Value Collection MP40476 Set Screw 1/4-28 X 5/16 in Grade 8

Product Description

The VALUE COLLECTION MP40476 is a cup point set screw designed for secure, vibration-resistant fastening in mechanical assemblies. Manufactured from Grade 8 alloy steel, this headless screw uses a 1/8-inch hex key drive and features a cup point tip that bites into the mating surface to resist rotation and axial movement. The 1/4-28 UNF thread provides fine-pitch engagement well suited to applications requiring precise adjustment or firm clamping force. Each package contains 50 pieces. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards, making it appropriate for industrial, mechanical, and equipment maintenance applications.

Cup point set screws in the 1/4-28 thread size are commonly used to lock collars, pulleys, gears, and sprockets onto shafts. They are also used to secure knobs and handwheels. The 5/16-inch overall length suits thin-wall or close-tolerance assemblies where a longer screw would bottom out or interfere with adjacent components. Trade professionals in HVAC, mechanical, electrical, and general equipment service will encounter this fastener in motor shaft assemblies, linkage hardware, and control components.

Compatibility

Designed as a standard 1/4-28 UNF cup point set screw suitable for use in any application requiring an ASME/ANSI B18.3 compliant headless hex drive fastener of this thread size and length.

Installation Notes

Installation requires a 1/8-inch hex key or Allen driver. De-energize and lock out any equipment before accessing shaft or collar assemblies. Ensure the mating surface is clean and free of debris before seating the cup point. Do not exceed the rated capacity of the tapped hole or mating material, particularly when installing into softer base metals.
