As of October 3rd, the USPS will be raising its fees and "implement[ing] new service standards" that may delay deliveries. As proud supporters of the United States Postal Service, we will continue to use them as our main form of shipment. We will not be raising shipping and handling charges, but packages may take extra time to arrive. We urge you to call your representatives and let them know how important an affordable and accessible USPS is to us all.

M8 Basic Bolt Kit

4 reviews
SKU: SSB127.1

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 Nyloc Nut Qty 4
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.

Good basic kit.

These provided an opportunity to experiment with the idler placement and chain management.
