Sri Ramanuja manufactures hexagonal bolts and nuts through forging under controlled heating and forging conditions that ensures good grain flow with the least decarburisation. They have a better bearing capacity than machined bolts. They come in plain carbon, alloy steels and stainless steel. Hexagonal bolts and nuts are hexagonal headed, reamer shanks and flange headed and so on. Range: * Diameters from 16 mm to 42 mm * Lengths from 30 mm to 650 mm * Tensile strengths from 60 kg/ mm2 onwards * Finishes like phosphating, blackodising, zinc and cad plating and so on.
