The VALUE COLLECTION -40502-1 is a 6-32 x 3/8-inch headless set screw with a knurled cup point, manufactured from Grade 8 alloy steel. It is driven by a 1/16-inch hex key and conforms to ASME/ANSI B18.3 and ASTM F912 standards. The knurled cup point bites into the mating surface to resist rotation and axial movement, making it a reliable fastener for locking collars, pulleys, gears, and shafts. This package contains 50 pieces. Machinists, millwrights, and maintenance technicians commonly use this screw in light mechanical assemblies where a low-profile, flush-mount fastener is required.
This set screw is suited for applications in residential and commercial mechanical systems, manufacturing equipment, HVAC components, and general industrial assemblies. The 6-32 UNC thread size is common in small-diameter shaft-collar and hub applications. The overall length of 3/8 inches allows engagement depth appropriate for thin-wall collars and light-duty clamping points. The Grade 8 alloy steel construction provides higher tensile strength than standard steel fasteners, supporting use in moderate-load mechanical connections.
Designed as a standard 6-32 UNC headless set screw for use in any application requiring ASME/ANSI B18.3 or ASTM F912 compliant fasteners with a knurled cup point.
Installation is performed by machinists or maintenance technicians using a 1/16-inch hex key. De-energize and lock out any equipment before installing or adjusting set screws on rotating assemblies. Do not exceed the rated engagement torque for the 6-32 thread size; overtightening can strip threads or fracture the point. Refer to applicable industry torque tables for Grade 8 alloy steel at this thread size.
