World-leading Fastener Technology
ARP started applying technology to race fastener design and manufacturing in 1968. We'll discuss five components of fastener technology in detail.
The following material is intended to provide a brief overview of the metallurgical considerations that influence the design and production of the most reliable fasteners in motorsports. It is hoped that a simple understanding of the knowledge and commitment required to produce this reliability will make your future fastener decisions much, much easier.
The materials ARP uses in fastener manufacturing are listed and compared.
There are six types of metallurgical failures that affect fasteners. Each type has unique identifying physical characteristics. The following examples are designed to be used like a spark plug reading chart to help analyze fastener failures.
