Value Collection 101633BR Set Screw 5/8-11 X 3 in Cup Point

Product Description

The VALUE COLLECTION 101633BR is a cup point set screw used to secure components such as collars, hubs, and pulleys onto shafts without a protruding head. Manufactured from Grade 8 alloy steel, it delivers high tensile strength suitable for demanding mechanical and industrial applications. The 5/8-11 UNC thread and 3-inch overall length make it appropriate for medium-to-large shaft assemblies. Drive is a 5/16-inch hex socket, engaged with a standard hex key or Allen driver. This fastener meets ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards, ensuring consistent thread fit and hardness across installations.

Cup point set screws like the 101633BR are used across mechanical power transmission assemblies, manufacturing equipment, HVAC drive components, and general industrial machinery. The cup point geometry bites into the shaft surface to resist rotation and axial movement. This fastener is typically installed by millwrights, maintenance mechanics, and HVAC technicians working on blower wheel assemblies, fan hubs, sheaves, and pulley systems where a flush, headless retention method is required.

Key Features

• 5/8-11 UNC thread for secure engagement in standard coarse-thread tapped holes
• 3-inch overall length provides deep thread engagement for high-load applications
• Cup point geometry bites into shaft surface to resist axial and rotational movement
• Grade 8 alloy steel construction for high tensile and torsional strength
• 5/16-inch hex drive compatible with standard hex keys and Allen drivers
• Meets ASME/ANSI B18.3 and ASTM F912 standards for dimensional accuracy and mechanical properties

Compatibility

Designed as a standard UNC coarse-thread cup point set screw for use in any tapped 5/8-11 socket set screw hole requiring a 3-inch overall length fastener per ASME/ANSI B18.3 specifications.

Installation Notes

Installation is performed with a 5/16-inch hex key torqued to the assembly specification defined by the equipment manufacturer. Always de-energize and lock out the drive system before accessing shaft-mounted components. Avoid over-tightening, which can deform the shaft seat or strip the threaded hole. Follow applicable ASME or equipment OEM guidelines for set screw torque and positioning relative to keyways.
