Value Collection NT-1420-250-SS Set Screw 1/4-20 Ss

Product Description

The VALUE COLLECTION NT-1420-250-SS is a 1/4-20 x 1/4 inch hex-drive set screw with a nylon soft tip point, manufactured from Grade 18-8 stainless steel. Set screws of this type are used to secure a component — such as a collar, pulley, gear, or bushing — against a shaft without a protruding head. The nylon tip protects the mating surface from scoring or galling, making this fastener well suited for applications where shaft finish or surface integrity must be preserved. The hex socket drive accepts a standard hex key for installation and removal in tight or recessed locations. The all-thread 1/4 inch length is measured as full thread length.

This set screw is used across HVAC, plumbing, electrical, and mechanical assembly applications wherever a low-profile, non-marring shaft lock is required. Common installations include fan blade hubs, motor shaft collars, valve handles, and equipment mounting assemblies. Grade 18-8 stainless steel provides corrosion resistance suitable for both indoor and light outdoor environments. The UNC and UNF thread standard compatibility broadens its use across a wide range of threaded bores and pre-tapped assemblies in residential and commercial equipment.

Key Features

• Nylon soft tip protects shaft surfaces from scoring or damage during tightening
• Grade 18-8 stainless steel construction offers reliable corrosion resistance
• Hex socket drive accepts standard hex key for installation in confined spaces
• Full 1/4 inch thread length provides solid engagement in standard-depth tapped holes
• Compatible with both UNC and UNF thread standards in 1/4-20 bores
• Headless design sits flush with or below the surface for clearance-critical assemblies

Compatibility

Designed as a standard 1/4-20 UNC hex-drive soft tip set screw for use in any pre-tapped 1/4-20 bore requiring a non-marring shaft retention fastener.

Installation Notes

Installation should be performed by a qualified technician using a correctly sized hex key to avoid rounding the socket drive. Ensure the mating bore is clean and free of debris before threading in the fastener. Do not exceed the torque capacity of the nylon tip, as overtightening can deform or displace the tip material and reduce holding force. Always de-energize and lock out any equipment before servicing components secured by set screws.
