The VALUE COLLECTION 307144BR is a hex socket cap screw designed for high-strength fastening applications requiring precise torque control. With a 5/8-11 UNC thread size and a 3.5-inch length under head, this fastener is partially threaded and driven by a 1/2-inch hex socket. It is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance. This screw meets ASTM A574 specifications, making it suitable for demanding mechanical and structural assemblies where bolt integrity is critical. Machinists, millwrights, and maintenance technicians are the primary installers of this fastener type.
This cap screw is suited for use in heavy equipment assemblies, machine tool fixtures, jigs, and structural mechanical joints where a recessed socket drive is preferred over an external hex head. The partially threaded shank provides a bearing surface that resists shear loads, making it a common choice in bolted flanges, mounting plates, and precision mechanical housings. Applications span industrial manufacturing, maintenance and repair operations, and general fabrication environments.
Designed as a standard inch-series hex socket cap screw for use in any application requiring a 5/8-11 UNC tapped hole and ASTM A574-compliant fastening.
Installation is performed with a 1/2-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Apply thread lubricant or anti-seize compound as required by the assembly specification to achieve accurate clamp load. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards for 5/8-11 alloy steel socket cap screws.
