Value Collection 111209PR Set Screw 10-32 X 3/4 in Grade 8

Product Description

The VALUE COLLECTION 111209PR is a Grade 8 alloy steel set screw with a 10-32 UNF thread and an overall length of 3/4 inches. It features a knurled cup point designed to bite into a mating surface and resist rotation under load, making it a reliable fastener choice for shaft-to-hub assemblies, collars, and mechanical stops. Drive engagement is via a 3/32 inch hex key socket. Manufactured to ASME/ANSI B18.3 and ASTM F912 standards, this fastener meets the dimensional and mechanical requirements expected in precision assembly and maintenance applications. Machinists, maintenance technicians, and mechanical assemblers are the primary installers.

This set screw is suited for use in light industrial and commercial mechanical assemblies where a headless fastener is required to lock a component onto a shaft or within a housing. The knurled cup point provides added grip compared to a plain cup point, making it well-suited for applications involving vibration or cyclic loading. It is commonly used in motor shaft collars, pulley hubs, gear assemblies, and similar fixed-position fastener applications across HVAC equipment, pump assemblies, and general mechanical systems.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Knurled cup point increases surface grip and resistance to loosening under vibration
• 10-32 UNF thread for fine-thread precision fit
• 3/32 inch hex drive socket for standard hex key installation
• Headless profile allows full flush or sub-flush installation
• Manufactured to ASME/ANSI B18.3 and ASTM F912 standards

Compatibility

Designed as a standard headless set screw for use in any mechanical assembly requiring a 10-32 UNF threaded fastener with a knurled cup point. Verify thread engagement depth and mating component material before installation.

Installation Notes

Installation is performed by mechanical technicians or machinists using a 3/32 inch hex key or hex driver. Ensure the mating shaft or housing thread is clean and free of debris before driving the fastener. Do not overtighten, as the knurled cup point can damage soft shaft materials if excessive torque is applied. Always de-energize and lock out any equipment before servicing fasteners on rotating assemblies.
