Value Collection 409130BR Set Screw 3/4-10 X 1-3/4 in Cup Point

Product Description

The VALUE COLLECTION 409130BR is a 3/4-10 UNC alloy steel set screw with a cup point tip and square drive, sized at 1-3/4 inches in length measured under head. Cup point set screws are used to lock shafts, collars, and hubs in place by biting into the mating surface under torque. This Grade 2 alloy steel construction provides solid holding strength for general mechanical fastening applications. The square drive socket requires a matching square key for installation and removal. Tradespeople, millwrights, and maintenance mechanics commonly use this fastener in rotating equipment assemblies and shaft-collar connections.

This set screw is suited for residential and commercial mechanical assemblies where positive shaft retention is required. Typical applications include securing pulleys, sprockets, gears, and shaft collars to drive shafts. The cup point geometry concentrates clamping force at a small area, improving grip on smooth or lightly knurled shaft surfaces. The 3/4-10 UNC thread size fits standard tapped holes found in medium-to-heavy-duty machine components. Minimum order quantity is 10 pieces per order.

Key Features

• 3/4-10 UNC thread for compatibility with standard tapped collars and hubs
• Cup point tip concentrates holding force directly on the shaft surface
• Square drive socket for positive tool engagement during installation
• Grade 2 alloy steel construction for reliable mechanical holding strength
• 1-3/4 inch length measured under head for deep thread engagement

Compatibility

Designed as a standard replacement or stock fastener for mechanical assemblies requiring a 3/4-10 UNC cup point set screw with square drive.

Installation Notes

Installation is performed by threading the set screw into a pre-tapped hole using a square drive key of the correct size. De-energize and lock out all rotating equipment before servicing shaft-collar connections. Tighten to the torque specification listed in the equipment manufacturer's documentation. Do not substitute drive key sizes, as an improperly fitted key can damage the socket and prevent adequate torque application.
