S-90043A034 7/16"-14 Square Nuts

Key Features & Benefits at a Glance

• Superior holding power with coarse UNC threading that resists loosening under vibration and heavy loads
• Exceptional durability provided by high-strength steel construction for long service life in demanding environments
• Easy installation and removal with a 3/4" external square drive that offers superior tool grip and torque transmission
• Reliable thread engagement ensured by Class 2B thread fit for consistent performance and reduced cross-threading risk
• Versatile industrial compatibility with right-hand thread direction and standard UNC 7/16"-14 sizing
• Confident global sourcing with full compliance to RoHS 3 and REACH environmental regulations
• Optimized wrenching surface from the square nut design that prevents rotation during assembly

Professional Applications & Engineering Value

This heavy-duty steel square nut delivers critical engineering solutions for industrial assembly challenges. The 7/16"-14 UNC coarse thread provides excellent engagement in softer materials and faster installation compared to fine threads, while the external square drive design allows for high-torque application with standard wrenching tools. Manufactured from durable steel, this component maintains integrity under extreme vibration and load conditions commonly found in machinery, construction equipment, and automotive applications. The Class 2B thread fit ensures consistent mating with Class 2A bolts, reducing assembly time and preventing thread damage. These industrial square nuts are particularly valuable in applications where a flush surface isn't required but maximum holding strength is essential.

Specification Summary & Compliance

This square nut features 7/16"-14 UNC coarse threads with Class 2B thread fit per ASME/ANSI standards, ensuring precise dimensional accuracy and reliable performance. The nut measures 3/4" in width and 3/8" in height with right-hand thread direction. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making this component suitable for global industrial applications requiring environmental compliance.
