Professional Applications & Engineering Value
This extra-wide thin hex nut delivers critical engineering advantages in demanding applications. The 18-8 Stainless Steel composition provides exceptional corrosion resistance, solving common failure points in chemical processing, marine, and outdoor industrial settings. The 1 1/8"-7 UNC coarse thread configuration ensures rapid installation while maintaining secure fastening, particularly valuable in assembly line operations and structural frameworks. The extra-wide thin profile (1 13/16" width) distributes clamping force over a larger area, preventing material deformation in soft metals or composite materials. This combination of chemical resistance, efficient installation, and superior load distribution makes it ideal for heavy machinery, structural steel connections, and industrial equipment requiring reliable, long-term fastening solutions.
Specification Summary & Compliance
Manufactured to precise Class 2B thread fit standards with UNC coarse threading (1 1/8"-7) and right-hand thread direction. Dimensions include 1 13/16" width and 39/64" height. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions adherence for industrial fastener applications.
