Self-Piercing Grommets & Washers
“No Hole Needed” Stimpson Self-Piercing Grommets are made from heavier gauge brass than traditional sheet metal grommets and, when set with their matching washers, pierce and set in a single action without the need for a pre-punched hole.
Available in brass, they can also be furnished with a nickel or dull black chemical finish. Ideal for use with Stimpson 405A grommet setting machine.
