Arrow WS1/8 Steel Rivet Washer 1/8 in 40-pack

Product Description

The ARROW WS1/8 is a steel rivet washer designed to distribute load when setting rivets in soft, pliable materials or in oversized and irregular holes. These washers slip over the rivet shank before setting, providing a broader bearing surface on the back side of the joint. Each pack contains 40 washers sized for 1/8-inch rivets. Installers reach for these when standard rivet clinch alone would pull through or deform the base material, making them a practical addition to any fastener kit used on light-gauge or non-rigid substrates.

Rivet washers in this size are commonly used in HVAC duct fabrication, sheet metal work, electrical enclosure assembly, and general trade applications where thin or soft panels need reinforced fastening. They are suited for residential and light commercial work wherever 1/8-inch blind rivets are used on materials such as vinyl, thin aluminum, fiberglass, rubber, or sheet goods with enlarged holes from wear or rework.

Key Features

• Sized for 1/8-inch rivets, compatible with standard rivet guns used in trade work
• Steel construction provides durable load distribution at the rivet clinch point
• Expands effective bearing surface to prevent pull-through on soft or pliable materials
• Useful for correcting oversized or irregular holes without re-drilling or patching
• 40-piece pack supports multi-point fastening jobs without running short

Compatibility

Designed for use with standard 1/8-inch rivets across general trade fastening applications involving soft, pliable, or thin-gauge materials and oversized or irregular holes.

Installation Notes

Rivet washers are installed by a mechanic, sheet metal worker, or general tradesperson before setting the rivet. Place the washer over the rivet shank on the back side of the workpiece prior to pulling the rivet with a hand or pneumatic rivet tool. Ensure the workpiece is secure and the rivet hole is clean before setting. No special tools beyond a standard rivet gun are required.
