Value Collection 111185PR Set Screw 10-24 X 1/2 in Grade 8

Product Description

The VALUE COLLECTION 111185PR is a headless set screw designed to secure components onto shafts and in bores without protruding above the mating surface. It features a knurled cup point that bites into the mating material for a firm, vibration-resistant hold. The fastener is manufactured from Grade 8 alloy steel, which provides high tensile strength suitable for demanding mechanical and industrial applications. Drive engagement is handled by a 3/32 inch hex key socket. Installers in mechanical, HVAC, plumbing, and electrical trades will encounter this fastener when assembling or servicing equipment with shaft-mounted components such as pulleys, collars, and couplings.

This set screw is suited for use in residential and commercial equipment assemblies where a flush or recessed fastener is required. Typical applications include securing set collars, sprockets, and gear hubs to shafts. The 10-24 UNC thread and 1/2 inch overall length make it a common size in light to medium-duty mechanical assemblies across HVAC blower assemblies, pump drive systems, and general industrial equipment. It meets ASME/ANSI B18.3 and ASTM F912 standards for socket set screws.

Key Features

• Knurled cup point provides positive grip and resists loosening under vibration
• Grade 8 alloy steel construction for high tensile and torsional strength
• 10-24 UNC thread for broad compatibility with standard tapped holes
• 3/32 inch hex drive socket for precise torque application with a standard hex key
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless design sits flush or below the mating surface

Compatibility

Designed as a standard 10-24 UNC socket set screw for use in any tapped hole or threaded bore conforming to 10-24 UNC thread specification in mechanical, HVAC, and industrial equipment assemblies.

Installation Notes

Installation is performed with a 3/32 inch hex key or T-handle driver. De-energize all equipment and relieve any mechanical load on the assembly before removing or installing set screws. Confirm the mating tapped hole is clean and free of debris before threading in the fastener. Follow applicable equipment manufacturer torque guidelines for Grade 8 socket set screws of this size.
