Value Collection 34103 Blind Rivet Backup Washer 1/8 in

Product Description

The VALUE COLLECTION 34103 is a round blind rivet backup washer made from plain steel, designed to distribute clamping load and reinforce the fastening surface during blind rivet installation. With an inside diameter of 0.129 inches sized for 1/8-inch rivets, an outside diameter of 0.375 inches, and a thickness of 0.06 inches, this washer seats behind the rivet mandrel pull point to prevent pull-through on softer or thinner base materials. It is installed by electricians, sheet metal workers, HVAC technicians, and general fabricators wherever additional bearing surface is needed at a blind rivet joint.

This backup washer is suited for light fabrication, panel assembly, ductwork, electrical enclosures, and general sheet metal work where a 1/8-inch blind rivet is used and the base material requires added support to avoid deformation or pull-through. The plain steel finish makes it appropriate for interior or protected applications where corrosion exposure is minimal. Sold individually as a single piece with a minimum order quantity of 250 units.

Key Features

• Sized for 1/8-inch blind rivets with a 0.129-inch inside diameter for a close fit
• 0.375-inch outside diameter distributes clamping load across a wider bearing surface
• 0.06-inch thickness provides backing support without adding significant stack height
• Plain steel construction offers solid strength for interior and protected fastening applications
• Round profile ensures uniform load distribution around the rivet shank

Compatibility

Designed as a standard backup washer for use with 1/8-inch diameter blind rivets in sheet metal, light fabrication, and panel assembly applications.

Installation Notes

Installation is performed by hand or with standard rivet tooling as part of a blind rivet assembly. Power down any associated electrical equipment before working in enclosures or panels. Ensure the washer is fully seated and flat against the back surface of the workpiece before the rivet is set. Do not substitute this washer for structural fastener components beyond its rated light-duty backup function.
