Value Collection 409116BR Set Screw 5/8-11 X 2 in Cup Point

Product Description

The VALUE COLLECTION 409116BR is a 5/8-11 UNC cup point set screw designed for mechanical fastening applications where a flush or below-surface installation is required. Manufactured from Grade 2 steel with a bright uncoated finish, this set screw measures 2 inches in length and uses a square drive. It is intended for use in collars, hubs, pulleys, and similar mechanical assemblies where the cup point bites into the mating shaft to resist rotation and axial movement. Machinists, millwrights, and maintenance technicians are the primary installers of this fastener in industrial and general mechanical settings.

This set screw is suited for light- to medium-duty clamping applications in shaft-and-collar assemblies. The cup point geometry provides a defined bite into soft or hardened shaft material, offering reliable holding force without requiring a flat on the shaft. The square drive allows for installation with a square-key wrench or bit in tight or recessed locations. Typical applications include conveyor components, fan hubs, sprockets, and general machinery collars in both residential mechanical systems and light industrial equipment.

Key Features

• 5/8-11 UNC thread size for compatibility with standard inch-series tapped holes
• Cup point geometry bites into shaft surface to resist rotation and axial movement
• Square drive allows installation in recessed or tight-clearance locations
• Grade 2 steel construction suitable for light- to medium-duty clamping loads
• Bright uncoated finish — no coating buildup affecting thread fit
• 2-inch length under head for deep engagement in thick collars or hubs

Compatibility

Designed as an OEM-style replacement or standard-stock set screw for shaft collars, hubs, pulleys, and mechanical assemblies using 5/8-11 UNC tapped holes.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a square-key wrench or square-drive bit. De-energize and lock out all rotating equipment before installing or removing set screws. Do not exceed the torque capacity of the Grade 2 steel fastener — avoid impact drivers on hardened or precision assemblies. Confirm thread engagement depth meets design requirements before applying load.
