Aluminum Flat Rivet Washers with 3/16 in Hole and 1/2 in Outside Diameter, 10 Pack - Backup Washers for Rivets, Sheet Metal Repairs, Fabrication, and Fastening Applications
These aluminum flat rivet washers are designed to provide additional support and reinforcement for riveted assemblies. Featuring a 3/16 inch center hole and 1/2 inch outside diameter, they are commonly used as backup washers behind rivets to increase bearing surface and improve holding strength in thin materials. By distributing fastening forces more evenly, these washers help reduce the risk of pull-through, tearing, and material deformation.
Manufactured from lightweight, corrosion-resistant aluminum, these washers offer long-lasting performance without adding significant weight to the finished assembly. Their durable construction makes them suitable for use with sheet metal, aluminum panels, fiberglass, plastics, and other materials where additional reinforcement is beneficial. Aluminum's natural resistance to corrosion also makes these washers well suited for applications exposed to moisture and varying environmental conditions.
These flat rivet washers are widely used in automotive restoration, trailer repair, marine maintenance, aircraft projects, HVAC work, fabrication shops, and general-purpose fastening applications. They are especially useful when installing rivets in softer or thinner materials that require additional support to achieve a secure and reliable connection.
This 10-piece pack provides a practical quantity for maintenance tasks, repairs, custom fabrication projects, and equipment assembly. Whether you're strengthening existing riveted joints or creating new installations, these aluminum backup washers offer a simple and effective way to improve fastening performance and durability.
