Value Collection 604422BR Set Screw 5/8-11 X 3/4 in Cone Point

Product Description

The VALUE COLLECTION 604422BR is a cone point set screw designed for secure, permanent fastening applications where the point must bite into or indent a mating surface to resist rotation and axial movement. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile and torsional strength suited to demanding mechanical assemblies. The 5/16-inch hex drive accepts a standard hex key for installation and removal. With a 5/8-11 UNC thread and an overall length of 3/4 inches, this set screw is dimensioned for precision fit in pre-tapped bores. It meets ASME/ANSI B18.3 and ASTM F912 standards, confirming dimensional and mechanical compliance. Maintenance technicians, millwrights, and mechanical contractors are the typical installers.

This set screw is suited for use in shaft-to-hub connections, collars, pulleys, sprockets, and similar mechanical assemblies across industrial and commercial equipment. The cone point geometry creates a positive indent in the shaft surface, providing high holding force in fixed-position applications. It is appropriate for use wherever a UNC 5/8-11 tapped bore is present and a cone point drive configuration is specified by the assembly design.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Cone point tip bites into mating surface for strong, vibration-resistant holding
• 5/8-11 UNC thread for compatibility with standard tapped bores
• 5/16-inch hex drive for use with standard hex keys and allen wrenches
• Overall length of 3/4 inches for precise engagement depth
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards

Compatibility

Designed as an OEM-style replacement or service fastener for any mechanical assembly specifying a 5/8-11 UNC cone point set screw with a 5/16-inch hex drive and 3/4-inch overall length.

Installation Notes

Installation is performed by millwrights, maintenance technicians, or mechanical contractors using a 5/16-inch hex key. Ensure the tapped bore is clean and free of debris before threading the fastener. Apply appropriate thread-locking compound if specified by the equipment manufacturer to prevent loosening under vibration. Never overtighten; doing so may damage the shaft surface beyond the intended cone-point indent or strip the tapped bore.
