M8 Basic Bolt Kit

This kit is useful for floating and non-floating idler mounts. The jam nuts are very useful for locking in an idler bolt without spacing the idler too far outboard. It includes: M8 x 50 short threads (20mm smooth plus 12.5mm threads) Qty 1 M8 x 60 short thread (30mm smooth plus 12.5mm threads) Qty 1 M8 x 75 short thread (45mm smooth plus 12.5mm threads) Qty 1 M8 Jam nut (4mm thick nut) Qty 2 M8 Nylock Nut Qty 2 M8 Washer Qty 4 Note that the bolts are all 8mm Socket Head Cap Screws (Allen head bolts) with 6mm Allen sockets. For an 8mm Socket head Cap Screw of a given length, it starts with 30mm of threaded with the rest smooth. We cut the bolt and shorten the threads because most idler mounts (including ours) only have room for about 14mm of thread. If you want uncut bolts, let us know. We carry 8mm bolts up to 120mm in length. Typical lead time is 10–14 business days.
