Product Details

ARP stainless steel bolts are precision-manufactured fasteners for automotive, motorcycle, marine, and powersports applications. They are a corrosion-resistant alternative to standard hardware. This makes them well suited to exposed, high-moisture, and show-quality installations.

Key Features:

  • Stainless steel construction resists rust and corrosion in harsh environments
  • Precision-machined threads give consistent fit and reliable clamping
  • Quality control reflects ARP's reputation for performance fasteners, with manufacturing done in the USA
  • Clean appearance suits engine bay dress-up, trim, covers, and accessory mounting
  • Durable design holds up to repeated service and installation

ARP is a well-known name in racing and performance fasteners. These stainless bolts suit builders and restorers who want hardware that looks good and lasts. Select the child item that matches your needed thread and length.
