Value Collection 101459PR Set Screw 3/8-16 X 7/8 in Cup Point

Product Description

The VALUE COLLECTION 101459PR is a cup point set screw designed for secure shaft and collar fastening in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and resistance to loosening under load. The cup point geometry bites into the mating surface to prevent rotational and axial movement without requiring a through-hole. It features a 3/16-inch hex drive and conforms to ASME/ANSI B18.3 and ASTM F912 standards, making it a reliable choice for precision industrial and mechanical applications. Thread size is 3/8-16 UNC with an overall length of 7/8 inches.

This set screw is suited for use in machine assemblies, power transmission components, and equipment where shafts, hubs, collars, pulleys, or gears require firm axial and rotational retention. The cup point style is commonly installed in moderate to high-load applications where a slight indentation on the shaft is acceptable. Machinists, millwrights, and maintenance technicians will find this fastener appropriate for both OEM assembly and field repair work across industrial and commercial mechanical systems.

Key Features

• Cup point geometry provides strong shaft retention by creating a mechanical bite in the mating surface
• Grade 8 alloy steel construction delivers high tensile and proof load strength
• 3/8-16 UNC thread size for broad compatibility with standard tapped holes
• 3/16-inch hex drive accepts standard hex keys and Allen wrenches
• Conforms to ASME/ANSI B18.3 and ASTM F912 standards
• Overall length of 7/8 inches suits a range of collar and hub thicknesses

Compatibility

Designed as a standard UNC replacement or assembly set screw for mechanical components with 3/8-16 tapped set screw holes requiring a cup point style fastener.

Installation Notes

Installation requires a 3/16-inch hex key or Allen wrench. Power down and de-energize any rotating equipment fully before servicing shaft collars, hubs, or couplings. Apply appropriate thread-locking compound if vibration is a concern in the application. Follow applicable machinery safety codes and torque guidelines established by the equipment manufacturer.
