S-2995T896 1/4"-20 Hex Nuts

Key Features & Benefits at a Glance

• Dual Thread Direction Convenience – Includes both left-hand and right-hand threaded jam nuts in one set, eliminating the need for separate purchases and simplifying inventory management for turnbuckle assemblies.
• Reliable Grade 2 Steel Construction – Manufactured from durable steel to provide consistent strength and resistance to deformation under typical industrial loads, ensuring long-term fastener integrity.
• Secure Class 2B Thread Fit – Precision UNC coarse threads offer excellent engagement and vibration resistance, reducing the risk of loosening in high-stress applications like turnbuckles.
• Standard External Hex Drive Design – Compatible with common wrenches for easy installation and removal, speeding up assembly and maintenance processes in industrial settings.
• Compact 7/16" Width & 5/32" Height Profile – Space-saving jam nut design allows for tight clearances while maintaining full thread contact, ideal for confined turnbuckle and linkage systems.
• Full RoHS 3 & REACH Compliance – Meets stringent environmental and safety regulations, ensuring suitability for global industrial supply chains without hazardous substance restrictions.
• Optimized for Turnbuckle Durability – Specifically engineered to withstand the alternating tension and rotational forces in turnbuckle applications, preventing thread stripping and assembly failure.

Professional Applications & Engineering Value

This Grade 2 steel hex jam nut set addresses critical challenges in turnbuckle and rigging systems where left-hand and right-hand threaded components must work in tandem to adjust tension reliably. The UNC coarse threading with Class 2B fit ensures rapid assembly and superior resistance to vibrational loosening, a common failure point in dynamic load environments. Made from robust steel, these external hex drive nuts maintain clamp load under cyclic stresses, while their compact standard hex profile (7/16" width) fits into tight spaces without sacrificing wrench accessibility. By providing both thread directions in a single, RoHS and REACH compliant package, this set reduces installation errors and inventory complexity for industrial maintenance, construction, and marine applications.

Specification Summary & Compliance

These 1/4"-20 UNC hex jam nuts adhere to Class 2B thread fit tolerances for consistent engagement and are manufactured in accordance with inch system standards. The set includes one left-hand and one right-hand threaded nut, each with a coarse thread spacing and dimensions of 7/16" width and 5/32" height. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations is confirmed, ensuring adherence to environmental and safety protocols for industrial fastener applications.
