Value Collection 409152BR Set Screw Cup Point Alloy Steel

Product Description

The VALUE COLLECTION 409152BR is a cup point set screw used to secure a component onto a shaft or within a housing without a projecting head. Manufactured from Grade 2 alloy steel, this screw features a 1-8 UNC thread size and measures 3-1/2 inches in length, with the length measured under the head. The square drive socket accepts a standard square-drive key for installation or removal. This type of fastener is commonly installed by millwrights, maintenance technicians, and mechanical contractors in industrial and commercial equipment assemblies where a flush or recessed fastening point is required.

Cup point set screws like the 409152BR are used in a wide range of mechanical applications including shaft collars, pulleys, gears, sprockets, and couplings. The cup point geometry bites into the mating surface to resist rotation and axial movement under load. This makes the fastener well suited for moderate to heavy-duty clamping applications where a permanent or semi-permanent hold is needed. The alloy steel construction provides strength appropriate for industrial machinery and equipment maintenance environments.

Key Features

• Cup point geometry provides firm bite into mating shaft surface to resist slippage
• Square drive socket for positive torque transfer during installation
• 1-8 UNC thread form for use in standard unified coarse thread tapped holes
• 3-1/2 inch length measured under head accommodates deeper engagement applications
• Grade 2 alloy steel construction for industrial-duty tensile strength
• Headless design sits flush or below surface for tight clearance installations

Compatibility

Designed as a standard UNC set screw for use in any tapped hole with a 1-8 thread specification requiring a cup point, headless fastener in alloy steel.

Installation Notes

Installation requires a square-drive key sized to match the socket of this fastener. De-energize and lock out any equipment before installing or removing set screws from rotating shaft assemblies. Ensure the mating tapped hole is clean and free of debris before threading the fastener. Follow applicable mechanical and equipment manufacturer torque guidelines for the assembly.
