SKCOAUTO M14x1.5 Spike Lug Nuts 24-Pc Kit with Socket Key — Chrome, Cold-Forged Steel for GM 6-Lug Wheels

SKCOAUTO M14x1.5 24-piece spiked lug nut set includes a dedicated socket key and gives aftermarket 6-lug wheels a bold, finished look while matching factory fitment for many GM 1500-series SUVs and trucks.

These solid one-piece spike lug nuts are built for drivers who want to replace damaged or missing hardware or upgrade the appearance of their Silverado, Sierra, Suburban, Yukon, Avalanche, Escalade, Acadia and other 6-lug models that use 14x1.5 threads. Cold-forged, heat-treated steel and a closed-end spike design create a sturdy, corrosion-resistant fastener intended for use with aftermarket wheels that accept a 60° conical seat.

Will these lug nuts fit my vehicle and wheels?

Check both the vehicle’s stud thread and the wheel’s seat type before ordering: the SKCOAUTO set uses a 14 x 1.5 thread pitch and a 60-degree conical seat, common on many GM 6-lug trucks and SUVs. The nuts are designed for aftermarket wheels that accept closed-end, 3/4" (19mm) hex nuts.

• Thread: M14 x 1.5 (metric)
• Seat: 60° conical (tapered) seat — fits compatible wheels
• Hex size: 3/4" (19 mm) for the included socket key and standard tools
• Overall length: 4.37 inches (spike included) — verify clearance behind wheel

How durable and secure are these one-piece spike lug nuts?

Each nut is cold forged then heat treated to increase tensile strength and wear resistance, and the one-piece construction eliminates potential loosening points found in multi-piece designs. The closed-end body helps keep out dirt and moisture, which reduces corrosion risk around the stud.

• Manufacturing: cold forged and heat treated steel for high strength
• Design: one-piece solid construction prevents part separation
• Finish: chrome plating for rust resistance and easy cleaning
• Protection: closed-end form keeps contaminants away from studs

What tools and steps are needed to install these lug nuts safely?

The set includes a matching socket key for installation and removal; for final torque use a calibrated torque wrench to avoid overtightening and wheel damage. Install one wheel at a time, hand-thread each nut first, then perform a star-pattern torque sequence to the vehicle manufacturer’s recommended specification.

• Included: 1 socket key sized for 3/4" (19 mm) hex
• Recommended tool: torque wrench to vehicle factory torque spec
• Procedure: hand-thread, tighten in a star pattern, recheck after 50–100 miles
• Clearance: confirm spike length (4.37" OAL) clears wheel and brake components

What comes in the box and what warranty is offered?

Each kit ships with 24 spike lug nuts and one socket key sized to the hex head, packaged for automotive use. SKCOAUTO backs the product with a 12-month warranty covering manufacturing defects; normal wear or improper installation are typically excluded, so keep purchase details and installation records.

• Quantity: 24 lug nuts (spike style) plus 1 socket key
• Color: chrome finish included
• Seat type: conical 60°; closed-end spikes
• Warranty: 12 months from purchase against manufacturing defects

Who is this for: These SKCOAUTO M14x1.5 spike lug nuts are aimed at owners of 6-lug trucks and SUVs who need direct-fit replacement hardware for aftermarket wheels or who want a distinctive spiked look while retaining reliable, one-piece strength. Ideal for do-it-yourself installers and professional shops that require a chrome finished, closed-end nut with a 3/4" hex and a matched socket key.
