SUCOSO M14x1.5 Open-End Lug Nuts 32-Piece Set — Silver, 60° Conical Seat, 3/4" Hex

These SUCOSO M14x1.5 open-end lug nuts are a 32-piece set engineered to replace factory lug nuts on compatible GM and truck wheels, offering durable cold‑forged steel construction with a 60° conical seat and 3/4" hex for secure, tidy installation.

When you need a full set of lug nuts for aftermarket wheels on heavy-duty GM trucks and SUVs, this SUCOSO kit supplies the right thread pitch, seat type and length to match many OEM and aftermarket applications. The set is finished in silver, designed for corrosion resistance and visual consistency, and includes 32 open-end nuts to cover dual-wheel or spare needs for some vehicles.

Will these lug nuts fit my Silverado, Sierra or Tahoe?

These lug nuts are sized specifically for wheels that accept an M14x1.5 thread pitch with a 60° conical seat and a 3/4" (19 mm) hex head. They are commonly used across a range of GM trucks and some large SUVs—confirm your wheel’s thread pitch and seat style before ordering.

• Thread pitch: M14x1.5
• Seat type: 60° conical (tapered)
• Hex: 3/4" (19 mm) for hand-tool installation
• Length: 0.83" (21 mm) — check stud engagement depth

How durable and corrosion-resistant are these lug nuts?

SUCOSO manufactures these lug nuts using cold forging to increase hardness and strength, producing a robust part built for long-term use. The silver finish helps resist rust, and the clean thread tapping reduces wear during installation and removal.

• Cold-forged high-strength steel for improved rigidity
• Clean, precise threads to minimize cross-threading risk
• Silver finish for added corrosion resistance and a neat look
• Made to withstand typical road and weather exposure for truck use

What tools and installation steps are required?

Installation is straightforward but should be done with hand tools to prevent over-torquing or damage. The open-end design means the wheel stud can extend through the nut for some aftermarket wheels; always torque to the vehicle manufacturer’s specification with a calibrated wrench.

• Use a 3/4" (19 mm) hand wrench — do not use an impact gun
• Start threads by hand to avoid cross-threading
• Tighten to vehicle-specified torque in a star pattern
• If uncertain, consult a professional installer or SUCOSO support
