Spur grommets are not as strong as sewn rings, but they are much more quickly installed. Do not confuse these grommets with the common washer grommets that are sold in hardware stores everywhere. Spur grommets are of heavier metal with spurs all around the inside rim of the washer that lock into a rolled edge on the barrel/eyelet part of the grommet. As a result, they will not easily pull out of the fabric.

These grommets are made of brass. Brass is more corrosion resistant than stainless steel. However, if you need grommets for high-stress, load-bearing applications, use stainless steel spur grommets. #5 5/8" grommets have a hole appropriate for a 5/8" rope to easily pass through. Hole diameter after installation is 0.625".

They will work with a minimum material thickness of 0.096" (or four layers of marine grade acrylic fabric) and a maximum material thickness of 0.264" (or 11 layers of marine grade acrylic fabric).

Note: Spur grommets cannot be installed with common washer grommet tools. Use a #5 die with a #5 spur grommet.
