Value Collection 409155BR Set Screw 1-8x5 Cup Point Steel

Product Description

The VALUE COLLECTION 409155BR is a 1-8 x 5 inch cup point set screw used to secure components onto shafts, collars, and other assemblies without a protruding head. Manufactured from Grade 2 steel with a bright uncoated finish, this fastener uses a square drive and features a cup point tip that bites into the mating surface to resist rotation and axial movement. The UNC thread standard ensures broad compatibility with standard inch-series tapped holes. It is sold individually and is suited for general mechanical assembly work in industrial, commercial, and trade applications.

This set screw is a standard inch-series fastener used in a wide range of mechanical assembly and maintenance tasks. Common applications include securing pulleys, gears, collars, and hubs to shafts in HVAC equipment, motors, pumps, and general machinery. The cup point design is well suited for applications where moderate holding force is needed without permanently marking a hardened shaft surface. Installation is handled by machinists, maintenance technicians, and trade professionals working on mechanical drive systems and equipment assemblies.

Key Features

• Cup point tip provides positive gripping contact on shaft surfaces
• Square drive allows high torque input with standard square-bit drivers
• Grade 2 steel construction suitable for general-duty mechanical fastening
• Bright uncoated finish for use in dry or low-corrosion environments
• UNC thread standard for compatibility with standard inch-series tapped holes
• Full 5 inch length accommodates deep-set or thick collar installations

Compatibility

Designed as a general-purpose inch-series set screw for use in any standard 1-8 UNC tapped hole requiring a cup point headless fastener.

Installation Notes

Installation requires a square-bit driver sized to match the drive recess. Ensure the mating tapped hole is clean and threads are free of debris before driving the screw. Always de-energize and lock out any equipment before servicing components such as pulleys, collars, or hubs. Do not exceed the torque capacity appropriate for Grade 2 steel fasteners at this thread size.
