Description:
Upgrade your wheel-installation hardware with confidence using the West Coast Accessories W27015B kit—designed for performance- minded installs, cleaner looks and proper fitment.

Why this kit matters:

• Precision-matched for wheels using 12 mm × 1.5 thread lug hardware—common in many performance and import applications.

• Spline-drive head with a 60° conical seat ensures optimal contact with the wheel and proper torque distribution, reducing the chance of rounding off lugs or damaging the wheel seat.

• Includes everything needed for a full set: 20 lug bolts (for 20 lugs, i.e., full 5-lug or 6-lug wheel patterns) plus the install socket/adapter tool.

• Built to West Coast’s durability standards: heat-treated steel, corrosion-resistant finish and engineered for repeated safe wheel removals and re-installs.

Key Features:

• Thread size: 12 mm × 1.5 (verify your vehicle/wheel stud specifications).

• Seat style: 60° conical (common for many aftermarket wheels).

• Drive style: spline-drive (requires matching socket/adapter for install).

• Included quantity: 20 lug bolts + install tool.

• Finish and material: high-strength steel with corrosion-resistant coating (for longevity).

• Ideal use-case: aftermarket wheels, custom wheel builds, upgraded vehicles where proper hardware is critical.

Fitment & Installation Notes:

• Confirm your vehicle uses 12mm × 1.5 studs AND your wheels are designed for conical-seat, spline-drive lug bolts. If your wheels use a different seat style (tapered, ball, etc.), this kit may not fit properly.

• Before install: clean all wheel seats and studs of rust, debris or lubrication to ensure correct torque and seating.

• Use a calibrated torque wrench and follow wheel manufacturer/vehicle manufacturer torque specifications. Incorrect torque may lead to loosening or wheel damage.

• Keep the install socket/tool provided in the kit saved—using the correct tool ensures the spline drive lugs are installed/removal without damage.

• For future wheel servicing, retain the receipt and specification sheet—correct hardware is often overlooked and can lead to safety issues.
