XB-09407
Cap Screw
SAF-Holland

Engineered for high-strength fastening in structural and equipment mounting, this cap-style fastener delivers consistent torque transfer and clamping force across joints subjected to vibration and dynamic loads. Measuring four inches in length with a thread size listed as .63-11 in, it provides robust engagement in compatible nuts or tapped holes. VMRS 053-007-006 places it in the fastener subsystem that includes high-strength cap screws used throughout heavy-truck assemblies. In category 42597, it is categorized with other component-level screws designed for permanent or semi-permanent fixtures. Note the Prop 65 warning associated with certain finishes; handle with appropriate PPE and follow supplier safety data when installing. Practical applications include securing heavy brackets, crossmembers, and equipment housings where a long, deep engagement is required. Installation should verify thread pitch, material compatibility, and required torque to avoid over/under-tightening. The combination of length and thread size supports high clamp loads while maintaining serviceability for removal and inspection during maintenance cycles.
