Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, this 12-point screw addresses critical fastening challenges in machinery assembly, structural frameworks, and equipment manufacturing. The black-oxide alloy steel construction provides essential corrosion protection while maintaining the 170,000 psi tensile strength required for high-stress connections. The external 12-point drive enables high-torque installation without cam-out, particularly valuable in confined spaces where socket access is limited. The flange design eliminates the need for separate washers, distributing clamp load effectively across joined surfaces. With UNC coarse threads and Class 2A thread fit, this fastener ensures rapid assembly and reliable performance in vibration-prone environments, making it ideal for construction equipment, automotive systems, and industrial machinery where partial threading provides optimal strength in shear-critical applications.

Specification Summary & Compliance

This 12-point screw features 7/16"-14 UNC coarse threads with Class 2A thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy and interchangeability. The manufacturing process adheres to industry specifications for alloy steel fasteners, with Rockwell C38 hardness and 170,000 psi tensile strength verification. The black-oxide surface treatment provides corrosion resistance while maintaining compliance with industrial fastener requirements. The product meets applicable standards for heavy-duty industrial screws and is suitable for applications requiring reliable performance under significant mechanical stress.
