Value Collection 409221BR Set Screw 5/8-11 X 5.5in Cup Point

Product Description

The VALUE COLLECTION 409221BR is a cup point set screw designed for mechanical clamping and locking applications in industrial and trade settings. It features a 5/8-11 UNC thread with a 5-1/2 inch length measured under the head. Manufactured from Grade 2 alloy steel, it delivers solid holding strength for shaft-to-hub connections, collars, and mechanical assemblies. The square drive accepts a standard square key wrench for installation. This screw is sold individually with a minimum order quantity of 10 pieces.

This set screw is used in a wide range of mechanical assembly applications including motor shaft collars, gear hubs, pulleys, and couplings. It is suited for residential and commercial mechanical systems wherever a headless fastener is required to bear against a shaft or seat in a drilled hole. Machinists, millwrights, and maintenance technicians commonly install this type of fastener during equipment assembly and repair work.

Key Features

• Cup point tip provides a defined bite into shaft material for positive locking
• 5/8-11 UNC thread form for compatibility with standard imperial tapped holes
• 5-1/2 inch length accommodates deep-threaded engagement requirements
• Square drive reduces cam-out risk during high-torque installation
• Grade 2 alloy steel construction for reliable mechanical strength
• Fractional inch sizing for straightforward imperial measurement compatibility

Compatibility

Designed as a standard UNC fractional inch set screw suitable for any threaded assembly requiring a 5/8-11 tapped hole and a cup point headless fastener.

Installation Notes

Installation is performed using a properly sized square key wrench. Ensure the mating tapped hole is clean and free of debris before threading the screw in by hand to verify engagement. Power down and de-energize any rotating equipment before accessing shaft collars or mechanical assemblies. Do not overtighten beyond the torque rating of the mating component material.
