Value Collection MP40351 Set Screw 10-24 X 3/8 in Grade 8 50pk

Product Description

The VALUE COLLECTION MP40351 is a cup point set screw designed for secure, positive locking in a wide range of mechanical assemblies. Sized at 10-24 UNC thread with a 3/8-inch overall length, this fastener is driven by a 3/32-inch hex key and terminates in a cup point that bites into the mating surface to resist rotation and axial movement. Manufactured from alloy steel to Grade 8 specification, it delivers high tensile and torsional strength suitable for demanding industrial and mechanical applications. This package contains 50 pieces, making it practical for shop stock or service vehicles. Meets ASME/ANSI B18.3 and ASTM F912 standards.

Cup point set screws of this size are commonly used to secure pulleys, gears, collars, and hubs to shafts in light to medium-duty machinery, HVAC equipment drives, pump assemblies, and general mechanical systems. The 10-24 UNC thread is a widely encountered size across commercial and industrial equipment, and the Grade 8 alloy steel construction suits applications where higher clamping force and fatigue resistance are required compared to standard steel fasteners. Suitable for use by mechanical contractors, HVAC technicians, millwrights, and maintenance professionals.

Key Features

Compatibility

Designed as an OEM-style replacement or standard shop-stock set screw for mechanical assemblies requiring a 10-24 UNC cup point fastener with a 3/8-inch overall length.

Installation Notes

Installation should be performed by qualified mechanical or trade professionals using a calibrated 3/32-inch hex key. Ensure the shaft and collar or hub bore are clean and free of debris before seating the screw. Thread engagement should be confirmed before applying drive torque to avoid cross-threading. Always de-energize and lock out equipment before servicing any rotating assembly containing this fastener.
