Value Collection 837425BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 837425BR is a 5/8-11 UNC hex socket cap screw designed for high-strength bolted connections in industrial and mechanical assemblies. The fastener measures 3 inches in length under the head and is partially threaded, making it well suited for applications where a smooth shank is required to bear shear loads or act as a shoulder. It is driven with a 1/2-inch hex key and is manufactured from alloy steel with a zinc-plated finish for corrosion resistance. Machinists, millwrights, and maintenance technicians commonly install this type of fastener in fabricated steel structures, machine frames, and equipment housings.

This cap screw is appropriate for general industrial, manufacturing, and maintenance applications where a coarse-thread 5/8-inch fastener is specified. The 5/8-11 UNC thread form is a standard coarse-pitch designation commonly found in structural and mechanical assemblies across commercial and industrial settings. The zinc finish provides a base level of corrosion protection suitable for interior and sheltered environments. The fastener meets ASTM B695 standards for zinc coatings applied to fasteners.

Key Features

• 5/8-11 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• 3-inch length under head with partial threading to preserve a smooth shank for shear-load applications
• 1/2-inch hex drive for high torque input using a standard hex key or T-handle
• Alloy steel construction for strength in demanding mechanical assemblies
• Zinc-plated finish meeting ASTM B695 for corrosion resistance in sheltered environments

Compatibility

Designed as a standard 5/8-11 UNC hex socket cap screw suitable for use in any tapped hole or nut conforming to the UNC coarse-thread series at that diameter.

Installation Notes

Installation is typically performed by a machinist, millwright, or maintenance technician using a 1/2-inch hex key or Allen-drive tool. Always ensure mating threads are clean and free of debris before driving the fastener. Do not exceed the recommended torque for the fastener grade and material being clamped. Inspect threads for damage before installation and replace any fastener that shows signs of galling or distortion.
