Value Collection 409135PR Set Screw 3/4-10 X 3 in Cup Point

Product Description

The VALUE COLLECTION 409135PR is a 3/4-10 UNC cup point set screw manufactured from Grade 2 steel with a bright, uncoated finish. At 3 inches in length, this fastener is designed to secure components onto shafts or within assemblies by biting into the mating surface with its hardened cup point. The square drive accepts a matching square key or bit for installation and removal. This set screw is suited for general mechanical and industrial applications where a standard, non-plated steel fastener is appropriate and corrosion exposure is not a primary concern.

Cup point set screws like the 409135PR are commonly used in shaft collars, pulleys, gears, and similar rotating or stationary assemblies across HVAC, plumbing, electrical, and general mechanical systems. The cup point geometry provides a moderate grip on the mating surface without the deeper penetration of a cone point, making it a practical choice for applications where the shaft or housing may need to be repositioned. Sold individually with a minimum order quantity of 10 pieces.

Key Features

• 3/4-10 UNC thread for broad compatibility with standard inch-series tapped holes
• Cup point geometry provides reliable holding force with moderate surface contact
• Square drive reduces cam-out risk during installation and removal
• Grade 2 steel construction suitable for general-purpose mechanical assemblies
• Bright uncoated finish — no added plating or coating that could affect thread fit
• 3-inch length accommodates deeper engagement in thick hubs or collars

Compatibility

Designed as a general-purpose replacement or stock set screw for standard 3/4-10 UNC tapped applications in shaft collars, hubs, pulleys, and similar mechanical assemblies.

Installation Notes

Installation and removal requires a correctly sized square drive key or bit. Always de-energize or lock out equipment before accessing rotating shaft assemblies. Verify thread engagement is sufficient for the applied load before returning equipment to service. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener torque requirements.
