Spur grommets are not as strong as sewn rings, but they are much more quickly installed. Nickel-plated brass spur grommets will work for most applications, but if you need the strongest spur grommet that will not stretch or warp in a high-load application, use Stainless Steel Spur Grommets #2 (#354211).
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 part of the grommet. As a result, they will not easily pull out of the fabric.
Note: Spur grommets cannot be installed with common washer grommet tools. Use a #2 die with a #2 spur grommet.
