Value Collection 602404PR Set Screw 1/2-20 X 1/2 in Cup Point Ss

Product Description

The VALUE COLLECTION 602404PR is a 1/2-20 x 1/2 inch cup point set screw manufactured from austenitic Grade A2 stainless steel. This headless fastener is driven by a 1/4 inch hex key and seats firmly against a shaft or mating surface using its cup point geometry to resist rotation and axial movement. It conforms to ASME/ANSI B18.3 and ASTM F880 standards, confirming dimensional accuracy and material traceability. The 1/2-20 UNF thread provides fine thread engagement suited to applications where vibration resistance or precise axial positioning is required. Licensed trades and industrial maintenance professionals install these fasteners across mechanical assemblies, rotating shafts, and equipment mounting applications.

This set screw is appropriate for use in mechanical, HVAC, plumbing, and industrial maintenance contexts where a flush or below-surface fastener is required to lock a collar, pulley, gear, or coupling onto a shaft. The fine UNF thread pitch makes it well suited for metal-to-metal engagement in light to medium duty assemblies. The austenitic Grade A2 stainless steel construction provides corrosion resistance in wet, chemical-exposed, or outdoor environments. It is sold in minimum order quantities of 50 units, making it suitable for shop stock, service van inventory, or production use.

Key Features

• Cup point geometry bites into shaft surface to resist torque and axial displacement
• 1/2-20 UNF fine thread for precise positioning and strong thread engagement in metal
• Austenitic Grade A2 stainless steel offers corrosion resistance without plating
• 1/4 inch hex drive compatible with standard hex keys and T-handle drivers
• Meets ASME/ANSI B18.3 and ASTM F880 for dimensional and material compliance
• Headless design sits flush or below surface to eliminate protrusion hazards

Compatibility

Designed as a standard 1/2-20 UNF cup point set screw conforming to ASME/ANSI B18.3 and ASTM F880, suitable as a direct replacement or stock fastener in any assembly specifying this thread size, point type, and drive configuration in austenitic stainless steel.

Installation Notes

Installation is performed with a 1/4 inch hex key or Allen driver; confirm the mating threaded hole is clean and free of debris before installation. De-energize and lock out any rotating equipment before inserting or adjusting set screws on live shafts. Do not exceed the tightening torque specified by the equipment manufacturer for the assembly. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when required by the application.
