This kit is useful for stem clamps, frame clamps, and heavy duty attachment points. It includes:
M6 x 16 Qty 4
M6 x 20 Qty 4
M6 x 25 Qty 4
M6 Nyloc Nut Qty 4
M6 Washer Qty 6
Note that all the bolts are 6mm Socket Head Cap Screws (Allen head bolts) with 5mm Allen sockets.
I purchased the 1" clamp & 6mm bolt set to attach my throttle to my Terratrike Versabars. They worked great and fit perfectly.
