Value Collection 307142BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 307142BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and structural connections. The screw features a 5/8-11 UNC thread size and a 3-inch length under the head, with partial threading along the shank. Drive engagement is via a 1/2-inch hex socket. Constructed from alloy steel with a black oxide finish coating, this fastener resists corrosion in moderate environments and meets ASTM A574 specifications for high-strength socket cap screws. Machinists, millwrights, and maintenance technicians commonly install this type of fastener in industrial and commercial settings.

This cap screw is suited for use in machine bases, tooling fixtures, equipment frames, and general structural assemblies where a flush or recessed fastener profile is required. The partially threaded shank allows for precise clamping load and is appropriate for through-bolt and tapped-hole applications. The 5/8-11 UNC coarse thread pitch offers reliable engagement in steel and cast iron tapped holes, making it a common choice for heavy equipment maintenance and fabrication work.

Key Features

• 5/8-11 UNC coarse thread for strong engagement in steel and cast iron
• 3-inch length under head with partial threading on shank
• 1/2-inch hex drive socket for standard hex key or socket driver installation
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish coating provides mild corrosion resistance and reduces light reflection

Compatibility

Designed as a standard ASTM A574 hex socket cap screw for use in any 5/8-11 UNC tapped hole or through-hole assembly requiring a 3-inch length under head.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 1/2-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before installation. Apply thread lubricant or thread-locking compound as required by the application specification. Always follow torque guidelines specified in the applicable engineering documentation for 5/8-11 ASTM A574 fasteners.
