Value Collection MP40471 Set Screw 10-32 X 1/2 in Cup Point Gr8

Product Description

The VALUE COLLECTION MP40471 is a 10-32 x 1/2 inch cup point set screw manufactured from Grade 8 alloy steel. Set screws are headless fasteners used to secure a component — such as a collar, pulley, or gear — onto a shaft by applying direct pressure at the point of contact. The cup point design bites into the mating surface to resist rotation and axial movement. Driven with a 3/32 inch hex key, this screw meets ASME/ANSI B18.3 and ASTM F912 standards. This listing covers a package of 50 screws, suitable for production use or shop stock.

Cup point set screws in 10-32 UNF thread are widely used in light mechanical assemblies across HVAC equipment, electrical enclosures, pump components, and general industrial applications. The 1/2 inch overall length suits moderate-depth engagement requirements. Grade 8 alloy steel provides the elevated hardness and tensile strength needed in applications where the fastener must bite firmly into a steel or aluminum shaft without deforming under load. These screws are appropriate for any trade or maintenance professional who works with rotating or sliding shaft assemblies.

Key Features

• Cup point tip bites into shaft surface for positive retention against rotation and axial movement
• 10-32 UNF thread for fine-pitch engagement in standard tapped holes
• Grade 8 alloy steel construction for high hardness and tensile strength
• 3/32 inch internal hex drive compatible with standard hex keys and T-handle drivers
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Sold in a pack of 50 for production runs or bulk shop inventory

Compatibility

Designed as a standard 10-32 UNF cup point set screw suitable for any tapped hole conforming to ASME/ANSI B18.3 specifications in that thread size.

Installation Notes

Install and remove set screws using a properly sized 3/32 inch hex key to avoid rounding the drive socket. Ensure the mating shaft or component is clean and free of debris before tightening. De-energize and lock out any machinery before accessing rotating shaft assemblies. Do not exceed the torque capacity of the hex drive — a damaged socket requires screw extraction and replacement.
