Product Details

The ARP 643-3750 is a premium 5-piece stainless steel bolt kit featuring 12-point heads for superior torque application. These fasteners 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:

  • ARP 300 stainless steel construction for maximum strength and corrosion resistance
  • 12-point head design for precise torque application and reduced fastener rounding
  • 180,000 psi tensile strength rating exceeds Grade 8 specifications
  • Specially polished finish provides exceptional appearance and rust resistance
  • Includes matching washers for complete installation
  • Maintenance-free performance in automotive, marine, and trailer applications

ARP's premium stainless steel fasteners deliver both superior strength and corrosion resistance, making them ideal for high-performance and demanding environments where reliability and appearance matter. The 12-point head design allows for more precise wrench engagement and reduces the risk of fastener damage during installation.

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>

The experience was great thank you.

It took exactly a week for the part to be shipped because the part came directly from the supplier. But the price was the lowest around.

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.

Better prices and even better service. Will do business with again.

I highly recommend Autoplicity for any of your vehicle needs. They have some of the lowest prices on the web and super fast shipping, I absolutely will be shopping here for all my future auto needs.

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
