Value Collection 604425BR Set Screw 5/8-11 X 1 in Grade 8

Product Description

The VALUE COLLECTION 604425BR is a cone point set screw designed for mechanical fastening applications where a secure, non-removable hold is required. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and hardness suitable for demanding industrial and trade environments. It features a 5/8-11 UNC thread and measures 1 inch in overall length. The 5/16-inch hex drive accepts a standard hex key for installation and adjustment. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards, confirming dimensional and material compliance for professional use.

This set screw is used in shaft-to-hub assemblies, collars, pulleys, gears, and similar mechanical connections where the cone point digs into the mating surface to resist rotation and axial movement. It is appropriate for both light industrial and heavy-duty applications. Typical installers include millwrights, maintenance mechanics, HVAC equipment technicians, and general trade professionals working on rotating equipment or mechanical assemblies.

Key Features

• Cone point geometry bites into mating shaft surface to resist rotation and axial movement
• Grade 8 alloy steel construction provides high tensile and proof load strength
• 5/8-11 UNC thread for compatibility with standard inch-series tapped holes
• 5/16-inch hex drive accepts common hex keys and Allen drivers
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Sold individually, allowing single-piece procurement for replacement or repair use

Compatibility

Designed as a standard inch-series set screw for use in any 5/8-11 UNC tapped hole requiring a cone point fastener in mechanical assemblies such as shaft collars, hubs, and pulleys.

Installation Notes

Installation is performed with a 5/16-inch hex key. Ensure the tapped hole is clean and free of debris before threading the screw in by hand to confirm proper thread engagement. Apply appropriate thread-locking compound if vibration resistance beyond the cone point bite is required. Always de-energize or lock out rotating equipment before servicing any shaft or hub assembly.
