Keep a pair of these Sonar 3/8-18 Stainless Steel Wing Nuts and Washers in your save-a-dive kit. You won't be able to secure your backplate to your tank if you lose one, and you wouldn't be the first to miss a dive for 'want of a horseshoe nail'.

The 3/8-18 threads fit the oversized Highland bolts for 7.25-inch cylinders.

The wing nuts and washers are made premium high-quality heavy-duty (316-series) stainless steel hardware specifically for use in marine diving applications.
