Value Collection BT-1420-750-SS Set Screw 1/4-20

Product Description

The VALUE COLLECTION BT-1420-750-SS is a 1/4-20 x 3/4-inch set screw with a soft tip point, manufactured from Grade 18-8 stainless steel with a brass tip insert. Set screws of this type are used to secure components onto shafts or within assemblies without the need for a protruding head. The hex drive allows installation with a standard hex key, and the soft brass tip protects the mating surface from damage during tightening. This fastener suits applications where corrosion resistance and surface protection are both required.

This set screw is well-suited for light industrial, mechanical, and trade service applications where a headless fastener must bear against a shaft or surface without marring it. The UNC/UNF thread standard compatibility gives it broad fitment across common threaded assemblies. Typical use cases include set-screw collars, shaft couplings, pulleys, and adjustment mechanisms found in HVAC equipment, plumbing assemblies, and general mechanical installations.

Key Features

• 1/4-20 thread size with 3/4-inch thread length for standard UNC and UNF threaded applications
• Grade 18-8 stainless steel construction provides corrosion resistance in wet or humid environments
• Soft brass tip protects shaft and mating surface finishes during installation and under load
• Hex drive accepts standard hex keys for controlled, precise tightening
• Headless profile sits flush within the threaded bore for compact, snag-free installation

Compatibility

Designed as a standard 1/4-20 UNC/UNF set screw for use in threaded bores across a wide range of mechanical assemblies requiring a soft-tip, surface-protecting fastener.

Installation Notes

Installation is performed with a properly sized hex key; using an undersized key risks rounding the drive socket. Ensure the threaded bore is clean and free of debris before installation. Do not overtighten, as the brass tip is softer than steel and can deform under excessive torque. This fastener is intended for installation by qualified technicians familiar with torque requirements for the specific assembly.
