Below is a list of Specialty Fasteners manufacturers from Portola Valley, California. Specialty fasteners are certain varieties of fasteners that are manufactured for a specific industry, job or material. In comparison to general purpose fasteners, specialty fasteners' applications are limited and specific. For example, fasteners made for use in automotive applications, such as a fastener used to mount a stereo console in a specific vehicle model, would not be appropriate for use in a kitchen cabinet mount.
