Value Collection 409062PR Set Screw 5/16-18 X 1.5 in Cup Point

Product Description

The VALUE COLLECTION 409062PR is a cup point set screw designed for secure fastening applications in mechanical assemblies, fixtures, and equipment. Manufactured from Grade 2 steel with a bright uncoated finish, this screw features a 5/16-18 UNC thread and measures 1.5 inches in length under head. The cup point tip bites into the mating surface to resist rotation and axial movement without requiring a through-hole. Installed using a square drive, it suits a wide range of industrial and trade applications where a flush, headless fastener is required.

This set screw is suited for use in collars, hubs, pulleys, sprockets, and similar components where a fastener must seat below the surface of the workpiece. It is commonly used in HVAC equipment assemblies, plumbing fixtures, electrical enclosures, and general mechanical installations. The fractional inch sizing follows standard UNC thread conventions, making it straightforward to source matching hardware. Sold individually per package with a minimum order quantity of 100 pieces.

Key Features

• Cup point tip creates a positive bite into mating surfaces, resisting rotation and axial load
• 5/16-18 UNC thread for compatibility with standard fractional inch hardware
• 1.5-inch length under head suits deeper engagement applications
• Grade 2 steel construction provides adequate strength for general-duty fastening
• Square drive socket for positive torque transfer during installation
• Bright uncoated finish — suitable for dry or protected interior environments

Compatibility

Designed as a standard 5/16-18 UNC cup point set screw for use in any application requiring a headless fastener with square drive and fractional inch threading.

Installation Notes

Install using the correct square drive bit or key to avoid rounding the socket. Ensure the mating component is properly aligned before tightening. Power down or de-energize any equipment before servicing assemblies that contain set screws. Do not exceed the torque capacity of Grade 2 steel fasteners in high-load or high-vibration applications where a higher material grade may be required.
