Carriage Bolts
We offer a wide range of metal bolts and studs. What is the difference between screws and bolts?
Bolts can be described as long shafts with a distinct head on one side. These are generally partially threaded. A fully threaded bolt is referred to as a screw.
Square Neck Carriage Bolts
This is known by different names such as Carriage Bolts, Coach bolts/ Round Head Square neck bolt, Mushroom Head Square neck bolt etc. Useful for fastening wood and metal together.
It is distinguished from other bolts by its shallow mushroom head followed by a square neck, while the shank cross section of the bolt is circular.
This gives the bolt its self locking feature. The square neck grips into the part being fixed preventing the head from turning when the nut is tightened.
Standard – DIN 603

Flange Bolts
Flange bolts, also called Hex Flange Screws, are a special type of bolt which have a flange below its head. They look like a bolt with a washer attached to the head.
The flange provides a more even distribution of the load. Flange bolts eliminate the need to use a washer giving higher flexibility in a wide range of operations.
Standard – DIN 6921.
Materials – Mild Steel and Stainless Steel.
