Value Collection 101275PR Set Screw 10-32 5/16 in Cup Point

Product Description

The VALUE COLLECTION 101275PR is a headless set screw designed to secure a component within or against another part without protruding beyond the surface. Threaded 10-32 UNF with an overall length of 5/16 inches, it features a cup point for reliable grip and bite into the mating surface. Driven by a 3/32-inch hex key, it is manufactured from alloy steel to Grade 8 specification. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards, making it suitable for precision mechanical assemblies where hold strength and dimensional consistency are required. Machinists, maintenance technicians, and industrial tradespeople regularly specify this screw for shaft collars, pulleys, and similar mechanical components.

This set screw is used in light mechanical and industrial assembly applications where a flush or recessed fastener is needed. The cup point style is the most common general-purpose point type, providing a moderate bite into soft to medium-hardness shaft materials. Typical installation scenarios include motor shaft collars, gear hubs, and adjustment mechanisms in HVAC equipment, pumps, and other rotating assemblies. Sold in a minimum order quantity of 100 per order.

Key Features

• Thread size 10-32 UNF for compatibility with fine-thread mechanical assemblies
• Cup point geometry provides positive engagement with shaft or seating surface
• Alloy steel construction at Grade 8 delivers high tensile and torsional strength
• 3/32-inch hex drive accepts 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 for clearance-sensitive applications

Compatibility

Designed as a standard 10-32 UNF headless cup-point set screw for use in any mechanical assembly or component requiring a Grade 8 alloy steel fastener to ASME/ANSI B18.3 specification.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 3/32-inch hex key. Always de-energize and lock out any equipment before installing or adjusting set screws on rotating components. Do not overtighten; apply only enough torque to seat the cup point firmly against the mating surface without stripping the socket. Thread engagement and seating should be verified before returning the assembly to service.
