Choose these washers for their adherence to strict military standards for material and construction.
18-8 stainless steel and 321 stainless steel washers have excellent corrosion resistance in most environments. They may be mildly magnetic. Passivated 18-8 stainless steel washers have added protection against oxidation and corrosion. Black-oxide 18-8 stainless steel washers have a matte-black finish.
Cadmium- and zinc yellow-chromate plated steel washers are corrosion resistant in wet environments.

Mil. Spec. Internal-Tooth Lock Washers
![](/prerenderstable/mvPRE/contents/gfx/imagecache/965/96551a790p1-b01-digitall@halfx_636923088871051646.png?ver=imagenotfound)
Choose these washers for their adherence to strict military standards for material and construction. Internal teeth dig into the screw head while the smooth outside edge won't snag objects. These washers provide greater vibration resistance than split lock washers. Use with fasteners that have small heads, such as fillister and cheese head screws.
Cadmium-plated steel washers are corrosion resistant in wet environments.
Bronze washers are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.
410 stainless steel washers have excellent wear resistance.

Fabric Grommets
Press these grommets into a hole you've already cut. They strengthen and prevent holes from fraying in tarps, covers, and curtains. They also provide a way to run rope and cable through your material. Use a cutting punch (sold separately) to create the hole, then set the grommet using either an installation punch or a press (both sold separately). Grommet trade size refers to the hole size and the size of the installation tool needed. All of these grommets can be used outdoors.
Grommets with a tooth lock washer keep material from loosening and rotating better than those with a standard washer.
Grommets that meet NASM16491 and NASM20230 adhere to military dimensional standards.
Brass grommets are strong and have good corrosion resistance. Nickel-plated brass grommets have more corrosion resistance than brass grommets.
Hammer-driven cutting punches create holes for installing grommets when you strike them with a wooden or rawhide mallet. Hammer-driven installation punches set grommets in a hole when you strike them with a wooden or rawhide mallet. Manual presses set grommets in a hole when you squeeze the adjustable pliers-grip handle. Requires a die set (sold separately).

Rolled-Rim Reinforcing Fabric Grommets
A rolled rim provides added grip while the elongated neck and teeth on the washer, also known as a spur washer, add reinforcement and reduce rotation so you can use these grommets in thick materials such as canvas. Press the grommets into a hole you've already cut. They strengthen and prevent holes from fraying in tarps, covers, and curtains. They also provide a way to run rope and cable through your material. Use a cutting punch (sold separately) to create the hole, then set the grommet using either an installation punch or a press (both sold separately).

Reinforcing Fabric Grommets
The extended neck on the washer of these grommets adds reinforcement so you can use them in thicker material such as woven fabrics. Press them into a hole you've already cut. They strengthen and prevent holes from fraying in tarps, covers, and curtains. They also provide a way to run rope and cable through your material. Use a cutting punch (sold separately) to create the hole, then set the grommet using either an installation punch or a press (both sold separately). Grommet trade size refers to the hole size and the size of the installation tool needed. All of these grommets adhere to military dimensional standards MIL-G-16491, NASM20230, and AN230. They can be used outdoors.
Brass grommets are strong and have good corrosion resistance. Nickel-plated brass grommets have more corrosion resistance than brass grommets.
Hammer-driven cutting punches create holes for installing grommets when you strike them with a wooden or rawhide mallet. Hammer-driven installation punches set grommets in a hole when you strike them with a wooden or rawhide mallet. Manual presses set grommets in a hole when you squeeze the adjustable pliers-grip handle. Requires a die set (sold separately).
