• Reliable coarse UNC thread (7/16"-14) with Class 2A fit ensures consistent engagement and reduces cross-threading risks.
• Optimized for varied clamping needs with a partially threaded 4" length and 1 1/8" minimum thread length for precise joint control.
• Compliance with major industry standards including ASME B18.2.1, guaranteeing dimensional accuracy and interchangeability.
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance, meeting global regulatory requirements.

Professional Applications & Engineering Value

This 7/16"-14 UNC hex head screw is engineered to address critical challenges in industrial assembly, such as vibration loosening and material degradation. The 18-8 Stainless Steel provides excellent resistance to rust and chemicals, making it suitable for outdoor machinery, marine equipment, and food processing plants where moisture is a concern. Its coarse thread design ensures quick assembly and robust holding power in softer materials or when frequent disassembly is required. The partially threaded shank concentrates clamping force precisely, preventing joint failure in structural frameworks, conveyor systems, and heavy-duty manufacturing fixtures. By combining high tensile strength with standardized external hex drive compatibility, this fastener reduces downtime and maintenance costs, delivering consistent performance in rigorous B2B environments.

Specification Summary & Compliance

This product adheres to Class 2A thread fit tolerances as per UNC standards, ensuring precise thread engagement and interchangeability. Manufacturing conforms to ASME B18.2.1 specifications for dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances for safe and sustainable use in global markets.
