Value Collection 602412PR Set Screw 1/2-20 X 3/4 in Cup Point

Product Description

The VALUE COLLECTION 602412PR is a 1/2-20 UNF cup point set screw manufactured from Austenitic Grade A2 stainless steel. It measures 3/4 inches in overall length and is driven by a 1/4-inch hex key. The cup point design bites into the mating surface to resist rotation and axial movement, making it suitable for shaft collars, shaft-to-hub assemblies, and other clamping applications where a permanent or semi-permanent hold is required. Manufactured to ASME/ANSI B18.3 and ASTM F880 standards, this screw is appropriate for use in corrosion-resistant or food-adjacent installations where stainless steel is specified. Licensed trade professionals and maintenance mechanics install this type of fastener across HVAC, plumbing, and general mechanical assemblies.

This set screw is intended for use in applications requiring a 1/2-20 UNF thread with a cup point seating geometry. Grade A2 stainless steel provides solid corrosion resistance in wet, humid, or mildly chemical environments without the need for additional coatings. Typical installations include shaft-collar retention, pulley and sprocket positioning, and valve stem assemblies. This screw is sold individually but must be ordered in a minimum quantity of 10 units per order.

Key Features

• 1/2-20 UNF thread provides fine-pitch engagement for precise clamping force control
• Cup point geometry bites into mating surface to prevent axial and rotational slippage
• Austenitic Grade A2 stainless steel resists corrosion in wet and humid service environments
• 1/4-inch hex key drive compatible with standard hex wrenches and T-handles
• Meets ASME/ANSI B18.3 and ASTM F880 dimensional and mechanical standards
• Headless profile allows flush or recessed installation in tapped through-holes

Compatibility

Designed as an OEM-style replacement or standard-service fastener for any assembly requiring a 1/2-20 UNF headless cup point set screw conforming to ASME/ANSI B18.3 and ASTM F880 specifications.

Installation Notes

Installation is performed by threading mechanics or technicians using a 1/4-inch hex key or Allen wrench rated for the required seating torque. Always de-energize, depressurize, or lock out the equipment before adjusting or replacing set screws in rotating or pressurized assemblies. Ensure the tapped hole is clean and free of debris before installation. Do not use impact drivers on set screws, as this can strip the hex socket or over-torque the fastener.
