Value Collection 111177PR Set Screw 10-24 X 1/4 in Grade 8

Product Description

The VALUE COLLECTION 111177PR is a 10-24 x 1/4 inch knurled cup point set screw manufactured from Grade 8 alloy steel. Set screws are headless fasteners driven entirely below the surface of the mating part, used to secure a component — such as a collar, gear, or pulley — against rotation or axial movement on a shaft. This screw uses a 3/32 inch hex (Allen) drive and a knurled cup point, which bites into the shaft surface to provide firm, vibration-resistant holding force. It conforms to ASME/ANSI B18.3 and ASTM F912 standards. Maintenance technicians, millwrights, and HVAC and mechanical system installers commonly use this fastener during equipment assembly and repair.

This set screw is suited for light-duty to medium-duty mechanical assembly applications where a recessed drive and positive shaft engagement are required. Typical use cases include securing sheaves, sprockets, collars, and similar rotating components to shafts in HVAC equipment, pumps, motors, and general mechanical assemblies. The knurled cup point is particularly effective on softer shaft materials where a permanent or semi-permanent hold is needed. This screw is sold individually with a minimum order quantity of 100 pieces.

Key Features

• 10-24 UNC thread with 1/4 inch overall length for compact, flush installation
• Knurled cup point digs into shaft surface for vibration-resistant retention
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 3/32 inch hex drive accepts standard Allen keys for easy installation in confined spaces
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Fractional inch measurement type — suitable for standard US mechanical assemblies

Compatibility

Designed as a standard UNC set screw for use in any application requiring a 10-24 threaded, headless fastener with a knurled cup point and 3/32 inch hex drive conforming to ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Installation should be performed by a qualified technician or mechanic. De-energize and lock out all connected equipment before installation or removal. Use a properly sized 3/32 inch hex key to drive the screw to the manufacturer's specified torque for the application — do not over-tighten, as this can damage the shaft or strip the thread. Ensure the mating tapped hole is clean and free of debris before assembly.
