S-99612A186 1"-14 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh environments
• Reliable left-hand thread security prevents loosening in counter-rotating applications and specialized machinery
• Precise Class 2B thread fit ensures smooth assembly and consistent clamping force in demanding applications
• Fine threading (1"-14) provides improved vibration resistance and better load distribution compared to coarse threads
• Grade 5 strength rating delivers excellent mechanical performance for heavy-duty industrial applications
• Thin hex profile design offers space-saving advantages while maintaining full fastener integrity
• Full regulatory compliance with RoHS 3 and REACH standards for safe use across regulated industries

Professional Applications & Engineering Value

This left-hand thread hex nut addresses critical engineering challenges in applications where standard right-hand threads would naturally loosen due to rotational forces. The zinc-plated steel construction provides essential corrosion protection for industrial equipment, machinery, and outdoor applications exposed to moisture and environmental elements. The fine threading (1"-14) and Class 2B thread fit ensure precise engagement with mating components, reducing the risk of cross-threading while maintaining consistent clamping force in high-vibration environments. The thin hex profile is particularly valuable in space-constrained assemblies where standard nuts would interfere with adjacent components, making it ideal for automotive, manufacturing, and specialized equipment requiring left-hand thread security and reliable performance under demanding conditions.

Specification Summary & Compliance

This Grade 5 zinc-plated steel thin hex nut features 1"-14 left-hand fine threading with Class 2B thread fit per UNS standards, ensuring precise dimensional accuracy and reliable performance. The external hex drive design provides secure tool engagement for efficient installation. Manufactured to meet Grade 5 strength requirements with dimensions of 1-1/2" width and 35/64" height. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, making it suitable for regulated industrial applications worldwide.
