World-leading Fastener Technology

Design

Today’s critical fasteners – head studs and bolts, main studs and bolts, and driveline – have been designed stronger than ever before to handle the extreme loads. As a results, installation pre-loads – the amount the fastener is stretched during installation – are very high. The design of automotive bolts is a complex process, involving a multitude of factors. These include the determination of operating loads and the establishment of geometric configuration. 00053268
