Value Collection 409141BR Set Screw 7/8-9 X 2 in Cup Point

Product Description

The VALUE COLLECTION 409141BR is a cup point set screw designed for secure fastening in mechanical assemblies where a flush or recessed fastener is required. This screw features a 7/8-9 UNC thread and a 2-inch length, measured from under the head. Made from Grade 2 alloy steel, it delivers reliable holding strength in shaft-to-hub connections, collars, and similar applications. The cup point bites into the mating surface to resist rotation and axial movement. Licensed trades and machine technicians install these during assembly or field repair of rotating equipment and structural components.

This set screw suits residential and commercial mechanical applications where a square-drive, cup-point fastener is specified. Common install scenarios include securing shaft collars, pulleys, gears, and sprockets to rotating shafts. The 7/8-9 UNC thread is a standard coarse-thread designation, making this screw compatible with a wide range of threaded hardware applications in industrial, HVAC, and mechanical service environments. Sold individually with a minimum order quantity of 10 units.

Key Features

• 7/8-9 UNC coarse thread for broad compatibility with standard threaded assemblies
• 2-inch length measured under head for precise fitment in deep-set applications
• Cup point geometry bites into mating surface to resist rotation and axial displacement
• Grade 2 alloy steel construction provides solid holding strength for mechanical fastening
• Square drive type for positive tool engagement and high torque transfer
• Fractional inch sizing aligns with standard imperial hardware specifications

Compatibility

Designed as a standard-duty replacement or stock fastener for mechanical assemblies requiring a 7/8-9 UNC cup point set screw with a 2-inch length and square drive.

Installation Notes

Installation is typically performed by millwrights, mechanical technicians, or HVAC service technicians during equipment assembly or repair. Power down and lock out all associated equipment before installing or replacing set screws in rotating assemblies. Use a correctly sized square drive tool to achieve full engagement and avoid cam-out. Do not overtighten, as this may damage the mating shaft surface or strip the thread engagement.
