Value Collection 101211PR Set Screw 8-32 X 7/8 in Cup Point

Product Description

The VALUE COLLECTION 101211PR is a cup point set screw designed for mechanical assemblies where a fastener must apply clamping force without a protruding head. Threaded 8-32 UNC with an overall length of 7/8 inches, this screw is driven by a 5/64-inch hex key. It is manufactured from Grade 8 alloy steel, providing high tensile strength suitable for demanding hold-down and locking applications. Compliance with ASME/ANSI B18.3 and ASTM F912 confirms dimensional accuracy and mechanical performance. This fastener is a standard item in the inventories of machine shops, HVAC equipment assemblers, and industrial maintenance operations.

Cup point set screws of this type are used wherever a shaft, rod, or component must be locked in position within a collar, hub, gear, or pulley. The cup point geometry bites into the mating surface to resist rotation and axial movement. This size is common in light-duty mechanical drives, fan blade hubs, valve stems, and similar assemblies found in commercial and residential HVAC systems, plumbing equipment, and general industrial machinery. This item is sold individually but requires a minimum order quantity of 100 units.

Key Features

• Cup point geometry bites into mating surfaces for positive rotational and axial locking
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 8-32 UNC thread for broad compatibility with standard tapped components
• 5/64-inch hex drive accepts a standard hex key or T-handle driver
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards

Compatibility

Designed as a standard 8-32 UNC cup point set screw for use in any application requiring an ASME/ANSI B18.3-compliant headless fastener of this thread size and length.

Installation Notes

Installation requires a 5/64-inch hex key. Ensure the mating tapped hole is clean and free of debris before driving. Do not exceed the recommended seating torque for the thread size as specified by applicable mechanical codes or equipment manufacturer guidelines. Avoid overtightening, which can strip the hex socket or damage the mating shaft surface.
