Fasteners

Choose these washers for their adherence to strict military standards for material and construction.

Water- and Steam-Resistant Plastic Washers

Low moisture absorption and good heat resistance make these washers suitable for wet and harsh environments.

Mil. Spec. Split Lock Washers

Choose these washers for their adherence to strict military standards for material and construction.

Mil. Spec. External-Tooth Lock Washers

Choose these washers for their adherence to strict military standards for material and construction.

Mil. Spec. Internal-Tooth Lock Washers

Choose these washers for their adherence to strict military standards for material and construction.

Peel-Away Layered Ring Shims

These shims are made of layers of metal bonded with adhesive. Remove layers with a utility knife until you get the thickness you need.

Black-Anodized Aluminum Unthreaded Spacers

The anodized coating on these lightweight spacers provides increased abrasion resistance over uncoated aluminum.

PEEK Unthreaded Spacers

Use PEEK spacers as an alternative to metal spacers in high-temperature, high-stress applications. They resist chemicals, wear, and moisture.

Electrical-Insulating Unthreaded Spacers

Protect components from electrical charges.

Mil. Spec. External Retaining Rings

These rings meet military specification MS 16624.

O-Rings

Oil-Resistant Mil. Spec. Buna-N O-Rings

Choose these O-rings for their adherence to strict military standards for material and construction.

Chemical-Resistant Mil. Spec.
Viton® Fluoroelastomer O-Rings

All of these O-rings meet MIL-R-83248C.

Chemical-Resistant Mil. Spec. Viton®
Fluoroelastomer O-Rings for Tube
Fittings with Straight-Thread Connection

Also known as Boss O-rings, these O-rings are for use in tube fittings with a straight-thread connection. They meet MIL-R-83248.

Chemical-Resistant
Low-Temperature Fluorosilicone O-Rings for
Tube Fittings with Straight-Thread Connection

Flexible even at temperatures as low as -80° F, these fluorosilicone O-rings will keep your fittings free from leaks. They’re often used on fuel and coolant hose because fluorosilicone resists many chemicals, including ethanol and ethylene glycol.

Chemical-Resistant Low-Temperature
Fluorosilicone O-Rings

These fluorosilicone O-rings remain flexible at temperatures as low as -80° F. They resist ethanol, ethylene glycol, and isopropyl alcohol.

Mil. Spec. Belleville Disc Springs

These springs meet MIL-W-12133.

Grommets

Push these flexible grommets into place to protect wire, cable, and cords by turning rough-edged and uneven holes into smooth, insulated holes. Commonly used in metal panels, they also damp vibration.

High-Temperature Grommets

These flexible grommets withstand temperatures of 450° F or greater, which is approximately twice as high as our standard grommets. Push them into place to protect wire, cable, and cords by turning rough-edged and uneven holes into smooth, insulated holes. Commonly used in metal panels, they also damp vibration.

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.

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.

Fabric Grommet Kits

Kits include grommets, a cutting punch, a cutting block, an installation punch, and a die set. Use them to create a way to run rope and cable through tarps, covers, and curtains.
