AUTOPTIM M14x1.5 Spline Lug Nuts 24-Piece Black Long 2" One-Piece Closed-End with Socket

AUTOPTIM M14x1.5 Spline Lug Nuts are a 24-piece set of black, one-piece, closed-end wheel nuts engineered for M14x1.5 wheels, supplied with a matching socket for installation.

These lug nuts are built to replace original equipment on many full-size trucks and SUVs. With a 2" (50 mm) length, 3/4" (19 mm) hex, 60° tapered seat and a solid one-piece construction, they combine the fitment dimensions professionals expect with corrosion-resistant finishes. The set is cold-forged, heat-treated, and zinc-coated with a black finish to resist rust and extend service life while maintaining secure thread engagement.

Will these lug nuts fit my truck or SUV?

They are manufactured to M14 x 1.5 thread standards and designed to fit many popular North American full-size models. Always confirm your vehicle’s thread pitch and seat type before purchasing to ensure compatibility.

• Thread: M14 x 1.5
• Seat: 60° tapered (conical)
• Head size: 3/4" (19 mm) hex
• Length: 2" (50 mm); width at top: 23 mm
• Listed fit examples: Chevrolet Silverado/Sierra/Yukon/Suburban, GMC Sierra/Yukon, RAM 1500, Ford F150/Expedition (see vehicle fitment details)

How do one-piece lug nuts compare with two-piece designs?

One-piece lug nuts are a single forged unit rather than a nut body with a separate cap; this reduces failure points and improves structural integrity under load. The AUTOPTIM one-piece construction is intended to minimize cracking and maintain consistent thread contact with the wheel stud.

• Single solid body resists separation and cracking
• Uniform thread engagement for reliable torque transfer
• Fewer components mean simplified installation and inspection

What corrosion protection and durability features do these lug nuts offer?

These nuts are cold-forged and heat-treated to strengthen the steel, then finished with a zinc coating and black top layer to slow oxidation. The closed-end design also helps block moisture and debris from the internal threads.

• Cold-forged, heat-treated steel for improved toughness
• Zinc plus black finish for enhanced rust resistance
• Closed-end construction prevents contamination of threads

What’s included and how do I install them safely?

The package contains 24 black long lug nuts sized for M14 x 1.5 wheels and a compatible socket for fitting. Use a calibrated torque wrench, follow the vehicle manufacturer’s torque spec and sequence, and recheck torque after initial driving to ensure safe seating.

• Contents: 24 lug nuts and one corresponding installation socket
• Recommended tools: torque wrench and socket provided or impact wrench for removal
• Installation tip: torque in a crisscross/star pattern, then re-torque after road miles

Who this is for: These AUTOPTIM lug nuts suit owners, mechanics, and fleets who need a durable, OE-sized replacement for M14 x 1.5 wheel studs on pickups and SUVs. They’re intended for anyone seeking a stronger, corrosion-resistant, one-piece nut in a longer profile for added engagement — ideal if you want dependable fitment for common Chevrolet, GMC, RAM and select Ford models. If you’re unsure about fitment, verify your vehicle’s thread pitch and tapered seat before ordering or contact customer support for guidance.
