S-93839A815 3/8"-24 ASME B18.2.2 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional strength and reliability with Grade 8 classification, ensuring high tensile performance for heavy-duty and high-vibration applications.
• Superior corrosion resistance provided by the zinc yellow-chromate plating, extending service life in harsh or outdoor industrial environments.
• Space-saving thin profile (7/32" height) allows for use in confined spaces where standard nuts may not fit, without compromising strength.
• Precise and secure thread engagement with Class 2B thread fit and UNF fine thread (3/8"-24), reducing the risk of cross-threading and ensuring consistent clamping force.
• Broad compatibility and standardization through compliance with ASME B18.2.2, guaranteeing interchangeability and reliability in assembly lines.
• Easy installation and removal with an external hex drive (9/16" width), offering a firm grip for standard wrenches and reducing assembly time.
• Right-hand thread design for straightforward, intuitive fastening in common industrial and machinery applications.

Professional Applications & Engineering Value

This Grade 8 thin hex nut is engineered to address critical challenges in demanding sectors such as automotive, machinery, and structural assemblies. Its zinc yellow-chromate-plated steel construction provides a robust barrier against rust and chemical exposure, making it ideal for outdoor equipment or humid conditions. The UNF fine thread (3/8"-24) and Class 2B thread fit ensure tight, vibration-resistant connections, minimizing loosening in dynamic loads. By adhering to ASME B18.2.2 standards, it delivers consistent performance in precision applications, from engine components to conveyor systems, enhancing operational safety and reducing maintenance downtime.

Specification Summary & Compliance

This nut features a 3/8"-24 UNF fine thread with Class 2B thread fit for precise tolerance, and complies with ASME B18.2.2 manufacturing specifications. Dimensions include a width of 9/16" and height of 7/32" for a thin profile. The material is zinc yellow-chromate-plated steel, and it meets common industry requirements for performance and safety, though specific RoHS or REACH declarations should be verified per batch.
