Value Collection NT-1420-750-SS Set Screw 1/4-20 X 3/4 in

Product Description

The VALUE COLLECTION NT-1420-750-SS is a 1/4-20 x 3/4 inch set screw with a soft nylon tip point, manufactured from Grade 18-8 stainless steel. The nylon tip protects the mating surface or shaft from marring and damage during tightening, making it a reliable choice when surface finish or component integrity matters. Drive engagement is via a hex socket. This fastener is used across HVAC, plumbing, electrical, and general mechanical assemblies where a locking or positioning screw is needed without permanent surface damage. Maintenance technicians and assembly professionals working with threaded fasteners in corrosion-prone environments will find the 18-8 stainless construction well suited for the application.

This set screw is appropriate for residential and commercial mechanical applications where UNC or UNF 1/4-20 threaded holes are present. Common installation scenarios include motor shaft collars, fan hubs, valve handles, and panel or bracket positioning hardware. The nylon soft tip is especially useful in settings where vibration could loosen a standard cup-point set screw, or where the clamped component must remain unmarked. The 18-8 stainless steel grade provides solid corrosion resistance in damp or chemical-exposure environments typical in HVAC equipment rooms, mechanical closets, and poolside installations.

Key Features

• Soft nylon tip point prevents marring or gouging of shaft and mating surfaces
• Grade 18-8 stainless steel construction for corrosion resistance in wet or humid environments
• Hex socket drive for standard hex key installation and removal
• 1/4-20 thread size compatible with UNC and UNF threaded holes
• 3/4 inch thread length provides positive engagement depth in standard collar and hub applications

Compatibility

Designed as an OEM-style replacement or drop-in fastener for any application requiring a 1/4-20 UNC or UNF threaded set screw with a soft tip point in a standard hex socket drive configuration.

Installation Notes

Installation requires a properly sized hex key or hex bit driver matched to the socket size of this set screw. Power down any rotating equipment and lock out or tag out per applicable safety procedures before replacing or adjusting set screws on motor shafts or drive components. Do not overtighten, as the nylon tip is designed for controlled clamping force and excessive torque may deform the tip. Ensure threads in the receiving hole are clean and free of debris before installation.
