Value Collection R40324463 Set Screw 1/2-13 X 5/8 in Cup Point

Product Description

The VALUE COLLECTION R40324463 is a 1/2-13 UNC cup point set screw manufactured from grade 18-8 stainless steel. Set screws are headless fasteners that thread fully into a tapped hole to secure a component — such as a collar, gear, pulley, or hub — against rotation or axial movement on a shaft. The cup point digs into the shaft surface to provide positive, bite-in retention. Drive is 1/4-inch hex (Allen key), which allows the fastener to sit flush or below the mating surface. At 0.025 pounds per unit, this is a precision-grade fastener suited to mechanical assemblies across HVAC, plumbing, electrical, and general industrial applications.

This set screw is appropriate for use in light-duty and medium-duty mechanical assemblies where flush or recessed fastening is required. Common install scenarios include securing shaft collars on blower assemblies, locking setscrews on motor couplings, and anchoring pulleys or sprockets in mechanical drive systems. The 18-8 stainless steel construction provides corrosion resistance suitable for wet or humid environments, including pool equipment rooms and outdoor mechanical enclosures. This fastener is sold individually; the minimum order quantity is 50 units.

Key Features

• Cup point geometry bites into shaft surface for positive retention without a separate locking element
• Grade 18-8 stainless steel construction resists corrosion in wet and humid service environments
• 1/4-inch hex drive allows installation with a standard Allen wrench or hex bit driver
• 1/2-13 UNC thread standard ensures compatibility with standard tapped holes and thread gauges
• Headless design permits fully recessed installation flush with or below the mating surface

Compatibility

Designed as a standard 1/2-13 UNC cup point set screw for use in any tapped hole conforming to 1/2-13 Unified National Coarse thread specifications.

Installation Notes

Installation is performed with a 1/4-inch hex key or hex bit driver; confirm the key fits fully seated before applying torque to avoid rounding the drive socket. De-energize and lock out any rotating equipment before servicing shaft-mounted components. Thread engagement should be verified to ensure the screw bears fully on the shaft contact surface. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener seating procedures.
