Metric DIN 478 Square Head Bolts with Collar manufacturers in India

Metric DIN 478 square head bolts with collar are externally threaded fasteners with a square shaped head with a washer face. The head configuration of the DIN 478 square head bolts provides a greater larger surface area and hence these bolts are used mostly  where larger bearing surfaces are required. DIN 478  square head bolts can be  partially threaded with thread length dependent on the diameter and length of the bolt. Bhalla Fasteners is the leading  manufacturer, supplier and exporter of  Din479 shead bolts with short dog point in USA ,UK ,Poland, Germany , Austrailia, Ireland, and other  European countries.
