Value Collection 409150BR Set Screw Cup Point Alloy Steel

Product Description

The VALUE COLLECTION 409150BR is a cup point set screw manufactured from Grade 2 alloy steel with a square drive. It is designed to secure a component — such as a collar, sprocket, pulley, or gear — against a shaft by applying concentrated clamping force through its cup-shaped tip. The fastener uses a 1-8 UNC thread and measures 2.5 inches in length, measured under the head. At 0.02 pounds, it is a compact fastener suited for medium-duty mechanical assemblies. Installation requires a square drive tool sized for this fastener head. Licensed mechanics, millwrights, and maintenance technicians are the primary installers.

This set screw is used in industrial, commercial, and mechanical maintenance applications where a shaft-mounted component must be held in a fixed position. Common install scenarios include motor shaft assemblies, conveyor components, and mechanical drive systems. The cup point geometry bites into the shaft surface to resist rotational slippage. The UNC thread standard makes it compatible with standard inch-based tapped holes. Minimum order quantity is 10 pieces per order.

Key Features

• Cup point tip concentrates clamping force for positive shaft engagement
• Square drive head for positive torque transfer with standard square drive tools
• Grade 2 alloy steel construction for strength in mechanical assembly applications
• 1-8 UNC thread standard for compatibility with standard inch-based tapped holes
• 2.5-inch length measured under head for deeper thread engagement
• Fractional inch sizing for use in standard U.S. mechanical assemblies

Compatibility

Designed as a standard UNC inch-series set screw for use in any tapped hole conforming to 1-8 UNC thread specifications in industrial and mechanical maintenance applications.

Installation Notes

Installation is typically performed by millwrights, maintenance technicians, or mechanical assemblers using a correctly sized square drive tool. De-energize and lock out any equipment before installing or removing set screws per OSHA lockout/tagout requirements. Do not overtighten — apply torque per the fastener grade rating for the specific assembly. Ensure the tapped hole is clean and free of debris before threading the screw.
