This high-strength (170,000 psi) stainless steel nut is a perfect match for ARP 7/16-20 Stainless Bolt 5-Packs (sold separately).
The 7/16-20 UNF (fine thread) nuts take a 1/2" 12-point socket, but they have a full 0.70" OD bearing surface, similar to the matching ARP 717 Series bolts. Head measures 0.432" high overall. The corrosion-resistant stainless steel has a polished finish that looks great and is easy to clean. Sold individually.
