About this product

Overview

High-strength hex head bolts carry structural and machinery loads in steel plants, conveyor galleries, crane girders and fabricated structures. S A Engineering manufactures them in Bhilai with matching hex nuts, in diameters from M12 to M64 and lengths up to 500 mm, with the thread pitch as per IS 1363.

Each lot is made to the diameter, length, thread length and strength grade on your drawing or purchase order, so the bolts suit the joint they are meant for rather than the nearest catalogue size.

  • Machinery and equipment mounting in steel plants, mines and workshops
  • Conveyor, crusher and material-handling frames
