Steel Bolts: Shear and Tension Capacity Catalogue

Steel Bolts in Structural Connections

When it comes to constructing robust frameworks, the capacity of steel bolts plays a crucial role. They are essential for connecting various elements in structures, ensuring safety and longevity. What’s the point of a beautiful structure if the connections can’t hold together?

Shear Capacity, Tension Capacity and Detailing

This simple tool can eliminate the guesswork in nominating steel bolts for structural connections. By inputting only the material grade and nominal bolt size, you can quickly determine the necessary load capacities and detailing parameters. Just remember, it’s not all numbers; a bit of humor can make the process enjoyable. Who knew bolts could be so riveting?
