Value Collection 101403PR Set Screw 5/16-18 X 2 in Cup Point

Product Description

The VALUE COLLECTION 101403PR is a cup point set screw designed for mechanical assemblies where a fastener must apply clamping force without a protruding head. Sized at 5/16-18 UNC thread by 2 inches overall length, this headless fastener is driven with a 5/32-inch hex key. Manufactured from Grade 8 alloy steel, it delivers high tensile strength suited to demanding hold-down and positioning applications. The cup point geometry bites into the mating surface to resist rotation and axial movement. It meets ASME/ANSI B18.3 and ASTM F912 standards for dimensional and mechanical compliance.

This set screw is used in shaft-to-hub connections, collar assemblies, and machine component positioning across industrial, mechanical, and maintenance applications. It is commonly installed by machinists, millwrights, and maintenance technicians working on rotating equipment, conveyor systems, motor shafts, and similar mechanical drives. The 5/16-18 coarse thread provides good engagement in steel, cast iron, and other ferrous components typical of industrial machinery.

Key Features

• 5/16-18 UNC thread for broad compatibility with standard tapped holes in ferrous assemblies
• 2-inch overall length provides deep thread engagement for high-load applications
• Cup point geometry resists rotation and axial displacement without marring surrounding material
• Grade 8 alloy steel construction delivers high tensile and proof load strength
• 5/32-inch hex drive accepts standard hex keys and T-handle drivers
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards

Compatibility

Designed as an OEM-style replacement or standard stock fastener for mechanical assemblies requiring a 5/16-18 UNC headless set screw with a cup point in Grade 8 alloy steel.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 5/32-inch hex key or Allen driver. De-energize and lock out all rotating equipment before installing or adjusting set screws. Thread the fastener by hand before applying torque to avoid cross-threading. Follow applicable machine manufacturer torque guidelines and ASME fastener standards when final-tightening.
