Value Collection 307136BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 307136BR is a fully threaded hex socket cap screw designed for high-strength fastening in mechanical, structural, and industrial applications. Built to ASTM A574 specifications, this screw features a 5/8-11 UNC thread size and measures 2.25 inches under the head. It is manufactured from alloy steel with a black oxide coating that provides moderate corrosion resistance and reduces light reflection in finished assemblies. Installation requires a 0.5-inch hex drive. This fastener is suited for machine shops, maintenance technicians, fabricators, and general industrial trades working with metal assemblies that demand reliable clamping force.

This cap screw is commonly used in precision machinery, jigs and fixtures, structural steel connections, and general industrial assembly where a recessed drive head and full thread engagement are required. The 5/8-11 UNC thread pitch is a standard coarse thread, making it compatible with a wide range of tapped holes and threaded inserts in carbon steel, aluminum, and cast iron components. It is appropriate for both original equipment manufacturing and maintenance-and-repair operations.

Key Features

• ASTM A574 rated alloy steel construction for high tensile strength fastening
• Fully threaded 5/8-11 UNC coarse thread for maximum thread engagement
• 2.25-inch length under head accommodates medium-depth fastening applications
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• 0.5-inch hex socket drive for use with standard hex keys and socket drivers

Compatibility

Designed as a standard ASTM A574 hex socket cap screw for use in any application requiring a 5/8-11 UNC fully threaded fastener with a 0.5-inch hex drive.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians using a calibrated torque wrench and a properly sized 0.5-inch hex key or driver bit. Ensure the mating threaded hole is clean, properly tapped, and free of debris before driving. De-energize and lock out any machinery before installing or removing fasteners in live equipment per applicable OSHA lockout/tagout procedures. Do not exceed the rated torque for the thread size and material class to avoid galling or fastener failure.
