Value Collection NT-1420-375-AS Set Screw 1/4-20 X 3/8 in

Product Description

The VALUE COLLECTION NT-1420-375-AS is a 1/4-20 x 3/8-inch soft tip set screw made from Grade 8 alloy steel with a nylon tip. Set screws are headless fasteners that thread fully into a tapped hole to apply clamping force against a shaft, surface, or component. This screw uses a hex drive and a soft nylon tip to grip without marring the mating surface. Electricians, millwrights, and mechanical installers use soft tip set screws in applications where surface damage to a shaft or finished part is not acceptable.

This set screw is suited for light industrial, mechanical, and electrical applications where a standard cup point or cone point would damage a polished or finished shaft. The nylon tip distributes load softly, making it a common choice for securing pulleys, collars, and knobs on shafts. Thread standard is UNC and UNF compatible at 1/4-20, and the thread length runs the full 3/8-inch body length.

Key Features

• Soft nylon tip protects shaft and mating surface from scoring or marring
• Grade 8 alloy steel body provides high tensile and proof load strength
• Hex drive accepts standard hex key or allen wrench
• 1/4-20 thread compatible with UNC and UNF tapped holes
• Full-thread body at 3/8 inches with no head protrusion

Compatibility

Designed as a standard 1/4-20 UNC/UNF soft tip set screw for use in any tapped hole or threaded collar requiring a 1/4-20 thread and 3/8-inch engagement length.

Installation Notes

Installation is performed using a hex key sized for the drive socket; ensure the key is fully seated before applying torque to avoid rounding the drive. Power down or de-energize any equipment before installing or adjusting set screws on rotating or driven shafts. Thread the screw by hand until snug before final tightening to confirm thread engagement and prevent cross-threading. Dispose of or replace the nylon tip if it shows deformation that would reduce holding force.
