Value Collection 111211PR Set Screw 10-32 X 1 in Grade 8

Product Description

The VALUE COLLECTION 111211PR is a 10-32 x 1 inch knurled cup point set screw manufactured from Grade 8 alloy steel. Set screws are headless fasteners that thread fully into a tapped hole to secure a component, such as a collar, gear, or pulley, against rotation or axial movement on a shaft. The 3/32 inch hex drive accepts a standard hex key for installation and adjustment. Conforming to ASME/ANSI B18.3 and ASTM F912 standards, this fastener is suited for applications where high clamping force and reliable hold are required. The knurled cup point bites into the mating surface to resist loosening under vibration. Installed by mechanical technicians, HVAC service techs, and maintenance professionals.

This set screw is used wherever a 10-32 UNF threaded socket set screw is required. Common applications include securing shaft collars, motor couplings, fan hubs, and mechanical drive components in residential and light commercial HVAC equipment, refrigeration systems, and general industrial machinery. Overall length is measured as a full 1 inch, which suits deeper engagement in thicker collars or hub assemblies where a shorter screw may not provide adequate holding force.

Key Features

• 10-32 UNF thread for precise fit in standard tapped holes
• Knurled cup point grips mating surface to resist loosening under vibration
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 3/32 inch hex drive compatible with standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design sits flush or below the surface of the receiving component

Compatibility

Designed as a standard 10-32 UNF socket set screw for use in any application requiring a Grade 8 alloy steel knurled cup point fastener conforming to ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Installation requires a 3/32 inch hex key. Ensure the receiving component is de-energized and stationary before installing or adjusting set screws on rotating assemblies. Thread the screw in by hand first to confirm alignment and avoid cross-threading, then tighten with a hex key to the specification required by the assembly design. Applying a thread-locking compound may be appropriate in high-vibration environments.
