Value Collection 872045PR Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION 872045PR is a fully threaded hex socket cap screw designed for precision fastening applications in metalworking, machinery assembly, and fabrication. The fastener measures 3/8 inches in length under the head and accepts a 3/32 inch hex drive. Manufactured from alloy steel with a zinc-plated finish, the 872045PR meets ASME B18.8 and ASTM A574 standards, making it suitable for applications that require a reliable, corrosion-resistant internal-drive fastener. These cap screws are sold individually but carry a minimum order quantity of 100 units per order.

This screw is suited for light-gauge assemblies, precision instruments, electronics enclosures, and mechanical sub-assemblies where a low-profile socket head and fine 5-40 UNC thread engagement are required. The zinc plating provides basic corrosion resistance appropriate for indoor or protected environments. Machinists, millwrights, and assembly technicians working on close-tolerance components will find the 5-40 UNC thread pitch and alloy steel construction appropriate for demanding fastening tasks.

Key Features

• 5-40 UNC thread for fine-pitch engagement in precision assemblies
• 3/8 inch length under head for standard socket cap screw applications
• 3/32 inch hex drive size for use with standard Allen keys or hex drivers
• Fully threaded shank for maximum thread engagement across the full fastener length
• Alloy steel construction meets ASTM A574 mechanical requirements
• Zinc-plated finish provides corrosion resistance for indoor and protected installations

Compatibility

Designed as a standard replacement or stock fastener for assemblies specifying a 5-40 UNC hex socket cap screw per ASME B18.8 dimensional standards.

Installation Notes

Installation requires a 3/32 inch hex key or socket driver. Ensure mating tapped holes are clean and free of debris before driving. Do not exceed the rated engagement torque for the thread size and base material. Follow applicable mechanical assembly standards and inspect the fastener seating after installation to confirm full head contact.
