Value Collection MP40483 Set Screw 5/16-24 X 3/4 in Cup Point Gr8

Product Description

The VALUE COLLECTION MP40483 is a Grade 8 alloy steel set screw designed for secure, flush fastening in mechanical assemblies. With a 5/16-24 UNF thread and a 3/4-inch overall length, this fastener delivers high clamping force without a protruding head. The cup point bites into the mating surface to resist rotation and axial movement. It is driven with a 5/32-inch hex key and conforms to ASME/ANSI B18.3 and ASTM F912 standards. Machinists, maintenance technicians, and industrial assemblers install these in shafts, collars, pulleys, and similar precision components where a headless fastener is required.

This set screw is suited for use in rotating equipment, shaft-to-hub connections, and mechanical assemblies that demand a reliable hold under load. The 5/16-24 UNF thread is a fine-pitch designation commonly found in precision machinery and motion-control hardware. The Grade 8 alloy steel construction provides the tensile strength needed for high-stress applications. This listing is sold as a pack of 50 pieces, making it practical for shop stock, maintenance carts, and production line use.

Key Features

• Grade 8 alloy steel construction for high tensile strength in demanding applications
• Cup point geometry grips mating shaft surface to resist axial and rotational movement
• 5/16-24 UNF fine-pitch thread for precise engagement and secure fit
• 5/32-inch hex drive for standard Allen key installation
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Sold in a 50-piece pack for shop stocking and production use

Compatibility

Designed as a standard headless set screw for use in any mechanical application requiring a 5/16-24 UNF thread and 3/4-inch overall length cup point fastener.

Installation Notes

Installation is performed with a 5/32-inch hex key or Allen wrench. De-energize and lock out all equipment before accessing rotating shafts or assemblies. Ensure the mating bore is clean and threads are free of debris before driving the screw to the specified seating torque per your equipment service documentation. Do not exceed the rated capacity of the fastener material grade.
