SUCOSO 32PCS M14x1.5 Spike Lug Nuts for Silverado — Chrome Cold-Forged Closed-End

If you want a bold, rugged look for trucks and heavy-duty SUVs while keeping fastener strength and corrosion resistance, these lug nuts are built for that balance. The new electroplated finish and cold-forged construction improve hardness and help the finish resist salt and surface wear. This kit includes 32 closed-end, 60° conical-seat spike lug nuts plus a 3/4" (19mm) hex socket tool so you can fit aftermarket wheels with M14x1.5 thread pitch.

Will these fit my Silverado or other heavy-duty trucks?

These lug nuts are specified for aftermarket wheels using an M14x1.5 thread pitch and a 60° conical seat. The product lists broad compatibility across many full-size trucks and vans commonly fitted with M14x1.5 aftermarket wheels.

• Compatible: 1999–2018 Silverado 1500HD/2500HD/3500HD.
• Also fits Sierra 2500HD/3500HD, Suburban 2500, Avalanche 2500 and similar models.
• Included hex socket: 3/4" (19mm) for manual installation.

How durable and corrosion-resistant are these lug nuts?

The nuts are made from a single-piece, cold-forged steel construction for improved rigidity and long-term durability. A revised electroplated finish significantly increases scratch resistance and has passed a 72-hour salt spray test for better protection in harsh environments.

• Cold-forged steel increases hardness and structural strength.
• Electroplated surface reduces corrosion and everyday scuffing.
• Closed-end design keeps contaminants out of the threads.

How should I install and maintain these spike lug nuts?

Installation is straightforward but designed to be completed by hand tools to avoid over-torquing and damage to the plating. The manufacturer advises using a hand wrench rather than an impact wrench and offers technical support if you encounter fitment questions.

• Use the provided 3/4" (19 mm) hex socket and a hand wrench for final torqueing.
• Avoid impact tools that can deform threads or strip plating.
• Clean threads before install; periodic inspection maintains finish and safety.
