Value Collection 307146BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 307146BR is a 5/8-11 UNC hex socket cap screw designed for high-strength fastening in industrial, mechanical, and structural applications. It features a 4-inch length under the head with partial threading, giving it the clamping strength needed for bolted joint assemblies where full thread engagement is not required along the full shank. The drive is a 1/2-inch internal hex socket, compatible with standard Allen keys and hex bit drivers. Constructed from alloy steel with a black oxide finish, this fastener meets ASTM A574 specifications for mechanical and dimensional requirements.

This cap screw is suited for machine assembly, tooling, fixture building, and general industrial fastening where a high-strength, low-profile socket head is required. The partial thread design makes it appropriate for clamping two surfaces together without thread engagement in the grip zone. It is commonly used in manufacturing facilities, maintenance shops, and field service applications across a wide range of industries.

Key Features

• 5/8-11 UNC thread for standard coarse-pitch fastening
• 4-inch length under head with partial threading for optimal clamping in bolted assemblies
• 1/2-inch hex socket drive for use with Allen wrenches and hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection

Compatibility

Designed as an OEM-style replacement or service fastener for any application requiring a 5/8-11 UNC partially threaded hex socket cap screw conforming to ASTM A574.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 1/2-inch hex key or socket bit driver. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or threadlocker as required by the joint specification. Torque to the value specified by the equipment manufacturer or applicable engineering standard for 5/8-11 alloy steel fasteners.
