Topec 8-Piece Spline Lug Nut Socket Set — Universal Wheel Lock Removal Kit, CR-MO Steel, Black-Oxide

This master set includes multiple spline sizes and diameters forged from heat-treated chrome-molybdenum steel with a black-oxide finish so you can remove aftermarket locking lug nuts without damaging wheels. It’s built as a compact solution for DIYers and professionals who need a versatile kit to handle a wide range of spline-pattern wheel locks — provided the nut type and size match the kit’s compatibility list.

How do I know if this spline key set will fit my lug nuts?

Before buying, inspect your wheel locks visually and measure their spline pattern and diameter. This kit does not work with 8-, 9-, 10-spline, spike, large truck lug nuts, star or fluted internal hex types, so confirming shape and size prevents returns.

• Verify lug nut style: externally splined, not spike or star.
• Count the splines: this kit covers 5, 6, 7 and 12 spline patterns.
• Match spline diameters: check the listed diameters against your nuts (metric and SAE included).

What tools and torque can I use with the Topec wheel lock removal set?

The sockets are designed for use with standard lug wrenches, breaker bars, or impact tools when needed, but follow tool manufacturer guidance. The thin-wall CR-MO sockets resist deformation and are optimized for removal tasks up to typical lug-torque levels — avoid excessive force beyond recommended torque limits for your vehicle.

• Use with 3/8" or 1/2" drive adapters or lug wrenches for best leverage.
• Designed to withstand common wheel-removal torque; avoid over-torquing.
• Black-oxide finish reduces glint and resists surface corrosion.

Which spline sizes and thread fittings are included in the kit?

The set contains multiple spline profiles with a range of internal diameters to engage a variety of aftermarket lug locks. It covers common passenger-car thread standards so you can match the correct socket to the nut for secure engagement and safe removal.

• 5-spline: 5/8" internal diameter socket for small spline locks.
• 6-spline: 41/64" and 45/64" sizes for mid-range spline locks.
• 7-spline: 3/4", 5/8", 11/16" options for varied 7-spline nuts.
• 12-spline: 13/16" and 11/16" sizes for denser spline patterns.

Who this is for: mechanics, mobile tire techs, weekend car enthusiasts and anyone who needs a compact, durable assortment of spline wheel-lock sockets to remove aftermarket locking lug nuts on cars and light trucks. This kit is ideal when you have externally splined wheel locks that match the included spline counts and diameters — if your vehicle uses 8-, 9-, 10-spline, star, internal fluted, spike-style, or oversized truck lug nuts, select a compatible alternative.
