Product Details

The ARP 642-1250 is a 5-piece bolt kit featuring premium quality fasteners designed for differential, ring and pinion, and general automotive, marine, and trailer applications. These 12-point bolts are manufactured from specially alloyed ARP 300 stainless steel with a nominal tensile strength rating of 180,000 psi, providing a substantial safety margin over standard Grade 8 hardware.

Key Features:

  • Premium ARP 300 stainless steel construction for maximum strength and corrosion resistance
  • 12-point head design for improved wrench engagement and precise torque application
  • 180,000 psi tensile strength rating exceeds Grade 8 specifications
  • Specially polished finish for superior appearance and rust resistance
  • Includes washers for complete installation
  • Maintenance-free stainless steel construction

ARP fasteners are engineered to deliver reliable performance in demanding applications where fastener failure is not an option. The stainless steel construction ensures long-term durability and eliminates concerns about corrosion, making these bolts ideal for both high-performance and daily driver vehicles, as well as marine and trailer applications where exposure to the elements is a concern.

Great price, fast shipping.

autoplicity had the part i wanted, by the brand i trust, at a price that couldn't be beat! I saved enough that i went for the 2nd day shipping. Thanks autoplicity :)

Great so far.

I ordered some floor mats for a Prius. Autoplicity was very competitive in their pricing. Not only that, they shipped quickly and had great feedback during and after I ordered. I would purchase from them again!
