bigHead
Discover the Original bigHead® from Bossard—the ultimate, invisible fastening solution designed specifically for lightweight composites and uncompromised aesthetics.
Secure Fastening Without Drilling or Riveting
For over 40 years, bigHead® has revolutionized lightweight manufacturing by combining a perforated head welded directly to versatile fastener fixings. Designed to be surface-bonded or molded seamlessly into composite materials like carbon fiber, bigHead® fasteners deliver the same locking strength and efficiency as traditional hardware without destroying your material or disrupting the sleek design of your application.
