AUTOPTIM M14x1.5 Chrome Open-End Lug Nuts — 20-Pack, 60° Conical Seat, 3/4" Hex

A pack of 20 AUTOPTIM M14X1.5 open-end chrome lug nuts with 60° conical seats designed as direct aftermarket replacements for many Chevy, Chrysler and Dodge wheels.

These AUTOPTIM lug nuts are a purpose-built aftermarket option for owners who need M14x1.5 thread, 60° conical-seat fasteners in a polished chrome finish. Each one-piece nut is cold-forged, heat-treated and plated to resist rust while maintaining thread accuracy for a secure fit. The open-end design accommodates longer wheel studs or locking wheel bolts and the kit includes 20 nuts, enough for five wheels plus a spare or for dual-wheel installs.

Will these lug nuts fit my vehicle?

Compatibility depends on your wheel stud diameter, thread pitch and seat angle. These nuts are M14x1.5 with a 60° conical seat and 3/4" (19 mm) hex drive, commonly used on many GM and Chrysler models from the mid-2000s onward. Always verify your vehicle’s factory specifications or measure an existing nut before ordering.

• M14x1.5 thread pitch — matches cars that use this exact specification
• 60° conical seat — fits wheels that require tapered/conical seats
• 3/4" (19 mm) hex — compatible with standard lug wrenches and sockets
• Pack of 20 — covers four wheels plus spare or five-wheel setups

How durable and corrosion resistant are these lug nuts?

AUTOPTIM uses a cold-forging and heat-treating workflow, then applies a triple-chrome finish to boost corrosion resistance and surface hardness. The nuts undergo an in-house 72-hour salt-spray test that simulates extended exposure to road salts and weather, so they hold up better than untreated hardware. Proper installation and periodic inspection further extend service life.

• Cold-forged steel core — increased strength compared with stamped alternatives
• Heat-treated for toughness and reduced cracking risk
• Triple chrome plating — improved rust resistance and shine retention
• 72-hour salt-spray evaluation — quality benchmark for corrosion resistance

What are the physical dimensions and special features?

Each nut measures approximately 0.84" (21 mm) tall with an overall width near 0.9" (23 mm), and accepts a 3/4" hex tool. The open-end construction allows access to extended studs or wheel lock sockets while maintaining full thread engagement, and the one-piece design avoids issues common to multi-piece or decorative caps.

• Overall height: 0.84" (21 mm) — compact profile for most wheels
• Width: ~0.9" (23 mm) — fits standard lug openings
• Open-end design — clears longer studs and aftermarket security bolts
• One-piece construction — reduces failure points and simplifies maintenance

Who is this for? These AUTOPTIM M14X1.5 lug nuts are aimed at drivers and mechanics who need dependable, OEM-style replacement hardware for compatible Chevy, Chrysler, Dodge and other vehicles that use M14x1.5 60° conical-seat nuts. They suit owners who prefer a chrome finish for appearance, need open-end access for aftermarket locking systems or extended studs, and want corrosion-resistant, heat-treated fasteners that meet practical workshop standards. If you are unsure about fitment, measure an existing nut or consult your wheel/stud manufacturer to confirm compatibility before purchase.
