S-90083A230 5/8"-11 Hex Nuts

Key Features & Benefits at a Glance

• Left-hand threading provides secure fastening in applications where standard right-hand threads could loosen from counter-rotational forces
• Thin profile design (3/8" height) offers space-saving advantages in compact assemblies without compromising strength
• Grade 2 steel construction delivers reliable strength and durability for general industrial applications
• Class 2B thread fit ensures smooth assembly and consistent performance with standard mating components
• External hex drive allows for easy installation and removal with common wrench tools
• UNC coarse threading provides faster assembly and reduced cross-threading risk compared to fine threads
• RoHS 3 & REACH compliance guarantees environmental safety and regulatory adherence for global industrial use

Professional Applications & Engineering Value

This left-hand thin hex nut addresses critical engineering challenges in applications where rotational forces naturally loosen standard fasteners. The 5/8"-11 UNC coarse thread configuration combined with Class 2B thread fit ensures reliable engagement in high-vibration environments such as rotating machinery, conveyor systems, and automotive components. The thin profile (3/8" height) makes it particularly valuable in space-constrained assemblies where standard hex nuts would be too bulky. Manufactured from Grade 2 steel, this nut maintains structural integrity while the external hex drive design accommodates standard wrenching tools for efficient maintenance. These features make it ideal for maintenance-intensive equipment, left-hand thread applications, and assemblies requiring frequent disassembly.

Specification Summary & Compliance

This inch system fastener features precise 5/8"-11 UNC coarse threads with Class 2B thread fit per ASME B1.1 standards, ensuring compatibility with standard mating components. The nut maintains dimensional accuracy with 15/16" width across flats and 3/8" height profile. Manufactured to industrial standards using Grade 2 steel, this product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting the latest environmental and safety regulations for industrial fasteners.
