Value Collection 111142PR Set Screw 8-32 5/16in Grade 8

Product Description

The VALUE COLLECTION 111142PR is an 8-32 x 5/16 inch alloy steel set screw with a knurled cup point, manufactured to Grade 8 strength standards. It is driven with a 5/64 inch hex key and conforms to ASME/ANSI B18.3 and ASTM F912 specifications. Set screws of this type are used to secure components onto shafts or within housings without a protruding head. The knurled cup point bites into the mating surface to resist rotation and axial movement under load. This fastener is appropriate for mechanical assemblies encountered in HVAC equipment, pump housings, motor shafts, and related trade applications.

This set screw is suited for use in residential and light commercial mechanical systems wherever a headless, flush-mount fastener is required to lock a rotating or stationary component to a shaft. Common install scenarios include fan blade hubs, pulley retention, coupling locks, and collar setups on shafts up to the appropriate diameter for the 8-32 thread size. Installers working in HVAC, refrigeration, and mechanical trades will encounter this fastener as a standard stock item during equipment service and assembly.

Key Features

• 8-32 UNC thread for reliable engagement in standard tapped holes
• Knurled cup point grips mating shaft surfaces to resist loosening under vibration
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 5/64 inch hex drive for use with standard hex keys and L-wrenches
• Conforms to ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless profile allows fully flush or recessed installation

Compatibility

Designed as a standard 8-32 UNC set screw suitable for any tapped hole or threaded insert conforming to the 8-32 thread specification where a knurled cup point and Grade 8 alloy steel are required.

Installation Notes

Installation is performed by a qualified mechanic or trade technician using a 5/64 inch hex key or L-wrench. De-energize and lock out all equipment before accessing any rotating components or internal mechanical assemblies. Verify that the mating shaft or bore surface is clean and free of debris before seating the cup point. Do not exceed the rated torque range appropriate for an 8-32 Grade 8 fastener as specified in applicable mechanical standards.
