Wheel Accessories Parts M14x1.50 Spline Lug Nuts 20pc Black 1.50" Short 6-Spline Conical

These are a 20-piece set of M14x1.50, 1.50" long, 6-spline hex short truck-style lug nuts with a 60° conical seat and black finish, made for aftermarket wheels.

If you’re replacing or upgrading the lug nuts on aftermarket wheels, these Wheel Accessories Parts spline lug nuts provide factory-spec threading and a compact profile engineered to clear most aftermarket designs. Built from heat-treated carbon steel with a multi-layer black coating, the set is supplied as twenty pieces to cover a full four-wheel installation and matches the M14x1.50 thread pitch used on many modern domestic vehicles.

Will these lug nuts fit my vehicle and aftermarket wheels?

They are manufactured to M14x1.50 thread dimensions and a 60° conical seat, so compatibility depends on both your vehicle’s stud thread and the seat type of the wheel. Always verify your vehicle uses M14x1.50 studs and that your aftermarket wheels accept conical-seat lug nuts before ordering.

• Thread size: M14 x 1.50
• Seat type: 60° conical (tapered) seat
• Length: 1.50 inches overall
• Design intent: aftermarket wheels with conical seat fitment

How durable and corrosion-resistant are these lug nuts?

These lug nuts are cold-forged from carbon steel and heat-treated for strength, then finished with a multi-layer black coating tested to resist corrosion. The coating has been subjected to salt-spray testing to improve longevity in wet or road-salt environments, helping preserve the appearance and function over time.

• Material: cold-forged carbon steel for toughness
• Heat-treated for improved clamping strength
• Multi-layer black finish with salt-spray protection
• Engineered to SAE standards for reliable performance

What tools and steps are needed to install these short spline lug nuts?

Installation requires a matching 6-spline socket or specialized spline key plus a torque wrench to tighten to your vehicle manufacturer’s recommended torque. Because these are a two-piece spline lug design, follow standard torqueing patterns and re-check torque after initial road use for safe, even clamping.

• Required tool: 6-spline socket or spline key
• Finish tightening with a calibrated torque wrench
• Follow vehicle torque specs and wheel manufacturer guidance
• Re-check torque after 50–100 miles for added safety

Can these lug nuts work with popular Dodge, Ford, and Jeep models?

The product listing targets common domestic models that use M14x1.50 studs, but fit depends on wheel seat and stud thread. They are commonly compatible with a range of Dodge, Ford, Jeep, Chevrolet, Chrysler, Ram and other vehicles when paired with aftermarket wheels that specify a 60° conical seat.

• Example vehicles include Dodge Charger/Challenger and Ford Mustang when studs use M14x1.50
• Sized and packaged as a full 20-piece set for four wheels
• Intended for aftermarket wheels — check wheel seat type first

Who is this for: These lug nuts are a practical upgrade for owners of domestic cars and light trucks who run aftermarket wheels with conical seats and M14x1.50 studs. Ideal for DIY enthusiasts, installers, and anyone wanting a complete 20-piece black set that balances low-profile clearance, corrosion resistance, and factory-spec thread fitment. Remember to confirm thread and seat compatibility, use the proper spline socket, and follow correct torque procedures for safe installation.
