Value Collection 111199PR Set Screw 10-32 X 5/16 in Grade 8

Product Description

The VALUE COLLECTION 111199PR is a 10-32 x 5/16 inch headless set screw with a knurled cup point, manufactured from Grade 8 alloy steel. It accepts a 3/32 inch hex key drive and meets ASME/ANSI B18.3 and ASTM F912 standards. Set screws of this type are used to secure components such as collars, pulleys, gears, and sprockets onto shafts by bearing down against the mating surface. The knurled cup point provides positive grip and resistance to backing out under vibration or torque. Suitable for precision mechanical assemblies where a flush or recessed fastener is required. Sold individually with a minimum order quantity of 100 pieces.

This set screw is appropriate for use in mechanical, HVAC, electrical, and general industrial applications wherever a #10-32 UNF threaded socket set screw is specified. The fine unified thread (UNF) provides high clamping force in compact fastener geometry. Typical installations include shaft-to-hub retention in fan assemblies, motor mounts, and bracket hardware. Machinists, millwrights, and HVAC technicians routinely use this fastener type for field and shop assembly work.

Key Features

• 10-32 UNF thread for high clamping force in a small fastener profile
• Knurled cup point grips mating surfaces and resists backing out under vibration
• Grade 8 alloy steel construction for high tensile and torsional strength
• 3/32 inch hex key drive — standard and widely available tooling
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Overall length of 5/16 inches measured as full screw length

Compatibility

Designed as a standard replacement or stock fastener for any application specifying a 10-32 x 5/16 inch knurled cup point set screw with a 3/32 inch hex drive, conforming to ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Installation is performed by machinists, millwrights, or qualified technicians using a 3/32 inch hex key. De-energize and lock out any equipment before installing or removing set screws in rotating assemblies. Do not overtighten — follow the torque specifications provided by the equipment manufacturer for the thread size and material grade. Verify thread engagement depth is sufficient for the application before applying final torque.
