Brand: Automotive Racing Products (ARP)

These high-quality nuts from ARP are constructed of 8740 chrome moly steel for 180,000 psi tensile strength. The black oxide finish looks great and takes paint easily.

These nuts have 10 x 1.25mm (fine) metric threads. The 12-point head takes a small 12mm socket but has an oversized 17.8mm OD bearing surface. Measures 10.2mm high overall. Sold in packs of 10 nuts.

Note: 10 x 1.25mm is a non-standard fine thread. M10 x 1.5 threads are more common in most applications.
