What is High Strength Structural Bolts With Nuts And Washers?

High strength structural bolts are often used in fastening structural steel to steel. These structural nuts and bolts are a hex head style threaded fastener designed to provide the heavy duty holds needed in steel building frameworks.

Seen in heavy construction jobs, structural bolts are used with a nut and hardened washer. The heavy hex head of the bolt gives this fastener a wider bearing surface to distribute the load better.The high quality steel used to create these bolts are designed for strength and durability.

Product Features

▲High strength high tensile bol.

▲Structural high tensile nut (deeper than standard).

▲One through hardened washer (recognised by the nibs) per bolt in each box or pack.

▲Structural bolts come fully assembled with the nut and washer attached.

▲Hot dipped galvanised finish for maximum corrosion protection.

Applications

High strength bolts or structural bolts are made to be used with heavy hex nuts to connect structural members. To be considered a structural connection, it has to conform to specific ASTM standards.

What is the difference between a common bolt and a high strength bolt?

Ordinary bolts are generally made of ordinary steel (Q235) and only need to be tightened. Ordinary bolts are generally 4.4, 4.8, 5.6 and 8.8 class. High-strength bolts are generally 8.8 and 10.9 class, of which 10.9 class are mostly. The screw holes of ordinary bolts are not necessarily larger than high-strength bolts.

The advantage of using bolts of high tensile strength is that bolts made from high tensile steel can withstand high levels of strain without losing their strength or structure.
