Self-Piercing Grommets: An Introduction
Stimpson is the original manufacturer & supplier of “no hole needed” self-piercing grommets & washers for signs & banners that pierce the material and set the grommet in one single action. Self-piercing grommets & washers provide reliable hole reinforcement in signs & banners wherever they are installed. Let’s explore why sign & banner professionals rely on Stimpson self-piercing grommets & washers for their fastening needs.
What are Self-Piercing Grommets & Washers?
Unlike traditional grommet fastening systems, self-piercing grommets & washers are specially engineered to pierce the sign & banner substrate and set the grommet in one action. The interaction between the grommet and washer during the setting process safely punches a hole in the material and coils the eyelet in one stroke. Self-piercing grommets & washers work in tandem with Stimpson’s iconic 405 bench press and Stimpson’s high-quality stainless steel self-piercing die sets to set the fasteners securely and confidently.
What Are They Made From?
Manufactured from a heavier gauge, high-quality brass than traditional sheet metal fastener combinations, Stimpson self-piercing grommets & washers will withstand commercial indoor and outdoor environments for years to come. Select self-piercing grommet & washer sizes are also available in stainless steel to meet your specific application requirements. Whether your application requires brass or stainless steel fasteners, both base metals retain their attractive modern appearance after installation and instantly enhance the aesthetic of any sign or banner.
What Sizes are Self-Piercing Grommets & Washers Available In?

Are Different Finishes Available?
Stimpson offers sign & banner companies the latest in decorative finish options for self-piercing grommets. Now more than ever, end-use customers prefer to customize the grommet & washer finish, and Stimpson has you covered. Brass self-piercing grommets & washers are offered in plain brass as well as nickel and dull black oxide finishes.
Brass self-piercing grommets & washers enhance any sign or banner with their bright, lustrous golden hue finish. Since brass does not rust, brass fasteners are appropriate for both indoor & outdoor applications.
Another popular finish for signs & banners is nickel plating. This finish is known among professionals to provide a lustrous appearance and protect the fastener’s base metal. This finish provides excellent corrosion and wear resistance for both indoor & outdoor applications.
Stimpson offers a non-reflective dull black matte finish for specialty sign & banner applications. Self-piercing grommets & washers featuring a dull black finish have additional corrosion and abrasion protection making them suitable for indoor and outdoor applications.
How to Install Stimpson Self-Piercing Grommets & Washers
Unlike traditional grommets & washers, Stimpson’s self-piercing grommets & washers do not require a pre-punched hole in the substrate. When using the Stimpson 405 bench press with the appropriate self-piercing die, once the lever is depressed, the substrate is pinched between the grommet’s barrel and the washer’s sharp flat edge, cutting a hole and setting the fastener in one single action instantly improving productivity. Watch the video below to learn more about this press and to see how easy it is to set self-piercing grommets & washers with the 405 bench press.
