Value Collection BT1420-750-AS25 Set Screw 1/4-20 X 3/4 in 25pk

Product Description

The VALUE COLLECTION BT1420-750-AS25 is a 1/4-20 UNC hex-drive set screw with a soft tip point, manufactured from Grade 8 alloy steel with a brass tip insert. Set screws of this type are used to lock a component — such as a collar, gear, pulley, or hub — onto a shaft without a traditional bolt head. The hex socket drive accepts a standard hex key for installation and removal. The soft brass tip makes contact with the mating shaft surface, gripping securely while reducing the risk of marring or damaging the shaft finish. This package contains 25 pieces.

This set screw is suited for general mechanical and industrial assembly applications where a headless fastener is required to secure rotating or stationary components to a shaft. The 1/4-20 UNC thread and 3/4-inch thread length make it a common choice in light machinery, HVAC equipment assemblies, motor shaft collars, and similar mechanical hardware applications. Installation is performed by trades and maintenance technicians working on mechanical assemblies requiring precise component positioning and retention.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard American inch-series tapped holes
• 3/4-inch thread length provides adequate engagement depth for secure shaft locking
• Grade 8 alloy steel construction delivers high tensile and torsional strength
• Soft brass tip protects shaft surfaces from scoring or deformation during tightening
• Hex socket drive accepts standard hex keys for easy installation in confined spaces
• Pack of 25 pieces supports production, maintenance, and service inventory needs

Compatibility

Designed as a standard 1/4-20 UNC soft-tip set screw suitable for use in any tapped hole conforming to 1/4-20 UNC thread specifications where a headless, shaft-locking fastener with a brass tip is required.

Installation Notes

Installation is typically performed by mechanical technicians or maintenance personnel using a calibrated hex key or hex bit driver. Always de-energize and lock out any machinery before installing or adjusting set screws on rotating shaft assemblies, following applicable LOTO procedures. Do not overtighten, as excessive torque can shear the screw or damage the brass tip. Ensure the mating tapped hole is clean and free of debris before threading the screw in.
