We offer These U Bolts in compliance with DIN, ISO, JIS or ANSI Standard.
U Bolts have uses as varied as the sectors they support, led chiefly by the aerospace, railway, construction and automotive fields, along with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
U bolts are typically unsuitable for high-temperature environments because the material can degrade and lose clamping force when exposed to elevated temperatures.
