Value Collection 409149BR Set Screw 1-8x2 in Cup Point Alloy Steel

Product Description

The VALUE COLLECTION 409149BR is a cup point set screw designed for secure, non-permanent fastening in mechanical assemblies. Manufactured from Grade 2 alloy steel, this fastener features a 1-8 UNC thread with a 2-inch length measured under the head. The square drive allows for high torque application without fastener damage during installation or removal. Cup point geometry bites into the mating surface to resist rotational and axial movement, making it well suited for shaft-to-hub connections, collars, and similar mechanical retention applications. Installed by machinists, millwrights, and maintenance technicians across industrial and commercial settings.

This set screw is appropriate for use in power transmission components including shaft collars, pulleys, sprockets, gears, and hubs where positive retention is required. The UNC thread standard ensures broad compatibility with standard fractional-inch tapped holes. Grade 2 alloy steel construction provides adequate hardness for general-purpose mechanical fastening in both light industrial and heavy-duty maintenance applications. Sold individually with a minimum order quantity of 10 units per order.

Compatibility

Designed as a general-purpose replacement or stock fastener for any assembly requiring a 1-8 UNC, 2-inch cup point set screw with a square drive in standard fractional-inch tapped holes.

Installation Notes

Set screws of this type are installed by machinists, millwrights, and maintenance technicians using a square-drive bit or key of the appropriate size. Always de-energize and lock out equipment before accessing shaft assemblies or drive components. Tighten to the appropriate torque for the application based on fastener grade and mating material. Do not reuse set screws that show deformation, thread damage, or point wear, as reduced clamping force may result in fastener failure.
