Mardarth M14x1.5 Anti-Theft Wheel Lock Lug Nuts 4-Piece Set with 5-Point Key — Chrome, 60° Cone Seat

Mardarth 4 M14x1.5 anti-theft wheel lock lug nuts are a four-piece locking set with a matching 5-point socket key designed to secure aftermarket wheels on compatible GM trucks and SUVs.

These locking lug nuts provide a physical deterrent against unauthorized wheel removal on many Chevrolet and GMC models by replacing four standard lug nuts with specially profiled, chrome-finished carbon steel locks. Built to a 14x1.5 thread pitch and supplied with a unique 5-point driver, the set balances security, corrosion resistance and straightforward installation for vehicles with compatible studs and 60° conical seats.

How do these locks protect my wheels?

The unique 5-point locking pattern prevents common sockets and wrenches from engaging the lug, reducing the risk of wheel theft compared with standard spline or hex nuts. Because only the supplied key fits the lock, removing the wheel requires that specific tool.

• Special 5-point design resists standard socket removal
• Comes with dedicated socket key to control access
• Four locks cover critical wheel attachment points
• Chrome finish adds corrosion resistance for longevity

Will these fit my Silverado, Sierra or Yukon?

They fit aftermarket wheels that accept M14x1.5 lug nuts with a 60° cone seat and where stud length does not exceed the item’s capacity. The listing targets many Chevrolet and GMC models across model years, but confirming thread pitch and seat type on your wheels is essential before purchase.

• Thread pitch: M14 x 1.5
• Seat type: 60° cone
• Check stud length—will not fit overly long studs
• Compatible with many GM trucks/SUVs listed in product details

How do I install and remove these locking lug nuts?

Installation is straightforward with standard hand tools plus the included key: thread each lock by hand, torque to manufacturer settings with the key and a torque wrench. Removal requires the supplied key and appropriate torque tool; the key supports up to 100 ft-lb for secure fastening.

• Hand-start threads to avoid cross-threading
• Use included socket key for tightening and removal
• Supportive hex drive sizes: 13/16" and 3/4"
• Rated for up to 100 ft-lb torque on the key

What materials and durability can I expect?

Constructed from carbon steel with a chrome finish, these lug locks are engineered to withstand road exposure and resist rusting under normal use. The robust construction helps protect against impact and wear, though periodic inspection is recommended in harsh climates.

• Premium carbon steel core for strength
• Chrome plating for corrosion resistance
• Designed for long-term service life with routine checks
• Not compatible if wheel caps or certain aftermarket designs interfere

Who is this for: This Mardarth four-piece M14x1.5 locking lug nut set is intended for owners of compatible Chevrolet and GMC trucks or SUVs who use aftermarket wheels with 60° cone seats and want a simple, durable anti-theft solution. It’s ideal for drivers who prefer replacing four strategic lug nuts for deterrence, installers who need a clear set with a dedicated key, and anyone seeking a chrome-finished, corrosion-resistant option—so long as thread pitch, seat type, and stud length match your vehicle’s wheels.
