Aircraft Specification Fasteners

Continual search for improved performance has generally meant that all race car components have become smaller and more highly stressed. This is particularly true of fasteners, and now, all leading constructors and teams use aircraft specification fasteners because of the quality, load-bearing capacity, close tolerances and the ability to specify the correct length of the bolt, without the need to shorten.

All of these items are manufactured to aircraft standards and have a corrosion resistant finish.
