White Knight bulge acorn lug nuts 1/2-20 20-pack Chrome — 13/16" Hex, Cold-Forged Carbon Steel, Triple-Layer Finish

White Knight 1/2"-20 bulge acorn lug nuts are durable, cold-forged carbon-steel wheel fasteners designed to fit select aftermarket and factory wheels while adding a polished chrome look.

These lug nuts pair heavy-duty construction with a traditional bulge-acorn profile to provide reliable seating and an attractive finish for compatible wheels. Cold forging produces uniform threads and increased strength compared with stamped finishes, while the triple-layer chrome coating enhances corrosion resistance and wheel aesthetics. Sold in a 20-pack, these lug nuts are intended for projects where the correct thread pitch and seat type match the wheel and hub specifications.

How do these lug nuts fit my wheels and vehicle?

They are made for wheels and hubs that accept a 1/2"-20 threaded stud with a 60° conical (bulge) seating. Before you buy, compare the lug nut thread, seat angle, hex size, and overall length to your vehicle’s wheel specifications to ensure compatibility.

• Thread: 1/2"-20 standard thread pitch for many aftermarket applications
• Seat style: 60° conical (bulge/acorn) seating
• Hex: 13/16" wrench size for installation and removal
• Overall height: 1.40" and diameter ~0.90" for clearance checks

What materials and finish are used, and how do they perform?

The nuts are cold-forged from carbon steel for consistent strength and dimensional accuracy. A triple-layer chrome finish (standard or black chrome option) improves corrosion resistance and gives wheels a clean, reflective appearance without premium packaging costs.

• Material: cold-forged carbon steel for strength and uniform threads
• Finish: multi-layer chrome or black chrome for corrosion protection
• Design: hex-body bulge-acorn profile for quick, conventional socket use
• Tested: manufactured to meet common OEM and aftermarket tolerances

How should I install and maintain these lug nuts safely?

Installation requires the correct socket (13/16") and adherence to your vehicle or wheel manufacturer torque specifications. Over-tightening or using the wrong seat style risks damage to the wheel or unsafe fastening; always verify fitment and torque values before driving.

• Use a 13/16" socket or wrench for secure torque application
• Follow vehicle/wheel manufacturer torque specs to avoid overstress
• Check fitment—seat style, thread size and length—prior to installation
• Inspect periodically for corrosion or loosening; replace if damaged

Who is this for? These White Knight bulge acorn lug nuts are suitable for car and truck owners, mechanics, and wheel shops that need dependable, attractively finished fasteners for compatible aftermarket or factory wheels. They are especially useful for anyone replacing multiple lug nuts at once (20-pack) or swapping wheels where a bulge-acorn seat and 13/16" hex are standard. Because fitment varies across vehicles and wheel brands, this product is best for buyers who confirm thread pitch, seat style, and torque requirements before purchase. White Knight backs these lug nuts with a one-year manufacturer warranty; contact cs@whtknight.com for warranty or fitment questions.
