Value Collection 409154BR Cup Point Set Screw Alloy Steel

Product Description

The VALUE COLLECTION 409154BR is a square-drive, cup point set screw used to secure components to shafts, collars, and assemblies without a protruding head. Manufactured from Grade 2 alloy steel, it offers reliable holding strength in mechanical and industrial applications. The cup point digs into the mating surface to resist rotation and axial movement. Thread size is 1-8 UNC with a length of 4.5 inches measured under the head. Licensed tradespeople and millwrights install this type of fastener in power transmission, conveyor, and general mechanical assembly work.

This set screw is suited for use in mechanical assemblies where a flush or recessed fastener is required. The square drive style is common in industrial maintenance environments where higher torque input is needed compared to hex socket drives. Typical applications include shaft collars, sprockets, pulleys, gears, and similar rotating components in both light industrial and heavy mechanical settings. It is sold individually and is well suited for replacement or repair work where a single fastener is needed.

Key Features

• Cup point geometry bites into mating surface for strong rotational and axial resistance
• Square drive allows high torque input during installation
• Grade 2 alloy steel construction for durability in mechanical service
• UNC thread standard ensures broad compatibility with standard tapped holes
• Headless design sits flush or below surface for clearance-sensitive assemblies
• Sold as a single unit for precise quantity ordering in repair applications

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies requiring a 1-8 UNC cup point set screw with a 4.5-inch length.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a square drive bit or wrench of the appropriate size. Ensure the mating shaft or surface is clean and free of debris before driving the screw to full engagement. De-energize and lock out any rotating equipment before servicing fasteners on shafts or collars, following OSHA lockout-tagout procedures. Do not exceed the rated torque capacity of the drive recess to avoid rounding the socket.
