Value Collection 592107PR Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION 592107PR is a hex socket cap screw designed for precision fastening applications where reliable clamping force and corrosion resistance are required. This screw features a 5-40 UNC thread size with a 5/8-inch length under head and is driven by a 3/32-inch hex key. Constructed from 18-8 austenitic stainless steel (Grade A2), it offers strong resistance to rust and oxidation in both indoor and outdoor environments. The fully threaded shank provides maximum thread engagement along the entire length. Manufactured to ASME/ANSI B18.3 and ASTM F837 standards, this fastener is suited for use in applications demanding dimensional consistency and material traceability.

This socket cap screw is commonly used in mechanical assemblies, instrumentation, light machinery, and enclosure hardware where a low-profile cap head and internal hex drive are preferred over external hex configurations. Its 18-8 stainless steel construction makes it appropriate for environments with exposure to moisture or mild chemicals. Sold in packages of one unit with a minimum order quantity of 100 units, this screw is typically sourced by maintenance technicians, machine builders, and contractors needing a reliable, standards-compliant fastener in volume.

Key Features

• 5-40 UNC thread size for fine-pitch engagement in small fastening applications
• 5/8-inch length under head for adequate grip and clamping depth
• 3/32-inch internal hex drive for use with standard Allen wrenches or hex keys
• Fully threaded shank maximizes thread engagement along the full length
• 18-8 austenitic stainless steel (Grade A2) provides corrosion and oxidation resistance
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed as an OEM-style and general-purpose replacement socket cap screw for applications requiring a 5-40 UNC thread, 5/8-inch length under head, and 3/32-inch hex drive in stainless steel.

Installation Notes

Installation is performed with a 3/32-inch hex key or Allen wrench; ensure the drive tool is fully seated before applying torque to avoid cam-out and fastener damage. Power down or de-energize any equipment before accessing fastener locations in electrical or mechanical enclosures. Follow applicable ASME or industry torque guidelines for 5-40 stainless fasteners and avoid over-tightening, which can cause thread stripping in stainless steel due to galling. Apply an anti-galling compound or thread lubricant when installing stainless-to-stainless assemblies to reduce the risk of seizing.
