• Superior Corrosion Resistance: Zinc alloy material provides excellent durability against rust and environmental degradation, extending service life in demanding industrial conditions.
• High Mechanical Strength: Withstands up to 150 in-lbs breaking torque, offering reliable performance under significant vibrational and load stresses.
• Standardized Thread Compatibility: 3/8"-16 UNC coarse thread with Class 2B fit ensures easy installation and consistent engagement with standard male fasteners.
• Convenient External Hex Drive: Allows for straightforward installation and removal using common tools, while maintaining tamper-proof characteristics post-installation.
• Regulatory Compliance Assurance: Meets RoHS 3 and REACH environmental standards, guaranteeing safe use in regulated industries and global markets.
• Optimized Dimensions: 3/4" width and 37/64" height provide a compact yet robust profile, suitable for space-constrained assemblies without compromising strength.

Professional Applications & Engineering Value

Engineered for maximum security applications, this tamper resistant nut addresses critical needs in public infrastructure, machinery guarding, and access control systems where unauthorized tampering poses safety or operational risks. The zinc alloy construction combats corrosion in outdoor or harsh industrial environments, while the UNC coarse thread and Class 2B thread fit ensure rapid assembly and vibration resistance. Its external hex drive facilitates installation with standard wrenches, yet the tamper-resistant feature activates once seated, making it ideal for permanent or semi-permanent fastening in transportation, utility, and manufacturing equipment where reliability and compliance are non-negotiable.

Specification Summary & Compliance

This nut features a 3/8"-16 UNC coarse thread with Class 2B thread fit per standard inch-system specifications, ensuring dimensional accuracy and interchangeability. Manufacturing adheres to industry norms for external hex drive fasteners, with precise controls on width (3/4") and height (37/64"). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances and supporting use in environmentally conscious industrial applications.
