Value Collection BT-1428-250-SS Set Screw 1/4-28

Product Description

The VALUE COLLECTION BT-1428-250-SS is a 1/4-28 UNF hex-drive set screw with a soft tip point, manufactured from 18-8 stainless steel with a brass tip insert. At 0.25 inches in thread length, this fastener is designed to lock shafts, collars, pulleys, and other components in position without marring the mating surface. The brass tip compresses against the shaft to provide holding force while protecting the workpiece finish. Plumbers, HVAC technicians, electricians, and general mechanical trades reach for this style of set screw when axial positioning and surface protection are both required.

This set screw is suited for light industrial, mechanical, and trade applications where a non-galling, corrosion-resistant fastener is needed. The 18-8 stainless steel construction resists rust and mild chemical exposure, making it appropriate for damp environments such as pump assemblies, HVAC equipment, and plumbing fixture components. The 1/4-28 UNF thread provides fine-pitch engagement well suited to thin-walled collars and precision-adjusted assemblies.

Key Features

• 1/4-28 UNF fine-pitch thread for precise axial adjustment
• Soft tip point with brass tip insert protects shaft and mating surfaces from marring
• 18-8 stainless steel body resists corrosion in damp or mildly corrosive environments
• Hex drive for standard hex key installation in tight spaces
• 0.25-inch thread length suits thin collars, hubs, and compact assemblies

Compatibility

Designed as a standard 1/4-28 UNF soft-tip set screw for use in any application requiring a hex-drive, brass-tipped fastener of this thread size and length.

Installation Notes

Installation requires a hex key sized to the socket drive; ensure the correct key size is fully seated before applying torque to avoid rounding the socket. De-energize or lock out any rotating equipment before accessing shaft collars or set screw locations. The brass soft tip is intended to grip the shaft surface without damaging it, so avoid over-tightening, which can deform the tip and reduce holding performance. Follow applicable mechanical and trade codes for fastener installation in safety-critical assemblies.
