ARP Metric Bolt 5-Packs, 12 x 1.50mm (Fine), Black Oxide

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 30mm long threaded length on all sizes longer than 30mm (sizes shorter than 35mm have a fully-threaded shank). Choose from hex head or 12-point head. Each style 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 M12 thread, which has a 1.75mm thread pitch. The 12 x 1.50mm thread is finer than the DIN standard but coarser than the JIS standard of 12 x 1.25mm. ARP does not currently offer any black oxide nuts with 12 x 1.50mm threads.
