Why Upgrade to ARP Stainless Bolts?
Because rusty, rounded-off bolts are not part of a “clean build.”
ARP delivers precision-engineered fasteners that not only look better, but also provide consistent torque and long-term durability—something cheap hardware fails at regularly.
ARP stainless steel bolts are rated at 170,000 psi to provide a substantial extra margin of safety over Grade 8 and other hardware. They are to be had in hex head or 12-point styles and quite a few lengths and sizes to be used on cars, boats, trailers, and more.

Set of 5ARP started applying technology to race fastener design and manufacturing in 1968. Today’s critical diesel fasteners – head studs and bolts, main studs and bolts, and driveline – have been designed stronger than ever before to deal with the extreme loads.
Why It Matters
Low-quality bolts can lead to:
- Corrosion and seized threads
- Inconsistent torque
- Rounded heads and stripped threads
The ARP 773-1003 bolts provide reliable fastening, clean appearance, and long-term durability, making them a simple but worthwhile upgrade.
As a results, installation pre-loads – the amount the fastener is stretched right through installation – are very high.Specifications:Socket Size(s): 12mm 12ptTorque Value: 54 ft-lbs (73.2 Nm)UHL: 30mmThread Length: 30mm Grip Length: n/amm Thread Diameter-Spacing: M10 x 1.25mm Grip Diameter: 10mm Wrenching: 12mm Head Height: 9.0mm Collar Diameter: 18.5mm
