Value Collection 409096PS Set Screw 1/2-13 X 1 in Cup Point

Product Description

The VALUE COLLECTION 409096PS is a 1/2-13 x 1 inch cup point set screw manufactured from Grade 2 steel with a bright, uncoated finish. Set screws are fully threaded fasteners with no head, designed to secure a component — such as a gear, pulley, or collar — against a shaft by applying direct point pressure. The cup point geometry bites into the mating surface for positive hold. This screw uses a square drive and conforms to Unified National Coarse (UNC) thread standards. Length is measured under the head, which on a headless fastener means the full body length of 1 inch. Installers in mechanical, HVAC, plumbing, and electrical trades encounter these fasteners in equipment assemblies and component mounting applications.

This set screw is suited for general industrial and trade use wherever a 1/2-13 UNC headless fastener is required. Common applications include securing shaft collars, sprockets, couplings, and similar rotating or stationary components in both residential and commercial mechanical systems. The uncoated steel finish is appropriate for indoor or protected environments. Minimum order quantity is 50 pieces, sold as a package quantity of 1.

Key Features

• Cup point geometry provides firm bite into shaft material for reliable hold
• Square drive for positive torque engagement with standard square-drive bits or keys
• 1/2-13 UNC thread for broad compatibility with standard tapped holes
• Grade 2 steel construction for general-purpose mechanical fastening
• Bright uncoated finish; suitable for dry or protected indoor installations
• Full 1 inch body length measured under head for consistent installation depth

Compatibility

Designed as a general-purpose 1/2-13 UNC cup point set screw for use in any application requiring a headless fastener of this thread size and length.

Installation Notes

Set screws of this size are typically installed by machinists, millwrights, or mechanical trade technicians using a square-drive bit or key of the correct size. De-energize and lock out any equipment before servicing components that contain set screws. Ensure the tapped hole is clean and threads are in good condition before installation. Do not exceed the torque rating of Grade 2 steel; overtightening can strip threads or fracture the fastener.
