Stimpson Grommets and Washers meet the latest government and commercial specifications and are supported by a full line of grommet machines.

Sheet Metal Grommets

Metal grommets can be used with plain, teeth, or neck washers.

Plain Washers

Basic reinforcement.

Teeth Washers

A firmer, tighter grasp.

Neck Washers

Reinforces the hole with two entire parts.

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.

Rolled Rim Grommets with Spur Washers

Stimpson Rolled Rim Grommets and Spur Washers interlock, their teeth grasping the material, to provide a rugged, unyielding setting.

Oblong Grommets and Washers

Stimpson Oblong Grommets and Washers are offered in brass, aluminum, zinc and stainless steel.
