Square Head Bolts from Fabory, Various Types Available Directly from Stock     

As the name suggests, square-head bolts have a square head instead of a hexagon. The 90° corners provide more grip than a hex bolt, which has 60° corners. This way, the square bolt prevents the socket from slipping off the bolt head.  

At Fabory, you can find various types of square-head bolts: 

DIN 478: A square head bolt with a collar. The collar itself is round to increase the contact surface.  

DIN 479: A square head bolt with a short shank.  

DIN 480: A square head collar bolt with a rounded shank.  

We have standard square head bolts in stock from M6 up to M24. We offer the square head bolts in class 8.8 or 10.9 in plain steel. If you have questions about the application or choice of square-head bolts, please do not hesitate to contact our product experts. We are happy to help you choose the suitable fastening materials for your project.
