Premium Stainless Steel Stud and Nut Kit (45mm)

Upgrade your vehicle's critical hardware with the Auto Racing Products 8mm x 1.25 x 45mm stud and nut kit. Designed for builders who demand precision, these stainless steel studs provide exceptional tensile strength and resistance to thermal expansion. The 45mm length is perfect for applications requiring extra thread engagement, ensuring your components stay locked in place under high-performance conditions.

Technical Specifications

  • Thread Pitch: 8mm x 1.25
  • Total Length: 45mm (1.75 inches)
  • Nut Style: 12-point head for superior torque application
  • Material: Polished stainless steel for a clean, professional look
  • Application: Universal fitment for various engine components
  • Set Includes: 16 studs and 16 matching 12-point nuts

These fasteners are not just about aesthetics; they are built for the rigors of competitive racing. The 12-point nut design provides a larger contact area for your socket, reducing the risk of rounding off heads during high-torque installations. By switching to high-quality ARP stainless hardware, you eliminate the risk of seized or broken bolts common with factory-grade fasteners. Whether you are working on a custom turbo setup or a high-compression naturally aspirated engine, these studs deliver the reliability you need. Elevate your engine bay aesthetics and performance with genuine parts from GGCRACING.
