Value Collection NT-1420-312-AS Set Screw 1/4-20 X 5/16 in

Product Description

The VALUE COLLECTION NT-1420-312-AS is a 1/4-20 x 5/16 inches soft tip set screw manufactured from Grade 8 alloy steel with a nylon tip insert. Set screws of this type are used to secure components to shafts or other mating surfaces without a protruding head. The hex drive socket accepts a standard hex key for installation and removal. The nylon tip protects the mating surface from marring or gouging, making this screw a preferred choice when shaft finish or part integrity must be preserved. This fastener follows UNC/UNF thread standards and is suited for general industrial and mechanical assembly applications.

This set screw is commonly used in mechanical assemblies where a flush or recessed fastener is required. Typical applications include securing pulleys, collars, gears, and similar components onto shafts in HVAC equipment, motors, pumps, and light industrial machinery. The soft nylon tip makes it appropriate for use on finished or coated shafts where a hardened cup-point set screw would cause surface damage. Installation is performed by technicians and machinists using a standard hex key or Allen wrench. This item is sold individually with a minimum order quantity of 10 units.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Nylon soft tip protects shaft and mating surfaces from damage during tightening
• Hex drive socket accepts standard Allen/hex key tools
• 1/4-20 UNC/UNF thread standard for broad compatibility with standard tapped holes
• Headless design sits flush or below the surface for clearance-critical installations
• 5/16 inch engaged thread length suitable for light to medium clamping loads

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for any application requiring a 1/4-20 x 5/16 inches hex socket soft tip set screw in Grade 8 alloy steel with a nylon tip.

Installation Notes

Installation requires a properly sized hex key to avoid rounding the drive socket. Ensure the tapped hole is clean and free of debris before threading in the screw. Do not overtighten, as excessive torque can shear the nylon tip or strip the threads in softer mating materials. Shut down and de-energize any equipment before servicing assemblies that incorporate this fastener.
