Value Collection 409085PS Set Screw 7/16-14 X 1 in Cup Point

Product Description

The VALUE COLLECTION 409085PS is a 7/16-14 UNC cup point set screw designed for mechanical fastening applications where a flush or recessed fastener is required. Manufactured from Grade 2 steel with a bright, uncoated finish, this set screw measures 1 inch in length under head and uses a square drive. The cup point geometry bites into the mating shaft or surface to resist rotational and axial movement without a protruding head. It is sized for standard fractional inch threading and suits general-purpose industrial and mechanical assembly work.

This set screw is used in a wide range of mechanical applications including shaft collars, shaft couplings, pulleys, gears, and similar components where a headless fastener is needed to lock a part onto a shaft or against a surface. It is appropriate for light to medium duty assemblies in residential, commercial, and industrial settings. Machinists, millwrights, maintenance technicians, and mechanical contractors commonly install this type of fastener during equipment assembly or field repair work.

Key Features

• 7/16-14 UNC thread size for compatibility with standard fractional inch tapped holes
• 1 inch length measured under head for consistent seating depth
• Cup point geometry grips shaft surface to resist slippage under load
• Square drive style for use with standard square key wrenches
• Grade 2 steel construction for general-purpose fastening duty
• Bright, uncoated finish — no added plating or coating

Compatibility

Designed as a general-purpose 7/16-14 UNC cup point set screw suitable for standard fractional inch tapped holes in shaft collars, couplings, pulleys, and similar mechanical components requiring a headless locking fastener.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a square key wrench sized to the drive. Ensure the tapped hole is clean and free of debris before threading the screw. Do not overtighten, as over-torquing Grade 2 steel fasteners can strip threads or fracture the screw. Consult applicable machinery documentation for recommended seating torque if specified by the equipment manufacturer.
