Value Collection MP40475-1 Set Screw 1/4-28 Grade 8 50pk

Product Description

The VALUE COLLECTION MP40475-1 is a cup point set screw designed for mechanical assemblies requiring a secure, low-profile fastener with no protruding head. It features a 1/4-28 unified fine thread and measures 1/4 inch in overall length. The cup point digs into mating surfaces to resist rotation and axial movement, making it well suited for locking collars, hubs, pulleys, and shafts. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength for demanding industrial and mechanical applications. Installation requires a 1/8 inch hex key. This screw meets ASME/ANSI B18.3 and ASTM F912 standards and is sold in a package of 50.

This set screw is used in general mechanical, industrial, and light manufacturing settings wherever a headless fastener is needed to secure a component to a shaft or housing. Typical applications include motor shaft collars, gear hubs, sprocket mounts, and other assemblies where flush or recessed fastening is required. The fine 1/4-28 thread pitch provides precise adjustment and strong holding force in metal-to-metal contact. This package of 50 is appropriate for production runs or stocking a shop supply.

Key Features

• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Sold in a package of 50 for production or maintenance stocking

Compatibility

Designed as a standard-dimension replacement or stocking fastener for any assembly specifying a 1/4-28 UNF cup point set screw per ASME/ANSI B18.3.

Installation Notes

Installation is performed with a 1/8 inch hex key; de-energize and lock out any machinery before fastening or removing set screws in rotating assemblies. Do not exceed the rated seating torque for the thread size and material grade as specified in your assembly documentation. Inspect the cup point and mating shaft surface for damage before reuse. Applicable torque and installation procedures should follow manufacturer guidelines and relevant industry standards.
