Value Collection 101413PR Set Screw 5/16-24 X 1/2 in Cup Point

Product Description

The VALUE COLLECTION 101413PR is a cup point set screw designed for general industrial and mechanical fastening applications. Manufactured from Grade 8 alloy steel, this fastener delivers the high tensile strength and hardness required for secure shaft-to-hub connections, collar retention, and positioning applications. The 5/16-24 UNF thread pattern and 1/2-inch overall length make it suited for precision assemblies where fine thread engagement is required. It is driven with a 5/32-inch hex key. This screw conforms to ASME/ANSI B18.3 and ASTM F912 standards, ensuring dimensional consistency across production and maintenance environments. Sold in a minimum order quantity of 100 pieces.

This set screw is commonly used in manufacturing, MRO, and light industrial settings. Typical applications include locking set collars, shaft couplings, sprockets, pulleys, and other rotating or stationary mechanical components where a recessed drive and cup point are required. The fine UNF thread pitch provides controlled tightening and improved resistance to loosening under vibration. Machinists, maintenance technicians, and assembly personnel are the primary installers.

Key Features

• Grade 8 alloy steel construction for high tensile strength and hardness
• Cup point geometry bites into shaft surface for positive retention
• 5/16-24 UNF fine thread for controlled engagement and vibration resistance
• 5/32-inch hex drive for use with standard Allen or hex key tooling
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional standards
• Sold in multiples of 100 for production and stocking use

Compatibility

Designed as a standard UNF set screw for use in any application requiring a 5/16-24 threaded fastener with cup point geometry and hex drive, including collars, couplings, and mechanical assemblies that conform to ASME/ANSI B18.3 specifications.

Installation Notes

Installation requires a 5/32-inch hex key or Allen wrench. De-energize and lock out any machinery before installing or adjusting set screws on rotating components, following applicable OSHA lockout/tagout procedures. Do not exceed the rated torque capacity of the fastener for the material grade. Inspect threads for contamination or damage before installation to ensure full engagement and proper seating of the cup point.
