Value Collection MP40328 Cup Point Set Screw 6-32 Pack of 50

Product Description

The VALUE COLLECTION MP40328 is a cup point set screw designed for mechanical fastening applications where a headless, flush-mounted fastener is required. Built from Grade 8 alloy steel, this screw delivers high tensile strength suited for demanding clamping and locking duties. The 6-32 UNC thread with an overall length of 0.25 inches is driven by a 1/16-inch hex key, making it a compact solution for tight assemblies. It conforms to ASME/ANSI B18.3 and ASTM F912 standards. This package contains 50 pieces, making it a practical quantity for shop stock or production use. Installed by machinists, maintenance technicians, and mechanical assembly professionals.

Cup point set screws like the MP40328 are used in a wide range of mechanical assemblies, including shaft-to-hub connections, collars, pulleys, knobs, and gear hubs. The cup point geometry bites into the mating surface to resist rotation and axial movement. This 6-32 size is common in light-duty and precision instrument applications, electronics enclosures, and small mechanical assemblies found in residential and commercial HVAC equipment, motors, and similar hardware.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Cup point geometry provides positive bite on mating shafts and surfaces
• 6-32 UNC thread for compatibility with standard tapped holes in light mechanical assemblies
• Driven by 1/16-inch hex key for access in confined spaces
• Meets ASME/ANSI B18.3 and ASTM F912 standards
• Sold in a 50-piece pack to support shop stock and production needs

Compatibility

Designed as a standard 6-32 UNC cup point set screw for use in any tapped hole conforming to ASME/ANSI B18.3 specifications in light mechanical and precision assemblies.

Installation Notes

Set screws are typically installed by machinists or maintenance technicians using a 1/16-inch hex key. Always ensure the mating shaft or surface is clean and free of debris before tightening. Do not exceed the rated torque capacity of the 6-32 thread to avoid stripping. Confirm the tapped hole thread class matches the screw specification before installation.
