SKCOAUTO M14x2.0 Spline Lug Nuts 24pc for F150 — XL spline, 60° conical, closed-end solid design

SKCOAUTO M14x2.0 spline lug nuts — a 24-piece set engineered to secure aftermarket aluminum wheels on compatible F150, Expedition, and Navigator models with a 60° conical seat.

These lug nuts are designed for trucks that use XL spline-style tuner nuts and require a closed-end, duplex design for a flush appearance and corrosion resistance. Built as one-piece solid units, they avoid the common failure points of two-piece capped nuts and come fully tested for salt-spray durability. The kit contains 24 lug nuts sized specifically to fit 14mm x 2.0 threads and is intended for aftermarket wheel applications where the XL spline pattern and 60° conical seat are required.

Will these lug nuts fit my Ford F150 or Expedition?

If your vehicle uses aftermarket aluminum wheels that accept XL spline lug nuts with a 60° conical seat, this set is compatible with many Ford models from the mid-2000s. The SKCOAUTO set fits a range of trucks that accept 14mm x 2.0 thread pitch hardware.

• Compatible models: 2004–2014 F150, 2003–2014 Expedition, 2003–2014 Navigator when aftermarket wheels require XL spline nuts.
• Thread spec: M14 x 2.0 metric threads match the listed vehicles' aftermarket wheel requirements.
• Seat type: 60° conical seat for correct taper engagement with compatible wheel seats.
• Quantity: 24 pieces—sufficient for a set of four wheels plus spares.

How are these lug nuts built and how durable are they?

SKCOAUTO manufactures these lug nuts as a single solid piece rather than a two-piece capped design, reducing points of failure and improving longevity. Each nut has undergone corrosion resistance testing to resist rust in challenging environments.

• Construction: one-piece solid design avoids seam corrosion common to two-piece caps.
• Finish and testing: salt spray tested (72 hours) for improved resistance to rust and wear.
• Closed-end duplex: prevents exposure of threads to dirt and moisture for better durability.
• Quality control: manufactured to strict standards and covered by a 12-month warranty.

What are the dimensional and functional specifications?

The set is sized and shaped for tuner-style wheel applications, with dimensions chosen to balance access, appearance and proper engagement with wheel seats. These specifics help ensure correct fitment when the wheel requires XL spline lug nuts and a 60° cone.

• Thread size: M14 x 2.0 metric thread pitch.
• Overall length: 1.97 inches; width: 0.9 inches—fits many tuner wheels with extended lug depth.
• Style: XL spline tuner pattern to work with spline sockets and key tools.
• Seat angle: 60° conical for proper seating against wheel tapered pockets.

How do I install and maintain these lug nuts safely?

Use the correct spline socket or key to install and torque each lug nut to the wheel manufacturer's recommended specifications. Closed-end nuts protect threads, but regular inspection and proper torqueing remain essential for safe wheel retention.

• Installation tool: use a matching XL spline socket or key to avoid damage.
• Torque: always tighten to the vehicle or wheel manufacturer's specified torque values.
• Inspection: check lug nuts periodically for tightness and corrosion, especially after exposure to road salts.
• Replacement: replace any nut showing excessive wear or damage immediately.

Who is this for? This 24-piece SKCOAUTO M14x2.0 spline lug nut set is aimed at owners of Ford trucks and SUVs (notably F150, Expedition, Navigator from the listed years) who have fitted aftermarket aluminum wheels requiring XL spline, closed-end, 60° conical-seat lug nuts. It's a practical choice for installers, enthusiasts, and fleets that want a solid, corrosion-tested lug nut designed to replace two-piece capped styles with a more durable single-piece construction. If your wheels call for this spline and seat combination, this set provides a full-coverage supply plus spares and comes with a year-long warranty for added confidence.
