Invisible solution

For several years carbon diffusers on Aston Martins have been attached with bigHead fasteners and BigBond adhesive. Surface mounted on the inside of the diffuser, the bigHeads are invisible, with neither rivets nor drill holes necessary. Due to the design of the perforated 'head', glue flows through the holes and hooks the fastener into position, achieving high stability and strength.

The weld integrity of every bigHead fastener is tested in-house. Last year the company achieved the low defect rate of 18ppm and, with the introduction of lean manufacturing, this is expected to fall further.
