Value Collection 409100PR Set Screw 1/2-13 X 2 in Cup Point

Product Description

The VALUE COLLECTION 409100PR is a 1/2-13 UNC cup point set screw measuring 2 inches in length, manufactured from Grade 2 steel with a bright, uncoated finish. Set screws of this type are fully threaded, headless fasteners used to secure a component — such as a collar, pulley, sprocket, or gear — against a shaft. The cup point digs into the mating surface under torque, providing positive holding force without a protruding head. This screw is sold in multiples of 10 units minimum.

Cup point set screws in 1/2-13 UNC thread are common in light-duty mechanical assemblies across HVAC, plumbing, electrical, and general industrial applications. They are frequently installed during equipment fabrication, maintenance, and field repair wherever a low-profile, shaft-locking fastener is required. The 2-inch length suits deeper shaft engagement or thicker hub walls where shorter set screws would not provide adequate thread engagement.

Key Features

• Cup point geometry bites into mating shaft surface for positive rotational and axial holding
• 1/2-13 UNC coarse thread for reliable engagement in standard tapped holes
• 2-inch length provides deep thread engagement for thicker hubs and collars
• Grade 2 steel construction suitable for light-to-medium duty applications
• Bright uncoated finish — no coating buildup to affect thread fit
• Square drive for use with standard square-socket set screw keys

Compatibility

Designed as a standard 1/2-13 UNC cup point set screw for use in any tapped hole or threaded component requiring this thread size, length, and point style.

Installation Notes

Set screws in this size are typically installed by machinists, millwrights, or maintenance technicians using a square-socket hex key or T-handle driver. Always ensure the mating tapped hole is clean and free of debris before installation. Do not overtighten — follow the component manufacturer's torque guidance for the hub or collar material. Power down or de-energize any rotating equipment fully before installing or removing shaft-mounted fasteners.
