The bolts, nuts and washers included with these kits are all made of stainless steel. The 5/16-18 all-thread headless bolts provide the option to adjust their bolt height.

Depending on the backplate brand and model, it is possible to have too many threads protruding causing the bolts to abrade and eventually puncture a dry suit or wetsuit. These "headless" bolts allow you to precisely adjust the bolt height to perfectly fit any brand or size of backplate and wing assembly.

This bolt kit is suitable for 5.5-inch, 7.25-inch and 8-inch diameter cylinders.

The total length of each bolt is 5.75 inches long.
