Value Collection 40513 Set Screw 10-32 X 1/2 in Grade 8 50-pack

Product Description

The VALUE COLLECTION 40513 is a Grade 8 alloy steel set screw in a 10-32 UNF thread size with an overall length of 0.5 inches. It features a knurled cup point designed to bite into a shaft and resist rotation or axial movement without a protruding head. The 3/32-inch hex drive accepts a standard Allen key for installation in confined spaces. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards, making it suitable for precision mechanical assemblies where holding force and dimensional consistency are required. Each package contains 50 pieces. Machinists, maintenance technicians, and mechanical contractors are the typical installers.

This set screw is used in applications where a flush or recessed fastener is needed to secure a collar, gear, pulley, or similar component to a shaft. The knurled cup point provides enhanced grip on the mating surface compared to a plain cup point, making it well suited for moderate-to-high torque hold applications in industrial and commercial mechanical systems. The 10-32 UNF thread is a fine-pitch standard commonly found in instrument-grade and light mechanical assemblies.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Knurled cup point increases surface bite and resistance to loosening under vibration
• 10-32 UNF fine-pitch thread for precise engagement and reduced risk of cross-threading
• 3/32-inch hex drive compatible with standard Allen or hex key sets
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and performance standards
• Sold in a 50-piece pack for bench stock and field service kits

Compatibility

Designed as a standard 10-32 UNF Grade 8 set screw for use in any mechanical assembly or fastener application requiring this thread size, point style, and drive type.

Installation Notes

Installation is performed by machinists or mechanical technicians using a 3/32-inch hex key. Ensure the mating shaft is clean and free of burrs before seating the knurled cup point. De-energize and lock out any machinery before servicing components secured by set screws. Do not exceed the rated torque range for 10-32 Grade 8 fasteners as specified by ASME guidelines.
