Value Collection 409137BR Set Screw 3/4-10 X 4 in Cup Point

Product Description

The VALUE COLLECTION 409137BR is a square-head cup point set screw engineered for mechanical fastening applications where a recessed, flush, or below-surface fastener is required. Manufactured from Grade 2 steel with a bright, uncoated finish, this set screw features a 3/4-10 UNC thread and measures 4 inches in length under head. The cup point geometry bites into the mating surface to resist rotation and axial movement, making it a reliable choice for shaft-collar, gear-hub, and fixture-holding applications. At approximately 0.1 pounds, it is sized for medium-duty industrial use and is sold in multiples of 10.

This set screw is suited for general industrial, mechanical, and MRO applications where a square-drive tool engagement is preferred for high-torque installation. Typical install scenarios include securing collars to shafts, locking hubs in position, and anchoring mechanical components where a protruding fastener head is not acceptable. The 3/4-10 UNC thread standard ensures compatibility with standard tapped holes produced to inch-fractional specifications.

Key Features

• Cup point geometry bites into mating surface for strong resistance to rotation and axial load
• Square head drive allows high-torque installation with a standard square wrench or socket
• 3/4-10 UNC thread conforms to standard inch-fractional thread specifications
• Grade 2 steel construction suitable for general-purpose mechanical fastening
• Bright, uncoated finish — no added coating thickness to affect thread tolerance
• 4-inch length under head accommodates deeper engagement in thick hubs or collars

Compatibility

Designed as a general-purpose replacement or service fastener for any tapped hole conforming to 3/4-10 UNC inch-fractional thread standards in industrial and mechanical assemblies.

Installation Notes

Installation is typically performed by a machinist or mechanical technician using a square-drive wrench or socket sized for the fastener head. De-energize and lock out any rotating machinery before servicing shaft collars, hubs, or other driven components. Ensure the mating tapped hole is clean and free of debris before threading to avoid cross-threading or galling. Torque to the value specified by the equipment manufacturer for the given application and material.
