Value Collection 40507 Set Screw 8-32 X 0.5 in Grade 8 50pk

Product Description

The VALUE COLLECTION 40507 is a knurled cup point set screw designed for secure, vibration-resistant fastening in mechanical assemblies. Manufactured from Grade 8 alloy steel, this screw delivers high tensile strength and hardness suitable for demanding industrial and trade applications. It features an 8-32 UNC thread with an overall length of 0.5 inches and is driven by a 5/64-inch hex key. Conforming to ASME/ANSI B18.3 and ASTM F912 standards, it is appropriate for use where precise hold and repeatable installation are required. Each package contains 50 screws.

This set screw is suited for use in shaft-collar connections, pulleys, gears, knobs, and similar mechanical components where the knurled cup point provides a biting grip into the mating surface. It is commonly used in HVAC equipment assemblies, electrical motor shafts, pump components, and general mechanical maintenance applications. The compact 0.5-inch length makes it appropriate for shallow-depth installations in tight spaces. Professionals in HVAC, plumbing, and electrical trades will find this size a standard fit for many OEM and aftermarket mechanical assemblies.

Installation Notes

Installation is performed by threading mechanics, HVAC technicians, electricians, or millwrights using a 5/64-inch hex key. Always de-energize and lock out equipment before accessing rotating components or shaft assemblies. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque rating specified by the equipment manufacturer for this thread size and grade.
