BOLTS

Overview

Flagship Product Photo:BOLTS

These are the most typical examples of fasteners used for assembling engines and fuselage panels.They are manufactured from a variety of materials in order to meet application requirements.Thus,for assemblies requiring high tensile strength and fatigue strength,high-tension (up to 260ksi) bolts are suitable;for applications involving high temperatures and corrosive conditions,nickel alloys and heat/corrosion-resistant steels are chosen;and if weight is critical,titanium alloys are employed.
