Value Collection R63263240 Set Screw 5/16-24 X 1 in

Product Description

The VALUE COLLECTION R63263240 is a 5/16-24 cup point set screw manufactured from 18-8 stainless steel. Cup point set screws apply concentrated holding force at a single contact point, making them well suited for securing collars, pulleys, gears, and similar components onto shafts. The 5/16-24 thread designation indicates a 5/16-inch nominal diameter with a 24-thread-per-inch UNF pitch. Overall length is 1 inch. Drive is a 5/32-inch hex socket, compatible with standard hex keys and Allen-type drivers. The 18-8 stainless steel construction provides corrosion resistance suitable for general industrial and mechanical assembly applications.

This set screw is used in mechanical assemblies where a fastener must bear against a shaft or mating surface without a protruding head. Typical applications include HVAC equipment drives, fan hubs, motor shaft collars, pump couplings, and general machinery. The UNF thread form is common in American standard fastener applications. Installers working in corrosive or damp environments often specify 18-8 stainless for longevity over plain steel alternatives.

Key Features

• Cup point geometry concentrates clamping force for reliable shaft retention
• 5/16-24 UNF thread for precise engagement in standard tapped holes
• 18-8 stainless steel construction resists corrosion in humid or wet environments
• 5/32-inch hex drive accepts standard hex keys and Allen wrenches
• 1-inch overall length suits moderate-depth shaft engagement requirements
• Headless profile allows flush or recessed installation

Compatibility

Designed as a standard UNF set screw for use in any application requiring a 5/16-24 threaded headless fastener with a cup point and 5/32-inch hex drive.

Installation Notes

Set screws of this type are typically installed by machinists, millwrights, or maintenance technicians using a calibrated hex key or T-handle Allen driver sized to 5/32 inch. De-energize and lock out any rotating equipment before installing or removing set screws on shafts. Ensure the tapped hole is clean and free of debris before threading the fastener in. Do not exceed the torque rating of the stainless steel material, as over-torquing can gall or strip 18-8 threads.
