S-95140A143 1/2"-13 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional strength for demanding applications with Grade 5 steel construction, ensuring reliable performance under high stress.
• Secure, reverse-thread locking capability provided by the left-hand thread direction, preventing loosening in rotating machinery.
• Easy and quick installation with a standard external hex drive profile and coarse UNC threading for efficient assembly.
• Precise and consistent thread engagement due to the Class 2B thread fit, reducing the risk of cross-threading and ensuring a tight seal.
• Compliance with strict environmental regulations, being RoHS 3 and REACH compliant for safe use in regulated industries.
• Durable and corrosion-resistant steel material, offering long service life in industrial, automotive, and construction environments.
• Standard inch sizing (1/2"-13) for broad compatibility with existing equipment and fasteners, simplifying procurement and replacement.

Professional Applications & Engineering Value

This Grade 5 steel hex nut with left-hand coarse threading is engineered to address critical challenges in high-vibration and rotational systems. Its reverse thread direction is essential for applications where standard right-hand threads would naturally loosen, such as in specific machinery, automotive components, and conveyor systems. The UNC coarse thread and Class 2B fit provide excellent resistance to stripping and galling, even in frequent disassembly scenarios. Made from robust steel, it ensures high tensile strength and durability, making it ideal for heavy-duty industrial and construction uses where reliability is paramount. The external hex drive allows for straightforward installation with common tools, reducing labor time and enhancing operational efficiency in maintenance and assembly lines.

Specification Summary & Compliance

This nut features a 1/2"-13 UNC coarse thread with a Class 2B thread fit, ensuring dimensional accuracy and smooth assembly. It adheres to standard inch measurement specifications, with a width of 3/4" and height of 7/16". The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for environmental and health standards. The Grade 5 strength classification guarantees consistent performance in various demanding applications.
