Flanged Barrel Torx Nut 5/16"-18 x 5/8"

Part Number: 516C58-6LFINZ

This flanged barrel Torx nut is commonly used on enclosed trailer hardware where a tamper-resistant fastener is required. The solid barrel design prevents the bolt from passing completely through the nut and provides a clean finished appearance on the outside of the trailer.

These nuts are frequently used when installing trailer door hasps, cam locks, bar lock assemblies, swing handles, and other enclosed trailer hardware.

Kit Includes

  • 1 Flanged Barrel Torx Nut
