Value Collection 872033PR Hex Socket Cap Screw 4-40 Unc

Product Description

The VALUE COLLECTION 872033PR is a 4-40 UNC hex socket cap screw designed for precision fastening in light-duty mechanical and structural assemblies. It features a 3/32-inch hex drive socket and measures 1/4 inch in length under the head. Constructed from alloy steel with a zinc-plated finish, this screw delivers solid corrosion resistance in typical indoor and controlled-environment applications. The fully threaded shank provides maximum thread engagement along the entire fastener length. Machinists, maintenance technicians, and assembly professionals working on small-format equipment, instruments, or enclosures will find this fastener a reliable choice.

This screw is suited for use in precision equipment assembly, instrument panels, electronic enclosures, and light mechanical fixtures where a 4-40 UNC thread is specified. The zinc plating makes it appropriate for dry or mildly humid indoor environments. This fastener is sold in minimum order quantities of 100 units per order, making it practical for shop stock or production-line use. It is a common choice in applications governed by ASME B18.8 and ASTM A574 standards.

Key Features

• 4-40 UNC thread size for precision small-format fastening applications
• 3/32-inch hex socket drive for standard Allen wrench or hex key installation
• 1/4-inch length under head with fully threaded shank for maximum thread engagement
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Zinc-plated finish provides corrosion resistance in indoor environments
• Conforms to ASME B18.8 dimensional standards

Compatibility

Designed as a standard 4-40 UNC hex socket cap screw suitable for tapped holes conforming to 4-40 UNC thread specifications in mechanical assemblies, instrument enclosures, and light-duty structural applications.

Installation Notes

Installation is performed using a 3/32-inch hex key or Allen wrench. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not exceed the torque capacity appropriate for a 4-40 alloy steel screw in the mating material. Follow applicable ASME or facility standards for fastener installation procedures.
