S-93839A031 3/8"-16 ASME B18.2.2 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional strength and durability with Grade 8 steel construction, ensuring reliable performance in high-stress industrial applications.
• Superior corrosion resistance provided by zinc yellow-chromate plating, extending the nut's lifespan in harsh or outdoor environments.
• Precise and secure fit due to Class 2B thread fit and UNC coarse threads, minimizing the risk of loosening under vibration or load.
• Space-saving thin profile (7/32" height) allows for use in tight or confined assemblies without compromising strength.
• Easy installation and removal with external hex drive design, compatible with standard wrenches for efficient maintenance.
• Compliance with ASME B18.2.2 standards guarantees consistent quality, dimensional accuracy, and interchangeability.
• Right-hand thread direction ensures straightforward assembly in common mechanical systems, reducing installation errors.

Professional Applications & Engineering Value

This Grade 8 heavy-duty thin hex nut is engineered to address critical challenges in demanding industrial settings, such as machinery, automotive, and construction assemblies. The zinc yellow-chromate-plated steel material offers excellent protection against rust and corrosion, which is vital for equipment exposed to moisture or chemicals. With 3/8"-16 UNC coarse threads and a Class 2B thread fit, it provides a secure, vibration-resistant connection that maintains integrity under dynamic loads. The thin profile (7/32" height) is ideal for space-constrained applications, allowing engineers to design compact yet robust systems. Manufactured to ASME B18.2.2 specifications, this nut ensures precise dimensions and reliable performance, reducing downtime and maintenance costs in professional environments.

Specification Summary & Compliance

This hex nut features a 3/8"-16 UNC coarse thread with Class 2B thread fit for consistent engagement and ease of assembly. Dimensions include a width of 9/16" and height of 7/32", adhering to ASME B18.2.2 standards for dimensional accuracy and quality. The zinc yellow-chromate plating on steel provides corrosion resistance, and the nut meets common industry requirements for heavy-duty fasteners, though specific RoHS or REACH compliance should be verified per batch. Designed for use in inch-system applications, it ensures reliable performance in mechanical and structural assemblies.
