Value Collection 872355PR Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 872355PR is a hex socket cap screw designed for applications requiring a strong, recessed-drive fastener. Sized at 1/2-13 UNC with a 1-inch length under head, this screw is fully threaded and accepts a 3/8-inch hex drive. Constructed from alloy steel with a zinc-plated finish, it meets ASME B18.8 and ASTM A574 standards. This combination of material and coating provides mechanical strength and basic corrosion resistance suited for industrial, mechanical, and structural assemblies. Machinists, maintenance technicians, and assembly professionals install this type of fastener across a wide range of equipment and fixture applications.

This socket cap screw fits residential, commercial, and industrial assembly scenarios where a low-profile, high-strength fastener is needed in close quarters or counter-bored holes. The 1/2-13 UNC thread is a coarse-thread standard common in general mechanical and structural work. The zinc coating makes it suitable for indoor and light-duty applications where mild corrosion protection is required. It is sold in a minimum order quantity of 10 pieces per order.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard tapped holes
• 1-inch length under head for precise engagement depth in typical machine assemblies
• Fully threaded shank for maximum thread engagement along the full fastener length
• 3/8-inch hex socket drive for use with standard hex keys or socket drivers
• Alloy steel construction meets ASTM A574 for high tensile strength requirements
• Zinc-plated finish provides basic corrosion resistance for indoor and sheltered environments

Compatibility

Designed as an OEM-style and general-use replacement hex socket cap screw for any application requiring a 1/2-13 UNC, fully threaded, 1-inch-under-head socket cap screw conforming to ASME B18.8 and ASTM A574 standards.

Installation Notes

Installation is performed with a 3/8-inch hex key or socket driver. Always ensure the mating tapped hole is clean and free of debris before driving the fastener. Confirm the thread class and hole depth are compatible before installation to avoid cross-threading or bottoming out. Follow applicable fastener torque standards for 1/2-13 UNC alloy steel screws per your engineering specification or applicable code.
