Fast-Trac Air Lite XL Backer Plates Blue 5/16in Thread 96 Pack 601RB-96

When you're running fasteners under load—whether in chassis fabrication, engine bay work, or structural reinforcement—undersized washers create stress concentration points that invite failure. The Fast-Trac Air Lite XL Backer Plates distribute clamping force across a significantly larger footprint, preventing bolt pull-through on softer materials and reducing vibration loosening on critical assemblies. At 96 pieces per pack, you'll have enough coverage for full-scale builds without mid-project supply runs.

These plates feature a 5/16" thru-hole for direct compatibility with standard fastener sizing, and the vibrant blue anodizing makes them easy to spot during assembly and inspection. Built for durability under heavy loads, they're equally at home in professional fabrication shops and serious DIY garages.
