Value Collection MP40353 Cup Point Set Screw 10-24 X 0.5 in

Product Description

The VALUE COLLECTION MP40353 is a cup point set screw designed for secure mechanical fastening in assemblies where a headless profile is required. Threaded 10-24 UNC and measuring 0.5 inches in overall length, this screw is driven with a 3/32-inch hex key and seats its cup point directly into a mating shaft or surface to resist rotation and axial movement. Made from Grade 8 alloy steel, it delivers high tensile and torsional strength suitable for demanding industrial and mechanical applications. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards. The package contains 50 pieces, making it practical for both single repairs and higher-volume assembly work.

Cup point set screws like the MP40353 are widely used in shaft collars, pulleys, gears, couplings, and similar mechanical components where the fastener must lock a rotating or sliding part in position without protruding above the surface. They are common in industrial machinery, HVAC equipment drives, pump assemblies, and general manufacturing maintenance. Licensed tradespeople and maintenance technicians working in light industrial, commercial mechanical, and equipment repair environments will encounter this fastener type regularly.

Key Features

• 10-24 UNC thread for broad compatibility with standard tapped holes
• Cup point geometry bites into the mating surface for strong hold against rotation and axial shift
• Grade 8 alloy steel construction provides high tensile strength for demanding load conditions
• 3/32-inch hex drive for precise torque application with a standard hex key or Allen wrench
• Meets ASME/ANSI B18.3 and ASTM F912 standards for dimensional and mechanical compliance
• Headless design sits flush or below surface level, avoiding interference with surrounding components

Compatibility

Designed as a standard 10-24 UNC cup point set screw suitable for any tapped hole conforming to ASME/ANSI B18.3 dimensional requirements, including shaft collars, hubs, gears, and couplings across a wide range of mechanical assemblies.

Installation Notes

Set screws are typically installed by millwrights, maintenance technicians, or mechanical tradespeople using a 3/32-inch hex key. Always de-energize and lock out equipment before accessing any shaft or rotating assembly. Apply thread-locking compound if vibration is a concern, and do not overtighten, as excessive torque on alloy steel set screws can damage the mating shaft surface or strip the hex socket. Follow applicable machinery safety standards when servicing rotating equipment.
