Value Collection MP40481 Set Screw 5/16-24 X 3/8 in Grade 8

Product Description

The VALUE COLLECTION MP40481 is a cup point set screw designed for secure, flush fastening in mechanical assemblies where a protruding fastener head is not practical. Manufactured from Grade 8 alloy steel, this fully threaded headless screw delivers high tensile and torsional strength suitable for demanding industrial and trade applications. The cup point tip bites into the mating surface to resist rotation and axial movement. Thread size is 5/16-24 UNF with an overall length of 3/8 inches. Drive is a 5/32-inch hex socket. Sold in a package of 50. Meets ASME/ANSI B18.3 and ASTM F912 standards.

Cup point set screws like the MP40481 are used across a broad range of mechanical and equipment applications including HVAC equipment assemblies, shaft-to-collar connections, pulley and gear retention, and general industrial fabrication. The fine UNF thread pattern provides positive engagement and resist loosening under vibration. This fastener is well suited for maintenance technicians, millwrights, and field service professionals working on rotating equipment and mechanical drive systems.

Key Features

• Cup point tip grips mating surface to resist axial and rotational movement
• Grade 8 alloy steel construction for high tensile and torsional strength
• 5/16-24 UNF fine thread for positive engagement and vibration resistance
• 5/32-inch hex socket drive for standard hex key installation
• Fully headless design allows flush or below-surface seating
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards

Compatibility

Designed as an OEM-style replacement or service stock set screw for mechanical assemblies requiring a 5/16-24 UNF cup point fastener with a 5/32-inch hex drive.

Installation Notes

Installation is performed using a 5/32-inch hex key or Allen driver. De-energize and lock out all equipment before servicing any mechanical assembly. Ensure mating threads are clean and free of debris before driving the fastener. Do not exceed the torque capacity of the alloy steel fastener or the mating material.
