ARP M12 x 1.50 x 25 12-Point Head Black Oxide Bolt, 5-Pack

Brand: Automotive Racing Products (ARP)

These high-strength metric ARP bolts are great for installing most accessories. The 180,000 psi tensile strength bolts are made of 8740 chrome moly with a black oxide finish. All bolts are packaged in sets of 5 bolts with matching washers.

These 12 x 1.50mm (fine thread) metric bolts have a 25mm long long fully-threaded shank. The 12-point head takes a 14mm wrench, but has a full 21.6mm bearing surface. The head measures 11.7mm tall.

Note: The fine 1.50mm thread pitch is not the same as the more common DIN standard M12x1.75 thread. The 12x1.50mm thread is finer than the DIN standard but coarser than the JIS standard of 12 x 1.25mm.
