XB-2001
Cap Screw
SAF-Holland

A heavy-duty threaded fastener used to anchor components within trailer and equipment subassemblies. The indicated length is 3.75 in with a thread pitch of 5/8-11 in, defining engagement depth and thread contact area. This fastener is selected for applications demanding robust clamp force, solid shear and tensile strength, and reliable performance in outdoor, vibration-heavy environments. VMRS code 053-007-006 places it in the component family of fasteners used to secure critical assemblies, while category 42597 contextualizes its use in SAF-Holland mounting and linkage points. Installers should pair with compatible nuts or tapped holes and ensure clean, burr-free holes to achieve full engagement and uniform torque. Proper selection considers material compatibility, plating or coating for corrosion resistance, and the appropriate anti-seize strategy to facilitate future maintenance. In field service, these screws often secure frame brackets, housings, and coupling or axle components where rigidity and repeatable alignment matter. Regular inspection includes checking for thread wear, galling, or signs of over-torque that could compromise joint integrity. Replacement at recommended intervals preserves safety margins across the trailer drivetrain.
