S-93350A554 3/8"-16 x 1 3/4" Coupling Nuts

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with zinc-flake coating, extending service life in harsh industrial environments
• Reliable thread engagement through Class 2B coarse UNC threading, ensuring secure connections in high-vibration applications
• Easy installation and removal with external hex drive design, compatible with standard wrenches for efficient maintenance
• Full-threaded construction provides maximum strength distribution across the entire 1 3/4" length for heavy-duty applications
• Standard right-hand threading offers compatibility with common industrial components and simplified assembly processes
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries
• Robust steel core material delivers high tensile strength and durability for demanding mechanical connections

Professional Applications & Engineering Value

This 3/8"-16 UNC coupling nut solves critical connection challenges in industrial assembly where extended reach between threaded rods or studs is required. The zinc-flake-coated steel construction provides superior corrosion protection compared to conventional plating, making it ideal for automotive, construction, and machinery applications exposed to moisture and chemicals. The Class 2B thread fit ensures consistent engagement without binding, while the coarse UNC threading maintains reliability in high-vibration environments where fine threads might loosen. The fully threaded design across its 1 3/4" length distributes mechanical stress evenly, preventing failure points in structural applications. This external hex coupling nut enables quick installation with common tools, reducing assembly time in production lines and maintenance scenarios.

Specification Summary & Compliance

This coupling nut features 3/8"-16 UNC coarse threading with Class 2B thread fit for precise dimensional accuracy. The standard profile measures 1 3/4" in length with a 5/8" width across flats for compatibility with standard tools. Manufactured from steel with zinc-flake coating and fully threaded right-hand design, the product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards for restricted substances.
