Product Details

The ARP 660-1003 is a premium quality metric hex bolt kit featuring heat-treated 8740 chrome moly construction with a corrosion-resistant black oxide finish. These fasteners are nominally rated at 180,000 psi tensile strength, providing a substantial extra margin of safety over standard Grade 8 hardware for critical automotive, marine, and trailer applications.

Key Features:

  • Heat-treated 8740 chrome moly steel construction for superior strength and durability
  • Black oxide finish provides corrosion resistance and professional appearance
  • 180,000 psi tensile strength rating exceeds Grade 8 specifications
  • Metric M8 x 1.25 thread pitch, 40mm length
  • Includes 5 bolts and washers per kit
  • Hex head design for easy installation with standard tools

ARP's specially alloyed fasteners are engineered for enthusiasts who demand the highest quality hardware for engine builds, suspension upgrades, chassis modifications, and other critical applications where fastener failure is not an option. Each bolt is precision-manufactured to exacting tolerances and heat-treated for optimal strength characteristics.

Extremely Happy! Best price on the web, easy order tracking, if only all online orders from other sources were this easy. I ordered a component from another online retailer who showed parts "in stock" only to see my status as "sent to warehouse" and it was weeks. When Autoplicity shows "in stock" it really was and delivered right away.

Lowest price that i could find,fast shipping!!!!!<br>

Great service! I will def order more from these guys!

I just received my order 7260 very quickly and it was as I had ordered............very easy to order and would do business with them again and I also will recommend them to others.

Perfect item, fast shipment, great communication, and the best price.

Great communication, lowest price I could find anywhere, and quick shipping with a tracking number. What more could you ask for. 2nd time dealing with them and still impressed! order# 6935
