ARP M12 x 1.50 x 50 12-Point Head Stainless Steel Bolt, 5-Pk

Brand: Automotive Racing Products (ARP)

High-strength metric 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. Pack of 5 bolts includes matching washers.

These 12 x 1.50mm (fine thread) metric bolts have a 50mm long under-head length, including the 20mm long grip (unthreaded portion). 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.
