SUCOSO M14x1.5 Lug Nuts 20-Piece Black, 1.5" (38.5mm) Cone-Seat Alloy with 22mm Hex

SUCOSO M14x1.5 lug nuts are a 20-piece set of one-piece black cone-seat wheel nuts sized 1.5" (38.5mm) designed to replace OEM M14x1.5 lug fittings on many modern cars and SUVs.

These lug nuts are engineered to match wheels with an M14x1.5 thread pitch and a conical seat, offering a direct replacement for a wide range of domestic and imported vehicles. Finished in black electrophoresis coating and cold-forged from high-strength alloy steel, the set aims to resist corrosion while delivering consistent thread engagement. Before ordering, confirm your factory lug bolt length and seat type to ensure compatibility and to avoid fitment issues on taller truck studs.

Which vehicles and wheels do these M14x1.5 lug nuts fit?

These lug nuts are compatible with many OEM and aftermarket wheels that use an M14x1.5 thread pitch and conical seat. They suit a variety of cars and SUVs from brands such as Chevrolet, Ford, Dodge, Jeep, Chrysler and Cadillac, but always verify wheel seat and stud length first.

• Compatible models include Cadillac CTS, Chevy Camaro, Corvette, Impala, Malibu, Dodge Charger/Challenger, Jeep Wrangler JL/Grand Cherokee/Gladiator, Ford Mustang/Edge, Chrysler 300, and select Ram 1500 years listed.

• Fits wheels with cone (tapered) seat and M14x1.5 threaded studs only.

How are these lug nuts built and finished?

Each lug nut is manufactured as a single solid piece to avoid issues associated with two-piece caps and covers. The nuts are cold-forged, CNC-processed for accurate threads and dimensions, and finished with a black electrophoresis coating for corrosion resistance.

• One-piece construction reduces chance of rusting between parts and improves durability.
• Materials: high-strength alloy steel, cold-forged.
• Surface finish: black electrophoresis coating with 72-hour salt spray testing for corrosion resistance.
• Precision hex drive: 7/8" (22mm) for hand installation.

What are the exact specifications and installation notes?

Dimensions and hardware details are important to confirm before replacement. These lug nuts measure 1.5" (38.5mm) in length with a 26mm width and use a 7/8" (22mm) hex socket. They are supplied as a 20-piece kit to cover four wheels plus spares.

• Thread pitch: M14x1.5; Length: 1.5" (38.5mm); Width: 1.03" (26mm).
• Hex size: 7/8" (22mm); Seat type: cone (tapered); Color: black.
• Quantity: 20 pieces, one-piece design for each nut.
• Installation: recommended hand-wrench torqueing; avoid using power impact wrenches to prevent thread or finish damage.

Who is this for? These lug nuts are intended for vehicle owners, mechanics, and wheel shops replacing factory M14x1.5 cone-seat nuts on cars and SUVs that accept a 1.5" nut length — especially drivers upgrading to a durable one-piece option that resists corrosion. If your vehicle uses longer studs (common on some pickup trucks) or a different seat type (ball or flat), choose a different size or design. For any fitment questions, check your wheel manual or supply your vehicle year, make and model to confirm fit before purchase.
