The concept of using helical threaded fastening dates back many centuries. Nearly as old is the consequential search for a means of keeping these same fasteners secure until removal is required. Although this characteristic is seemingly the most desirable, any weekend mechanic knows the opposite is usually true: it only stays together when you need to take it apart.
Fastener enhancement products are traditionally comprised of the most basic concepts, including cotter pins and deformed components for locking, and messy greases and anti-seize products for lubricating. In recent decades, adhesives and coatings of higher technology have come into play, making strides in the reliability of fastener systems. Today, various new highly specialized product choices and wider application opportunities are available.
