Coach Bolts Technical Info

Below is a useful reference table for technical data regarding coach bolts and carriage bolts to DIN 603 specifications. All of our coach bolts and carriage bolts are made to DIN 603 specifications. We offer coach bolts in a number of material and grades, such as bright zinc plated mild steel, 8.8 high tensile steel and A2 stainless steel. We can also source a limited range of A4 marine grade coach bolts upon request. The threaded section on coach bolts ('b' on below image) is not specified by DIN 603, and any product images we use are solely for illustration purposes only, so we ask you to call us to check our current stocks if you have any specific needs for thread length.

The blue highlighted rows in the below table are the 'standard' sizes that our coach bolts are manufactured to, and the measurements of the bolts will not exceed this. As you can see there is a minimum value for each measurement which is within the DIN 603 specification, so any measurement could be within this size range.
