Thinkpro 6-Spline Lug Nut Socket Set, 2-Piece 41/64" & 45/64", M12x1.25/1.5, Reinforced CR-MO

This pair of sockets is designed for drivers and mechanics who need a reliable replacement for lost or worn wheel lock keys. Each socket fits a different small spline size (41/64" and 45/64") and accepts both 21mm and 22mm wrenches on the integrated hex tail. Heavy-duty materials, a welded reinforcement collar, and a fitted hard case make the set a practical solution for emergency roadside removal or routine shop work without searching for adapters.

Which lug nuts and vehicles will this set fit?

The set is made for 6-spline (6-point) lug nuts commonly found on aftermarket wheels and wheel locks. It supports both M12x1.25 and M12x1.5 thread pitches and is compatible with many popular wheel lock brands and truck and car models.

• Fits small-diameter 6-spline lug nuts: 41/64" and 45/64" socket sizes.
• Compatible with Gorilla, McGard, White Knight-style wheel lock keys.
• Works with aftermarket wheels on Jeep, GMC Sierra, Ford F-150, Chevy, Dodge Ram, Toyota, and Honda models that use 6-point spline nuts.

How is this socket set built to avoid cracking or snapping?

Thinkpro reinforces the socket mouth with a welded double-layer collar that spreads impact forces away from a thin wall. This reinforcement reduces the chance of the socket cracking under high torque, improving durability compared with standard single-wall keys.

• Welded double-layer reinforcement collar diverts impact torque across a ring.
• Cold-forged chrome-molybdenum (CR-MO) steel construction for high strength.
• Black oxide finish helps resist corrosion while maintaining grip under load.

What drivers tools and sizes will work with these sockets?

Each socket is equipped with a dual 6-point hex tail so you can use a 21mm or 22mm wrench directly—no adapter required. The 91mm (3.6 in) length reaches recessed lug nuts without contacting the wheel surface.

• Dual hex tail fits 21mm and 22mm hand wrenches or sockets.
• Thin-wall body clears tight lug hole diameters to protect wheels from scratches.
• 91mm (3.6 in) socket length to reach deep-set or recessed lug nuts.

What should I check before buying this replacement key set?

Verify your wheel lock is a 6-spline style and measure the spline diameter and wheel-lug hole to ensure fit. This set is not universal: it will not work with 5-spline, 7-spline, hex head, or long-spiked lug nuts.

• 41/64" socket: fits splines up to 18mm; wheel lug hole must be wider than 21mm (0.83").
• 45/64" socket: fits splines up to 20.5mm; wheel lug hole must be wider than 23.6mm (0.93").
• Not compatible with non-6-spline or spiked/extended lug styles.

The Thinkpro 6 spline lug nut socket set comes packed in a custom hard storage case that locks each socket in place, preventing loss and keeping the tools ready for roadside use. Backed by responsive Thinkpro after-sales support, this set is intended as a durable replacement key kit for owners of compatible aftermarket wheels and wheel lock systems.

Who is this for? This set is for vehicle owners, fleet technicians, and DIY mechanics who need a compact, rugged replacement for lost or damaged 6-spline wheel lock keys. It's especially useful if you own vehicles with small-diameter 6-point spline lug nuts or run aftermarket wheels from brands that use these wheel locks. Confirm spline count and clearances before ordering to ensure a correct fit.
