Product Details

The ARP 645-4750 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, nominally rated at 180,000 psi tensile strength, 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 stripping
  • 180,000 psi tensile strength rating exceeds Grade 8 specifications
  • Polished stainless finish resists rust and corrosion
  • Maintenance-free design ideal for automotive, marine, and trailer applications
  • Includes washers for complete installation

ARP's premium fasteners are engineered for professional mechanics and enthusiasts who demand reliability and performance. The stainless steel construction ensures long-lasting durability even in harsh environments, while the precision 12-point head design allows for easy installation with standard tools.

Easy shopping

Great company to do business with! Ordered a Thule 916XTR bike rack for my car and their prices blew away everyone else on the 'net! Ordered on Sunday, they shipped on Monday and sent me a tracking number that night. Super fast shipping and great communication! I'll definitely be coming back to Autoplicity again!

Trustworthy seller. This is my second order. Got it quickly. good job!

Super fast shipping, easy to use site, would buy again from site

Order shipped 2 days after ordered <br>and hey gave me a tracking number which is cool<br>lets see hoe fast it will come

Just what you want from a merchant but don't expect; fast, courteous service and attention to the details of your order. I'm a happy consumer. Thank you, Autoplicity. I'll be back.

competitive prices and good selection. Will definitely look to this vendor when purchasing automotive parts in the future. I ordered a roof rack and it was very hard to find elsewhere and the few places I did find it, it was more expensive.. it was cheap and easy here. thanks :)

Lowest price on the Internet, good packaging and fast shipping.

Price was the lowest for the product that I wanted. That's including shipping price, which was still cheaper. Will definitely look into other products from them.
