Value Collection 101153PR Set Screw 6-32 X 3/8 in Cup Point Grade 8

Product Description

The VALUE COLLECTION 101153PR is a cup point set screw designed for secure fastening applications where a flush or recessed fastener is required. Manufactured from Grade 8 alloy steel, this fully threaded screw measures 3/8 inches in overall length with a 6-32 UNC thread size. It is driven by a 1/16 inch hex key and meets ASME/ANSI B18.3 and ASTM F912 standards. The cup point geometry bites into the mating surface to resist rotation and axial movement, making it well suited for locking shafts, collars, and similar mechanical assemblies. Machinists, maintenance technicians, and industrial mechanics are the typical installers.

This set screw is used in light mechanical assemblies where a compact, low-profile fastener is needed to secure rotating components such as shaft collars, pulleys, gears, and knobs. The 6-32 thread size fits standard tapped holes found in small-diameter shafts and precision components common in HVAC equipment, motors, and general industrial machinery. The cup point provides a reliable grip on both hardened and unhardened shaft materials without the need for a through-hole.

Key Features

• Grade 8 alloy steel construction for high tensile strength in demanding applications
• Cup point geometry bites into mating surfaces to resist loosening under vibration
• 1/16 inch hex drive allows installation in confined spaces with a standard hex key or Allen wrench
• 6-32 UNC thread standard ensures compatibility with common tapped holes in small mechanical components
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and performance standards
• Fully threaded along the 3/8 inch overall length for maximum engagement

Compatibility

Designed as a standard replacement or stock fastener for any application requiring a 6-32 UNC cup point set screw with a 1/16 inch hex drive, conforming to ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Installation requires a 1/16 inch hex key or Allen wrench. Ensure the tapped receiving hole is clean and properly threaded to 6-32 UNC specification before driving the screw. De-energize and lock out any equipment before accessing rotating components. Avoid over-tightening, which can strip the small hex socket or damage the mating shaft surface.
