ARP SAE Bolt 5-Packs, 1/2-20 UNF, Stainless Steel

These high-strength ARP bolts are great for installing most accessories. The 170,000 psi tensile strength bolts are made of stainless steel with a polished, corrosion-resistant finish. All bolts are packaged in sets of 5 bolts with matching washers.

These bolts have 1/2-20 UNF fine threads with a 1 1/4" thread length on all sizes longer than 1 1/2" (sizes shorter than 1 3/4" have a fully-threaded shank). The flange head (hex or 12-point) takes a small 9/16" wrench*, but has a full-size 0.85" diameter bearing surface**. Head measures 0.45" high.

* The 9/16" wrench size matches the size on 1/2-20 jetnuts.
** Standard AN960-816 flat washers have a 0.875" OD.
