Value Collection 603441BR Set Screw 5/8-18 X 5/8 in Flat Point Grade 8

Product Description

The VALUE COLLECTION 603441BR is a flat point set screw designed for secure, non-projecting fastening applications in mechanical assemblies. Manufactured from Grade 8 alloy steel, it delivers high tensile strength and hardness suited to demanding industrial and trade environments. The 5/8-18 UNF thread provides fine-pitch engagement, and the 5/8-inch overall length keeps the fastener compact within the host component. Drive is a 5/16-inch hex socket, compatible with standard hex keys and Allen drivers. This fastener is built to ASME/ANSI B18.3 and ASTM F912 standards, making it appropriate for applications where dimensional and mechanical traceability is required.

Flat point set screws like the 603441BR are commonly used to lock collars, hubs, pulleys, and gears onto shafts without damaging the shaft surface. They are found in HVAC blower assemblies, pump drive shafts, and general mechanical equipment across residential and light commercial installations. The fine UNF thread offers precise torque control during installation. This part is typically installed by millwrights, HVAC technicians, and maintenance mechanics working on rotating equipment where shaft retention and minimal surface deformation are priorities.

Key Features

• Flat point tip minimizes shaft surface damage during and after installation
• Grade 8 alloy steel construction provides high hardness and tensile strength
• 5/8-18 UNF fine-pitch thread for precise engagement and torque control
• 5/16-inch hex socket drive compatible with standard hex keys
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards
• Compact 5/8-inch overall length suits tight hub and collar installations

Compatibility

Designed as an OEM-style replacement or standard-supply set screw for mechanical assemblies requiring a 5/8-18 UNF flat point fastener in Grade 8 alloy steel.

Installation Notes

Installation is performed with a 5/16-inch hex key or Allen driver. Always de-energize and lock out rotating equipment before servicing shaft-mounted components. Apply thread-locking compound if specified by the equipment manufacturer to prevent back-out under vibration. Do not exceed the torque range appropriate for Grade 8 alloy steel fasteners of this thread size as specified by the governing equipment documentation.
