A six-sided internally threaded fasteners which is both thicker and wider across the flats than a same-sized finished hex net. This is the strongest of all comparably graded nuts because of its greater length of thread engagement and greater resistance to dilation (widening or stretching)

• Grade 2H nuts are recommended for use with bolts in high-pressure and high-temperature service. Grade 2H nuts are are heat treated by quenching in a liquid medium from a temp above the transformation temp
• Rockwell C24 - C38 / 150,000 psi proof load / Hot dip galvanizing is generally the most effective way to apply a sufficient thickness of zinc to threaded fasteners for zinc to serve as a corrosion protection in harsh enviroments.
• Thread Size-Pitch: 5/8"-11
