Richeer 1/2-20 Chrome Bulge Acorn Lug Nuts 20pcs — 1.89" Long, 60° Conical Seat, SCM435 Steel

Richeer 20PCS 1.89-inch chrome closed-end bulge acorn lug nuts are heavy-duty, 1/2-20 threaded aftermarket lug nuts engineered to secure wheels with a 60° conical seat while resisting corrosion.

These lug nuts are forged from SCM435 alloy steel, heat-treated and precisely machined to deliver durable clamping force and a consistent fit for many 5‑lug aftermarket wheels. Finished in a bright chrome coating, they combine protective corrosion resistance with an OEM-style acorn appearance. The set includes 20 nuts sized at 1.89 inches (48 mm) long with a 3/4 inch (19 mm) hex, designed specifically for wheels requiring a 1/2-20 thread and a 60° conical seat.

Will these lug nuts fit my vehicle and wheels?

They fit vehicles that use a 1/2-20 wheel stud thread and wheels that accept a 60° conical seat. This product is intended for aftermarket wheels; it may not be compatible with mag, ball, round seats or some OEM wheels. Check your wheel seat type and thread specification before purchasing.

• Thread: 1/2-20 standard
• Seat: 60° conical (not mag, ball, or round)
• Length: 1.89 in (48 mm); width: 22.7 mm
• Hex size: 3/4 in (19 mm)

How durable and corrosion-resistant are these lug nuts?

Richeer lug nuts are cold-forged from SCM435 steel and undergo heat treatment for improved strength and fatigue resistance. A durable chrome-type finish adds a protective barrier against rust and maintains a polished look under road conditions. Proper torqueing and periodic inspection will help maximize longevity.

• Material: SCM435 cold-forged steel
• Heat-treated for enhanced strength
• Chrome finish for corrosion resistance and appearance
• Precisely machined threads for consistent engagement

What wheel types and models are known to be compatible?

The manufacturer lists common vehicle models and model years where these lug nuts have compatible 1/2-20 studs and 60° conical seat wheels, primarily older trucks, SUVs and Jeep applications. Compatibility depends on the wheel seat type; verify wheel specifications rather than only vehicle model year for accurate fitment.

• Examples: Jeep Wrangler (1987–2018), Cherokee (1984–2013), Grand Cherokee (1992–2010, 5-lug)
• Also listed: Dodge RAM 1500 (1994–2001), Ford Mustang (1994–2014)
• Many classic Bronco and CJ model years listed where 5-lug and conical seats apply
• Best for aftermarket wheels using 60° conical seats

How should I install and maintain these lug nuts?

Install using the proper 3/4 inch socket and torque wrench, following your vehicle or wheel manufacturer’s recommended torque values. Do not use impact guns for final torque unless specified; re-check torque after initial road miles. Keep threads clean and inspect for wear or corrosion periodically.

• Tool: 3/4 in (19 mm) hex socket
• Torque: follow vehicle/wheel manufacturer specs
• Avoid using impact wrench for final torque unless approved
• Inspect and clean threads regularly

Who is this for? These Richeer lug nuts are aimed at owners of aftermarket wheels requiring a 1/2-20 thread with a 60° conical seat who want a durable, chrome-finish acorn-style nut. They suit DIY mechanics, restoration projects, and drivers of older trucks, SUVs and Jeeps listed in the compatibility notes. If your wheels use mag, ball, or round seats, or your vehicle requires OEM-specific nuts, choose a product matched to that seat type instead.
