RIMKOLO Locking Lug Master Key Set — 16-Piece SAE & Metric Wheel Lock Removal Kit, Cr-Mo

RIMKOLO's 16-piece locking lug master key set is a comprehensive SAE and metric wheel lock removal kit built to extract a wide range of aftermarket and factory wheel lock lug nuts quickly and reliably.

This master key assortment groups spline, star, hex and fluted hex profiles into a single compact kit so you can remove unfamiliar or mismatched wheel locks without guessing which specialty key fits. Each key is heat-treated chrome-molybdenum (Cr-Mo) steel with a black-oxide finish for corrosion resistance and long life. The set includes double-hex heads sized to pair with common sockets and wrenches and arrives in a sturdy blow-molded case for organized storage and transport.

Which lock styles and sizes are covered by this RIMKOLO kit?

The kit covers 16 distinct key profiles across spline, star, and hex-style lug nuts to address most OEM and aftermarket lock patterns. Both SAE and metric sizes are included so you won’t need separate sets for different vehicles. Laser-etched dimensions on each key let you match fasteners quickly.

• Spline sizes: 12-spline (13/16, 11/16), 7-spline (3/4, 5/8, 11/16), 6-spline (41/64, 45/64), 5-spline (5/8)
• Star lug types: 10-point 1/2, 8-point 5/8, 8-point 7/16, 9-point 1/2
• High-tech hex: 15mm, 9/16, 12mm, fluted 12mm
• Double-hex head sizes: 13/16 and 7/8 (19 and 22mm) compatible with common sockets

How durable and reliable are the keys for heavy use?

Each key is manufactured from heat-treated chrome-molybdenum steel for strength under torque and repeated service. A black-oxide finish improves corrosion resistance and reduces galling when keys contact rusted or painted lug nuts. The materials and treatment choices aim to deliver extended life even with regular use in harsh environments.

• Heat-treated Cr-Mo construction for high tensile strength
• Black-oxide surface treatment to resist rust and wear
• Double-hex design to reduce tool slippage and improve socket compatibility

How does the double-hex design help during removal?

The double-hex heads provide two common wrench/sockets sizes on each key so you can use standard 13/16 or 7/8 (19 and 22mm) sockets without adapter workarounds. That design gives more contact area for torque transfer and reduces rounding when dealing with stubborn or damaged lock nuts. Laser-marked sizes make it straightforward to pair the key with the right tool.

• Two hex sizes per key for flexible socket choices
• Improved torque transfer and reduced slippage
• Laser-clean dimensions for fast identification

What’s included in the kit and how is it stored?

The set ships with 16 keys covering a wide array of lug styles and a heavy-duty blow-molded case to keep pieces organized and protected. The case is portable for mobile repairs or emergency roadside use and holds each key securely so you can find the right profile at a glance.

• Complete 16-piece assortment of spline, star, and hex keys
• Sturdy blow-molded storage case with labeled slots
• Compact footprint for glovebox or service trunk storage

Who this is for: The RIMKOLO 16-piece master key set is ideal for mechanics, tire shops, fleet technicians and vehicle owners who work on multiple makes and aftermarket wheels. If you frequently encounter mixed or unknown locking lug nuts — or want a single, durable kit to cover both SAE and metric sizes — this set reduces guesswork and saves time during wheel removal and repairs.
