Value Collection 101147PR Set Screw 6-32 X 3/16 in Cup Point

Product Description

The VALUE COLLECTION 101147PR is a cup point set screw designed for secure, headless fastening in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to loosening under vibration and load. The cup point digs into the mating surface to resist axial and rotational movement, making it well suited for shaft-to-hub connections and similar holding applications. Driven by a 1/16-inch hex key, the 6-32 UNC thread and 3/16-inch overall length place this screw in the small-fastener range commonly used in precision mechanical and light industrial work. Machinists, maintenance technicians, and assembly professionals install this type of fastener in a wide range of equipment.

This set screw is used in applications where a flush or recessed fastener is required and a protruding head is not acceptable. Typical installations include shaft collars, gears, pulleys, and couplings where the cup point creates a locking indent in the shaft surface. The 6-32 UNC thread is a standard machine screw thread found across a broad range of mechanical equipment, tooling, and enclosure hardware. The Grade 8 alloy steel construction meets ASME/ANSI B18.3 and ASTM F912 standards, making it appropriate for demanding holding applications. Sold individually per package; minimum order quantity is 100 pieces.

Key Features

• Cup point geometry bites into mating surface to resist axial and rotational movement
• Grade 8 alloy steel construction for high tensile and proof-load strength
• 6-32 UNC thread standard for broad compatibility with common machine screw tapped holes
• 1/16-inch hex drive for use with standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design allows fully recessed installation flush with or below the work surface

Compatibility

Designed as a standard 6-32 UNC cup point set screw for use in any tapped hole conforming to the 6-32 thread specification. Suitable for shaft collars, couplings, pulleys, and other mechanical assemblies requiring a recessed headless fastener.

Installation Notes

Installation requires a 1/16-inch hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. De-energize and lock out any machinery before accessing shaft or coupling assemblies. Thread engagement depth should be sufficient to achieve the required holding force for the application. Follow applicable industry standards and equipment manufacturer guidelines for proper seating and inspection of cup point set screws.
