GAsupply 12x1.25 Spline Lug Nuts, Chrome 20-Pack — 1.38in Acorn with 60° Cone Seat

GAsupply 12x1.25 spline lug nuts are a 20-piece chrome acorn set with a 60° conical seat and one spline key, designed to replace factory lug nuts on compatible wheels while improving appearance and corrosion resistance.

These lug nuts are engineered for wheels with 12×1.25 studs and a 60° conical (cone) seat. Each nut is a one-piece acorn (tuner-style) design, 1.38 inches (35 mm) tall, with a six-spline drive pattern requiring the included spline key to install or remove. The polished chrome finish is electroplated in multiple layers and treated for rust resistance, making the set suitable for street use where style and longevity both matter.

Will these lug nuts fit my vehicle and wheels?

They fit only wheels and studs that specify 12×1.25 thread pitch and a 60° cone seat. Measure your existing lug nuts or consult your owner's manual to confirm compatibility before ordering. Using the wrong thread or seat type can damage studs or wheels.

• Thread pitch: 12×1.25 (metric)
• Seat type: conical/60° cone
• Nut height: 1.38 in (35 mm) acorn/tuner style
• Includes: 20 lug nuts + 1 spline key tool

How do these spline lug nuts install and remove?

Installation and removal require the included spline key because the nuts have a spline-drive outer profile rather than a conventional hex. Fit the key over the splines, then use a compatible socket or wrench on the key to torque the nut. Tighten to your vehicle manufacturer's specified torque with a torque wrench for safe, reliable contact between the cone seat and wheel.

• Use the supplied spline key for drive engagement
• Apply vehicle-specified torque with a torque wrench
• Confirm seat alignment before final tightening
• Do not reuse damaged lug nuts or studs

What materials and corrosion protection do these lug nuts offer?

GAsupply lug nuts are cold-headed from high-quality steel and plated with four layers of chrome-like finish. The plating process plus an anti-rust oil treatment gives extended resistance to salt spray and road contaminants compared with uncoated steel. They are built for street use where resistances to rust and finish fading are important.

• Construction: one-piece high-strength steel
• Finish: multi-layer electroplating for shine and protection
• Corrosion test: extended salt-spray resistance
• Pre-treated with anti-rust oil

How will these lug nuts change the look and maintenance of my wheels?

The acorn tuner profile adds a clean, finished appearance that covers studs and wheel surfaces for a tidy wheel face. Chrome plating keeps them reflective and easy to wipe clean; regular washing and periodic inspection will maintain both appearance and safety. Because they are one-piece steel, they are more durable than thin decorative caps.

• Style: polished acorn/tuner look hides exposed studs
• Maintenance: wipe-clean finish and routine inspections
• Durability: solid one-piece construction
• Packaging: premium box for storage and transport

Who is this for: These lug nuts suit car and light-truck owners who need a 12×1.25 thread with a 60° cone seat and want a durable, attractive replacement set. They are ideal for drivers upgrading from worn factory nuts, installing aftermarket wheels that accept conical seats, or anyone who prefers the cleaner look of acorn lug nuts plus the security and convenience of a spline key. Always verify fitment and follow proper torque procedures during installation.
