S-95140A111 1/4"-20 Hex Nuts

Key Features & Benefits at a Glance

• High-strength Grade 5 steel construction ensures reliable performance in heavy-duty applications, resisting deformation under high loads.
• Left-hand (reverse) thread design provides secure fastening in rotating assemblies where standard right-hand threads may loosen, enhancing safety.
• UNC coarse threading with Class 2B fit offers quick assembly and reduced cross-threading risks, saving time in industrial settings.
• External hex drive style allows for maximum torque application using common tools, improving installation efficiency.
• RoHS 3 and REACH compliance guarantees adherence to environmental and safety regulations, supporting sustainable procurement practices.
• Standard inch measurements (1/4"-20 thread, 7/16" width, 7/32" height) ensure compatibility with existing equipment and simplify inventory management.
• Durable steel material provides excellent corrosion resistance and long service life in demanding environments.

Professional Applications & Engineering Value

This Grade 5 steel left hand hex nut is engineered to address critical challenges in industrial and mechanical systems where reverse rotation or vibration could compromise fastener integrity. Featuring UNC coarse threads and a Class 2B thread fit, it ensures precise engagement and reduces the risk of stripping in high-stress applications such as machinery, automotive assemblies, and conveyor systems. The external hex drive design allows for high torque application, making it ideal for maintenance and manufacturing tasks that require robust, reliable fastening solutions. By utilizing left-hand threading, it provides a secure lock in scenarios where standard nuts might loosen, thereby minimizing downtime and enhancing operational safety in heavy-duty environments.
