Value Collection 409098PR Set Screw 1/2-13 X 1-1/2 in Cup Point

Product Description

The VALUE COLLECTION 409098PR is a cup point set screw designed for mechanical fastening applications where a headless, flush-mount fastener is required. Machined from Grade 2 steel with a bright uncoated finish, this screw features a 1/2-13 UNC thread and measures 1.5 inches in length under head. The cup point tip bites into the mating surface to resist rotational and axial movement, making it a reliable choice for securing collars, hubs, pulleys, and similar components to shafts. This part is sold individually but requires a minimum order of 50 pieces.

This set screw is suited for general industrial and mechanical maintenance applications across manufacturing, HVAC equipment assembly, and facility maintenance environments. The 1/2-13 UNC thread is a common fractional-inch coarse thread standard, fitting widely available tapped holes in machine components. The cup point geometry provides positive grip on both hardened and unhardened shaft materials. Licensed machinists, millwrights, and maintenance technicians typically source this fastener for equipment repair and assembly work.

Key Features

• Cup point tip provides firm bite into shaft or seating surface to resist movement under load
• 1/2-13 UNC coarse thread for broad compatibility with standard tapped components
• Grade 2 steel construction suitable for general-duty mechanical fastening
• Bright uncoated finish — no additional coating to account for in torque or clearance calculations
• Headless design allows flush or below-surface installation
• Length measured under head at 1.5 inches per fractional inch measurement standard

Compatibility

Designed as a standard 1/2-13 UNC cup point set screw for use in any tapped hole conforming to the 1/2-13 Unified National Coarse thread standard. No specific OEM model compatibility was provided in the product data.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a square drive key or bit sized to the fastener. Ensure the mating shaft and tapped hole are clean and free of debris before installation. Disengage and lock out all power to rotating equipment before servicing any shaft-mounted components. Do not exceed the rated load capacity of the Grade 2 steel specification for the intended application.
