're backed by the 60-Day Money-Back Guarantee. Use GRIPLOK™ on every job for two full months. If it doesn't fit the bolt sizes you need, grip the way we say it does, or perform to the standard we describe — contact us for a complete refund. No questions asked. No return required. No conditions. We stand behind this completely. For 60 days, you're taking zero risk.
