The VALUE COLLECTION BT-51624-625-AS is a hex-drive set screw with a soft brass tip, designed to lock or position a component against a shaft without marring the mating surface. Measuring 5/16-24 thread size and 5/8 inches in thread length, this fastener is manufactured from Grade 8 alloy steel, providing high tensile strength for demanding mechanical applications. The brass soft tip absorbs contact stress and prevents scoring on precision shafts and spindles. It is installed by maintenance technicians, machinists, and mechanical assemblers working in industrial, HVAC, and general equipment applications.
This set screw is suited for use in shaft collars, pulleys, sprockets, gears, and similar mechanical assemblies where a secure, non-marring hold is required. The 5/16-24 thread conforms to both UNC and UNF thread standards, making it compatible with a wide range of standard tap patterns used in light and heavy industrial equipment. Grade 8 alloy steel construction handles high-torque and vibration-prone environments where lower-grade fasteners may loosen or fail prematurely.
Designed as a standard-fitment set screw for shaft collars, pulleys, gears, sprockets, and other mechanical assemblies tapped to 5/16-24 UNC or UNF thread specifications.
Installation is performed using a properly sized hex key or Allen driver; never use an undersized key, as this risks rounding the socket. De-energize and lock out any rotating equipment before accessing shaft assemblies. Hand-thread the screw fully before applying final torque to ensure proper thread engagement and avoid cross-threading. Inspect the brass tip for deformation after repeated removal and reinstallation cycles, and replace the screw if the tip is significantly worn.
