S-95195A270 1 1/8"-7 Hex Nuts

Key Features & Benefits at a Glance

• Corrosion-resistant performance with 18-8 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Secure left-hand thread engagement prevents unintentional loosening in rotating machinery and specialized equipment where reverse-direction forces are present.
• Reliable coarse thread design ensures faster assembly and reduced cross-threading risk compared to fine-thread alternatives.
• Precision Class 2B thread fit guarantees consistent mating with male threads, minimizing play and vibration-induced failures.
• Standard external hex drive allows for high-torque installation using common wrenches and sockets, streamlining maintenance workflows.
• Heavy-duty 1 1/8"-7 UNC sizing provides robust clamping force for high-load structural connections and machinery assemblies.
• RoHS 3 compliance meets stringent environmental regulations, ensuring safe use in regulated industries and global supply chains.

Professional Applications & Engineering Value

This left hand thread hex nut delivers critical engineering value in applications where standard right-hand threads would loosen under counter-clockwise rotational forces. Manufactured from 18-8 stainless steel, it provides excellent corrosion resistance for chemical processing equipment, marine hardware, and food machinery where moisture and corrosive agents are present. The coarse UNC thread with Class 2B fit enables rapid installation in high-vibration environments like conveyor systems, agricultural machinery, and automotive assemblies, reducing assembly time while maintaining joint integrity. The combination of left-hand threading and external hex drive makes it indispensable for securing components on rotating shafts, mixer blades, and press screws where reverse-thread locking is essential for operational safety.

Specification Summary & Compliance

This hex nut features 1 1/8"-7 UNC coarse threads with Class 2B thread fit per ASME B18.2.2 standards, ensuring dimensional accuracy and interchangeability. The left-hand thread direction follows industry-accepted threading conventions for specialized fastening requirements. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, confirming restriction of hazardous substances. Physical dimensions include 1 11/16" width across flats and 31/32" height, conforming to standard hex nut profiles for consistent tool engagement.
