Value Collection 602289PR Set Screw 5/16-18 X 1-3/4 in

Product Description

The VALUE COLLECTION 602289PR is a cup point set screw designed for industrial and mechanical fastening applications where a secure, permanent hold on a shaft or workpiece is required. Manufactured from austenitic Grade A2 stainless steel, this screw resists corrosion and oxidation in demanding service environments. It features a 5/16-18 UNC thread with an overall length of 1-3/4 inches and is driven by a 5/32-inch hex (Allen) key. Installation is straightforward for machinists, maintenance technicians, and mechanical tradespeople working with shafts, collars, pulleys, and similar assemblies.

This set screw is suited for use in HVAC equipment assemblies, pump and motor shaft collars, fan blade hubs, and general mechanical applications where a flush-mount, headless fastener is needed. The cup point geometry bites into the mating surface to resist rotation and axial movement under load. It is appropriate for both light industrial and commercial mechanical installations. Orders are fulfilled in multiples of 10 units per the minimum order quantity requirement.

Key Features

• Cup point tip bites into shaft or workpiece surface for positive rotational and axial hold
• Austenitic Grade A2 stainless steel construction resists corrosion and oxidation
• 5/16-18 UNC thread for compatibility with standard tapped holes
• 1-3/4 inch overall length provides deep thread engagement
• 5/32-inch hex drive accepts standard Allen key or hex bit drivers
• Meets ASME/ANSI B18.3 and ASTM F880 fastener standards

Compatibility

Designed as a standard UNC-thread set screw for use in any tapped 5/16-18 hole requiring a cup point, headless fastener in stainless steel construction.

Installation Notes

Installation is performed by mechanical or maintenance technicians using a calibrated 5/32-inch hex key or hex bit driver. De-energize and lock out any rotating equipment before servicing shaft collars, pulleys, or couplings secured by set screws. Ensure the tapped hole is clean and free of debris before threading the screw in by hand to avoid cross-threading. Follow applicable ASME standards and equipment manufacturer torque guidelines when tightening.
