BIS Certification for High Strength Structural Bolts IS 3757

Often used in structural steel to steel fastening applications, the structural bolt is a hex head style threaded fastener designed to provide the heavy duty holds needed in steel building frameworks. The heavy hex head of the bolt gives this fastener a wider bearing surface to distribute the load better. These bolts are furnished in several sizes to meet diverse application needs. Made with weathering steel and carbon alloy steel etc. these Structural Bolts offer the best possible strength in the structural work. Also, these are perfect in terms of heat treatment, hot-dip, mechanical properties, threading, chemical composition and other factors.

High-strength structural bolts are normally responsible for transferring loading from structural beams to columns in a bolted connection, contributing to stability and integrity of a structural system and withstanding both thermal and mechanically induced loads produced from a catastrophic event such as fire.

BIS is a statutory institution established under the Bureau of Indian Standards Act,1986 to promote harmonious development of the activities of standardization, marking and quality certification of goods and attending to connected matters in the country.
