Whether you're making outdoor curtains, repairing a tarp, creating a banner, or sewing a custom canvas project, spur grommets provide a professional finish and superior strength compared to standard grommets.
In this guide, we'll explain what spur grommets are, how they work, and why they're the preferred choice for heavy-duty fabric applications.
What Is a Spur Grommet?
A spur grommet is a two-piece metal fastener that creates a reinforced hole in fabric or other flexible materials. Unlike standard grommets, spur grommets feature a matching washer with sharp teeth, or "spurs," that grip the material during installation.
This design distributes stress more evenly across the fabric, reducing the risk of tearing or pulling out under load.
Because of their strength and durability, spur grommets are commonly used in professional canvas fabrication and outdoor applications.
How Does a Spur Grommet Work?
A spur grommet consists of two parts:
- Rolled Rim Grommet – The finished front piece with a smooth, rounded edge.
- Spur Washer – The backing washer with small teeth that lock into the fabric.
During installation, the grommet barrel rolls over the spur washer, permanently securing the fabric between the two pieces.
The result is a clean, finished appearance and a much stronger attachment point than a plain washer grommet.
Spur Grommets vs Standard Grommets
| Spur Grommets | Standard Grommets |
|---|---|
| Teeth grip the fabric | Smooth washer only |
| Superior pull-out resistance | Less holding power |
| Better for heavy fabrics | Better for light-duty projects |
| Professional finish | Basic finish |
| Ideal for repeated tension | Can loosen over time |
If your project will experience wind, tension, or frequent use, spur grommets are typically the better choice.

Why Choose Rolled Rim Spur Grommets?
Rolled rim spur grommets offer several advantages over economy-style grommets.
Stronger Hold
The spur washer bites into the fabric instead of simply compressing it, significantly improving pull-out resistance.
Cleaner Appearance
The rolled rim creates a smooth, finished edge that looks professional and helps protect the material from wear.
Longer Life
By distributing stress across multiple teeth, spur grommets reduce localized strain and help extend the life of the fabric.
Professional Results
These are the same style of grommets commonly used by canvas shops, upholstery professionals, and commercial fabricators.
Choosing the Right Material
Brass
Brass grommets offer a classic appearance and excellent corrosion resistance, making them a popular choice for canvas, upholstery, curtains, and outdoor projects.
Nickel Finish
Nickel-plated grommets provide a bright silver appearance that complements modern hardware and fabrics while maintaining excellent durability.
Installation Tips
For the best results:
- Measure carefully before cutting the hole.
- Use the correct size setting tools.
- Install on a solid work surface.
- Ensure the spur washer teeth are evenly aligned before setting.
- Apply even pressure when rolling the barrel.
A properly installed spur grommet should sit flat against the material with no loose edges or movement.
Frequently Asked Questions
Are spur grommets stronger than regular grommets?
Yes. The toothed spur washer grips the fabric and distributes the load more evenly, resulting in greater pull-out resistance.
Can spur grommets be installed at home?
Absolutely. With the proper setting tools and a solid work surface, spur grommets are suitable for both DIY and professional projects.
What fabrics work best?
Heavy canvas, duck cloth, vinyl, tarps, upholstery fabrics, and many other woven materials work exceptionally well with spur grommets.
Do spur grommets rust?
Quality brass and nickel-plated spur grommets are designed for long-lasting performance and excellent corrosion resistance when used in appropriate applications.
