Professional Applications & Engineering Value
This 1/4"-20 UNC Grade 2H steel hex nut delivers exceptional engineering value through its unique extra-wide thin profile that addresses critical industrial challenges. The expanded bearing surface distributes clamping forces more effectively, preventing material deformation and maintaining joint integrity in high-vibration applications. The coarse thread design enables rapid installation while resisting loosening under dynamic loads, making it ideal for assembly lines and maintenance operations. Manufactured from ASTM Grade 2H steel, this fastener provides reliable performance in structural frameworks, heavy machinery, and transportation equipment where Class 2B thread fit ensures consistent engagement without galling or cross-threading issues. The external hex drive accommodates standard wrenches for efficient installation in confined spaces.
Specification Summary & Compliance
This hex nut maintains precise Class 2B thread fit tolerances per ASME B18.2.2 standards with 1/4"-20 UNC coarse threads and right-hand thread direction. Manufacturing complies with ASTM Grade 2H strength requirements, featuring dimensions of 1/2" width and 11/64" height. The product fully meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance standards for hazardous substance restrictions.
