The manufacture of BigHead fasteners depends on one core requirement - the ability to weld a thin, large-diameter metal head to a stud or collar, at a strength equal to that of the metal of which it's made. This central skill is at the heart of the BigHead product range, and with the company's latest automatic welding machine now in full production, a major increase in production capacity is on-line, helping to produce the company's range of over 1,200 variants.
