  • Integrated flange design with 1 5/8" diameter distributes load evenly, eliminating need for separate washers
  • Superior torque transmission through external hex drive and standard hex nut profile for secure fastening
  • Reliable coarse threading with UNC 3/4"-10 specification resists vibration loosening in heavy-duty applications
  • Precision thread fit meeting Class 2B standards ensures consistent engagement and assembly efficiency
  • Robust dimensional profile featuring 1" height and 1 1/4" width for enhanced structural integrity
  • Full regulatory compliance with RoHS 3 and REACH standards for safe industrial usage

Professional Applications & Engineering Value

This heavy-duty flange nut delivers critical engineering advantages through its 18-8 stainless steel composition and integrated flange design. The corrosion-resistant properties make it ideal for outdoor equipment, marine applications, and chemical processing facilities where environmental exposure degrades ordinary fasteners. The UNC coarse threading combined with Class 2B thread fit provides excellent vibration resistance in machinery, construction equipment, and transportation systems. The substantial 1 5/8" flange diameter creates superior bearing surface distribution, preventing surface damage while eliminating separate washer requirements. This external hex drive configuration ensures maximum torque application during installation, maintaining joint integrity under extreme operational stresses.

Specification Summary & Compliance

Manufactured to precise dimensional standards including 1 5/8" flange diameter and 0.25" flange thickness. Thread specifications conform to UNC 3/4"-10 coarse thread with Class 2B thread fit tolerance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international environmental and safety standards for industrial components.
