These grommets have an extra long length which allows for them to be used with thicker assemblies. 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 around the inside rim of the washer which will lock into a rolled edge on the barrel part of the grommet. As a result, they will not easily pull out of the fabric.
These grommets are made of nickel-plated brass. This metal is more corrosion-resistant than stainless steel. However, if you need grommets for high-stress, load-bearing applications, use stainless steel spur grommets.
Please Note: Spur grommets cannot be installed with common washer grommet tools. Use a #2 spur die set with a #2 spur grommet.
