Value Collection NT-51624-375-AS Set Screw 5/16-24

Product Description

The VALUE COLLECTION NT-51624-375-AS is a Grade 8 alloy steel set screw with a soft nylon tip, designed for applications requiring secure, non-marring clamping force on shafts, collars, and similar components. This fastener uses a hex drive and features a 5/16-24 thread size with a length of 3/8 inches, placing it in the fine-thread UNF category while also conforming to UNC thread standards. The nylon tip protects the mating surface from damage during tightening, making it a common choice in mechanical assemblies where surface finish and part integrity are priorities. Installers working in machinery, HVAC equipment, and industrial assemblies regularly specify this type of fastener.

This set screw is suited for use in residential and light commercial mechanical assemblies, including motor shaft retention, pulley and collar securing, and similar clamping applications. The Grade 8 alloy steel construction provides high tensile strength suitable for demanding mechanical environments. It is commonly installed during equipment assembly, maintenance, or field repair where a non-marring hold point is required without damage to the contact surface.

Key Features

• Grade 8 alloy steel construction for high tensile strength
• Nylon soft tip protects mating shaft or surface from deformation
• Hex drive for standard hex key installation
• 5/16-24 fine thread for precise engagement and strong hold
• 3/8 inch thread length suits compact clamping applications
• Conforms to both UNF and UNC thread standards

Compatibility

Designed as a standard replacement or service fastener for mechanical assemblies requiring a 5/16-24 set screw with a soft nylon tip point and hex drive.

Installation Notes

This fastener is typically installed by mechanical technicians, HVAC service professionals, or maintenance personnel using a standard hex key or Allen wrench. Always de-energize and lock out equipment before accessing rotating assemblies or shaft components. Do not over-tighten, as excessive torque can deform or displace the nylon tip and reduce clamping effectiveness. Verify thread engagement and seat the screw per equipment manufacturer specifications.
