Product Details

The ARP 7123500 is a premium 5-piece fine thread 12-point bolt kit designed for high-performance automotive, marine, and trailer applications. These fasteners are manufactured from specially alloyed ARP 300 stainless steel, delivering exceptional strength and corrosion resistance for critical installations.

Key Features:

  • Nominally rated at 180,000 psi tensile strength for superior clamping force
  • 12-point head design for precise torque application and easier installation
  • ARP 300 stainless steel construction resists rust and corrosion
  • Specially polished finish provides professional appearance
  • Fine thread pattern for maximum thread engagement
  • Includes matching washers for complete installation
  • Maintenance-free design eliminates need for anti-seize or coating

ARP fasteners provide a substantial safety margin over standard Grade 8 hardware, making them ideal for engine builds, suspension upgrades, drivetrain assemblies, and other critical fastening applications where reliability and strength are paramount.

Best price around. Great Communication. Fast shipping. What else can I ask for?<br>I have already purchased again from them.

Best pricing I found anywhere on the part I needed, quick shipping, no hassle. Definitely going to be a repeat customer.

Very fast shipping, lowest prices on the web.

Processed and shipped fast. I was a little upset with them shipping my Eibach springs in the Eibach box, and not repackaging it. Everyone could see the box, and knew what was in it. But this will not stop me from ordering again.

Great prices and fast shipping. I had a question about the product and the had all the answers. I would definitely shop here again.
