2H-2HM nuts

2H nuts are used in high-temperature, high-pressure applications and conditions requiring high strength and durability, while 2HM nuts are used in connections with constant loads and lower strength requirements.Therefore, 2H nuts can replace 2HM nuts, but the reverse is not permissible.These nuts can be manufactured in accordance with ASTM A194/A194M standards, ranging in size from 10 mm (7/16 inch) to 4½ inches.
