Value Collection 111197PR Set Screw 10-32 X 1/4 in Grade 8

Product Description

The VALUE COLLECTION 111197PR is a 10-32 UNF set screw with a knurled cup point, manufactured from Grade 8 alloy steel for reliable holding strength in demanding fastening applications. The knurled cup point digs into the mating surface to resist rotation and axial movement without requiring a through-hole. At 1/4 inch overall length, this screw is sized for compact assemblies where space is limited. It is driven with a 3/32-inch hex key and meets ASME/ANSI B18.3 and ASTM F912 standards. Maintenance technicians, millwrights, and mechanical contractors install these to secure collars, pulleys, gears, and shaft-mounted components in HVAC, plumbing, and light industrial equipment.

This set screw is suited for applications requiring a secure, low-profile fastener with no protruding head. Typical uses include locking shaft collars, set-collar assemblies, fan hubs, and similar rotating or sliding components found in residential and commercial mechanical systems. The knurled cup point provides superior bite compared to a plain cup point, making it a practical choice where vibration or frequent cycling is present.

Key Features

• 10-32 UNF thread for fine-pitch engagement and strong holding power
• Knurled cup point bites into mating surface to resist loosening under vibration
• Grade 8 alloy steel construction for high tensile and torsional strength
• 3/32-inch hex drive for installation with a standard Allen or hex key
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• 1/4-inch overall length suits compact collar and hub assemblies

Compatibility

Designed as a standard 10-32 UNF set screw for use in shaft collars, hubs, pulleys, and similar mechanical assemblies that accept a headless hex-drive fastener with a knurled cup point.

Installation Notes

Installation is performed with a 3/32-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the socket. De-energize and lock out any rotating equipment before servicing shaft-mounted components. Verify thread engagement depth and mating surface condition before final tightening. Minimum order quantity is 100 pieces per order.
