Value Collection 837033PR Hex Socket Cap Screw 4-40 Unc

Product Description

The VALUE COLLECTION 837033PR is a hex socket cap screw designed for applications requiring a compact, high-strength threaded fastener. Built from alloy steel with a zinc-plated finish, it provides corrosion resistance in typical indoor and light-duty industrial environments. The screw features a 4-40 UNC thread and a 3/32 inch hex drive, making it compatible with standard hex keys and Allen wrenches. The 1/4 inch length under head and fully threaded shank allow secure clamping in thin or shallow-tapped assemblies. Machinists, maintenance technicians, and assembly professionals commonly use this fastener in precision equipment, electronic enclosures, and mechanical assemblies where a low-profile cap screw is needed.

This fastener is suited for light mechanical assemblies, instrument panels, electronic hardware, and similar applications that call for a 4-40 UNC thread form. The small drive size and full thread engagement make it practical in tight clearance areas. It meets ASTM B695 standards for zinc coating, making it appropriate for controlled environments where moderate corrosion resistance is required. Minimum order quantity is 100 pieces per order, sold as a package quantity of 1.

Key Features

• 4-40 UNC thread size for compatibility with standard tapped holes in light mechanical and electronic assemblies
• Fully threaded shank provides maximum thread engagement over the 1/4 inch length under head
• 3/32 inch hex socket drive accepts standard hex keys for installation in confined spaces
• Alloy steel construction delivers greater tensile strength than standard carbon steel fasteners
• Zinc-plated finish meets ASTM B695 for moderate corrosion resistance
• Minimum order quantity of 100 units supports production and maintenance stocking requirements

Compatibility

Designed as a standard 4-40 UNC hex socket cap screw for use in any application with a corresponding 4-40 UNC tapped hole requiring a 3/32 inch hex drive and a 1/4 inch length under head.

Installation Notes

Installation requires a 3/32 inch hex key or Allen driver. Verify the mating tapped hole is clean and free of debris before threading to avoid cross-threading the fine 4-40 UNC thread form. Do not apply excessive torque, as alloy steel screws at this size have relatively low torque thresholds. Follow applicable assembly specifications or equipment service documentation for proper installation procedure.
