Grommet Types - Plain, Rolled Rim and Self Piercing

There are three basic type of grommets that are industry standards. These grommets are sized according to the hole size in the grommet after the grommet is set. Grommet numbers start with #00, then #0 thru #8. The larger the number the larger the hole size. For a complete list of sizes available with dimensions see our GROMMET PAGE.

Plain Grommet and Washer

Plain Grommets and Washers are the most common grommet used. The flange of the grommet is slightly domed and the edges are flat. The accompanying washer has a slight cup in it but does not have any teeth or spurs. Plain grommets can use a tooth washer for additional holding strength. These grommets are the most economical and are widely used in banners, flags and tarps.

Rolled Rim Grommet & Spur Washer

Rolled Rim Grommets and Spur Washers are heavier than regular grommets and are used in applications where maximum holding strength is needed. Rolled rim grommets and spur washers interlock with their teeth grasping the material providing a stronger setting than plain grommets. Rolled rim grommets and spur washers have their size embossed on the flange for easy identification.

Self Piercing Grommet & Washer

Self Piercing grommets are grommets that pierce your material without pre-punching a hole. The self piercing grommets use a heavier gauge metal than plain grommets and work together with a unique washer allowing the grommet to pierce and set in a single action. Just place the grommet on the top die, lay the washer on the bottom die, position your work and pierce and set in one action.
