Value Collection MP40361 Set Screw 1/4-20 5/16in Cup Point Gr8

Product Description

The VALUE COLLECTION MP40361 is a cup-point set screw designed for mechanical assemblies that require a secure, non-projecting fastener. Threaded 1/4-20 UNC and measuring 5/16 inches in overall length, this screw is driven by a 1/8-inch hex key and seats with a cup-point tip that bites into shaft material to resist rotation and axial movement. Manufactured from alloy steel to Grade 8 specifications, it delivers high tensile strength suitable for demanding industrial and mechanical service. Each package contains 50 screws and meets ASME/ANSI B18.3 and ASTM F912 standards.

Cup-point set screws like the MP40361 are used across a wide range of applications including HVAC blower assemblies, motor shaft collars, gear hubs, pulleys, and general mechanical fastening where a flush or recessed fastener is required. The 1/4-20 UNC thread size is one of the most common in light-to-medium duty mechanical assemblies, making this screw a practical stock item for maintenance shops, mechanical contractors, and equipment repair technicians.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped collars and hubs
• Cup point tip bites into shaft surface to resist rotation under load
• Grade 8 alloy steel construction for high tensile and shear strength
• 1/8-inch hex key drive for installation in confined spaces
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Sold in a pack of 50 for shop stock and service use

Compatibility

Designed as a standard 1/4-20 UNC cup-point set screw for use in any application calling for an ASME/ANSI B18.3 compliant headless set screw of this thread size and length.

Installation Notes

Installation is performed with a 1/8-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. De-energize and lock out any equipment before accessing shaft assemblies or rotating components. Do not substitute a worn or undersized hex key, as this can damage the drive recess and complicate removal. Thread engagement should be verified to be clean and free of debris before driving the screw to its seated position.
