Thinkpro 6-Spline Lug Nut Socket Set 2-Piece — 41/64" & 45/64", M12x1.25/1.5, thin-wall CR-MO with reinforced collar

Thinkpro's 2-piece 6 spline lug nut socket set replaces lost wheel lock keys and removes 6-point locking lug nuts for M12x1.25 and M12x1.5 wheels.

This compact set includes two thin-wall spline sockets sized for 41/64" and 45/64" applications, designed to fit many common aftermarket wheels and universal 6-point security lug nuts. Cold-forged chrome-molybdenum construction, a welded reinforcement collar, and dual hex tails let you tackle stubborn locking nuts with hand wrenches or impact tools while protecting wheel finishes and staying durable under heavy torque.

Will these sockets remove my wheel lock key?

They are intended as replacement removal sockets for 6-spline (six-point) wheel locks. The two sizes cover small-diameter spline patterns and are compatible with many popular lock systems and aftermarket wheels, but they do not fit 5- or 7-spline or long-spiked style nuts.

• Includes 41/64" and 45/64" thin-wall spline sockets for small-diameter locks.
• Fits M12x1.25 and M12x1.5 thread wheel systems.
• Not compatible with 5-spline, 7-spline, hex-head, or long-spike lug nuts.

How does the reinforced collar reduce breakage?

Each socket has a welded double-layer reinforcement collar around the top to spread impact forces across a thicker ring instead of a single thin wall. That reinforcement lowers the chance of cracking or snapping when you use an impact driver or confront a seized lock.

• Welded double-layer collar redirects torque to a reinforced ring.
• Reduced cracking and snapping under impact compared with standard keys.
• Maintains thin-wall profile for clearance in tight lug holes.

What driver sizes and tools work with these sockets?

Each socket has a dual 6-point hex tail that accepts 21mm or 22mm wrenches without adapters, so you can use standard hand wrenches or impact drivers for removal. The cold-forged CR-MO steel and black oxide finish resist corrosion and stand up to heavy torque from both hand and impact tools.

• Dual 6-point hex tail fits 21mm and 22mm wrenches directly.
• Cold-forged chrome-molybdenum steel body for high-torque use.
• Black oxide finish helps prevent rust on sockets stored in vehicles.

How portable and accessible is the set for emergency use?

The set ships in a custom hard plastic case sized to lock each socket into place so they won't roll away in a toolbox or glove box. At 91mm (3.6in) length, both sockets reach deep, recessed lug nuts on many modern wheels, and the case is thin enough to tuck in a vehicle storage compartment for quick access.

• Custom-fit hard case secures both sockets for storage and transport.
• 91mm length reaches recessed or deep-set wheel locks.
• Compact footprint fits glove boxes, tool bags, or roadside kits.
