Value Collection R56000562 Hex Socket Cap Screw 4-40 Unc

Product Description

The VALUE COLLECTION R56000562 is a hex socket cap screw designed for precision fastening in applications that demand corrosion resistance and dimensional accuracy. Threaded 4-40 UNC with a 5/8-inch length under head, this screw is driven by a 5/32-inch hex (Allen) key. It is manufactured from 316-grade stainless steel, which offers superior resistance to chlorides, moisture, and chemical exposure compared to standard 18-8 stainless. Typical users include maintenance technicians, mechanical assemblers, and field service professionals working on equipment where a reliable, corrosion-resistant fastener is required.

This screw is suited for light-duty mechanical assemblies, instrument panels, enclosures, and equipment housings where a 4-40 UNC thread pattern is specified. The low-profile socket cap head allows installation in recessed or tight clearance locations where a hex wrench or Allen driver can access the fastener. It is appropriate for both indoor and outdoor assemblies where stainless steel material grade is a specification requirement.

Key Features

• 4-40 UNC thread for compatibility with standard inch-series tapped holes
• 5/8-inch length under head suits moderate-depth fastening applications
• 5/32-inch hex drive for use with standard Allen keys or hex bit drivers
• 316 stainless steel construction provides enhanced corrosion and chloride resistance
• Socket cap head profile allows installation in confined or countersunk locations

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any application specifying a 4-40 UNC thread with a 5/8-inch length under head and a 5/32-inch hex drive.

Installation Notes

Installation is performed with a 5/32-inch hex key or Allen-style bit driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not exceed the torque rating appropriate for 4-40 stainless fasteners as specified by the equipment manufacturer. When installing in dissimilar metals, consider the potential for galvanic interaction with the 316 stainless material.
