The term 'VELCRO COMPONENT' can be broken down into two parts: the HOOK, which is a 4-letter word. The HOOK is one of the components of Velcro, a brand of fabric fastener consisting of two strips of fabric, one with tiny loops and the other with small hooks. When pressed together, the hooks catch in the loops and hold the pieces of fabric together. The HOOK component of Velcro is the strip with the small hooks that attach to the loops.
