Value Collection 307140BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 307140BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, maintenance, and industrial equipment work. It features a 5/8-11 UNC thread, a 2.75-inch length under head, and is partially threaded to allow controlled engagement in through-hole and tapped-hole applications. Manufactured from alloy steel and finished with a black oxide coating, the fastener delivers solid corrosion resistance and a clean appearance suited for demanding environments. The 0.5-inch hex drive accepts standard hex keys and Allen wrenches. It meets ASTM A574 specifications for high-strength socket head cap screws.

This screw is used in a wide range of industrial and mechanical applications where a high-strength, recessed-drive fastener is required. Common install scenarios include machinery frames, brackets, hydraulic assemblies, and equipment housings. The 5/8-11 UNC thread is a coarse-thread designation widely used in general industrial fastening. The partial threading is typical for fasteners that clamp two members together without threading through the full grip length. Licensed millwrights, machinists, maintenance technicians, and mechanical contractors are the typical end users.

Key Features

• 5/8-11 UNC coarse thread for broad compatibility with standard tapped holes
• 2.75-inch length under head for adequate grip in medium-depth assemblies
• Partially threaded shank for controlled clamping without full-length engagement
• Alloy steel construction meets ASTM A574 high-strength socket head cap screw standard
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 0.5-inch hex socket drive accepts standard hex keys for installation in confined spaces

Compatibility

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

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical maintenance technicians using a calibrated torque wrench and the appropriate 0.5-inch hex key or Allen-drive socket. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not exceed the rated torque for the thread size and material class as defined in ASTM A574 and applicable engineering specifications. Inspect threads for damage before use and discard any fastener with crossed, stripped, or deformed threads.
