S-92174A690 1 1/2"-12 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance from durable brass construction, ideal for harsh industrial environments
• Precise fine thread engagement with Class 2B fit ensures secure, vibration-resistant connections
• Space-saving thin profile (27/32" height) allows installation in tight clearance applications
• Easy installation and removal with standard 2 1/4" external hex drive using common tools
• Reliable performance in inch-system assemblies with UNF fine threading for enhanced load distribution
• Environmental compliance meets RoHS 3 and REACH standards for global industrial use
• Right-hand threading compatibility with standard UNF components for simplified inventory management

Professional Applications & Engineering Value

This 1 1/2"-12 UNF thin hex nut delivers critical engineering advantages where space constraints and corrosion resistance are paramount. The brass material provides excellent conductivity and non-sparking properties, making it ideal for electrical panels, marine hardware, and chemical processing equipment. The Class 2B thread fit maintains consistent clamping force while accommodating minor misalignments in assembly. With its fine UNF threading, this nut distributes stress more evenly than coarse-thread alternatives, reducing the risk of stripping in soft materials or thin-walled components. The thin profile design solves clearance issues in compact machinery and electronic enclosures where standard nuts would interfere with adjacent components.

Specification Summary & Compliance
