Machine Bolts

Product Detail
  • Product Code :
  • Machine Bolts
In the pole line industry, crossarm or machine bolts are employed. They usually come with a square nut and have square heads and a semi-cone point. In order to protect the steel, they are usually hot-dip galvanised. We can make crossarm bolts with a diameter of up to 1-1/2′′. The thread length guidelines for crossarm bolts are the same as for pole line fasteners.
