Some of the specialty fasteners which are enjoying increasing usage are: thread rolling screws, self drilling and tapping screws, locking screws, tamperproof fasteners, and flanged bolts and nuts.

[considering optimum metric fastener system The Fastener Starter has a square recess hole that accepts a conventional square drive handle or extension to accommodate a variety of applications by providing flexibility in handle style and length. Alternatively, without the insert and with a tool bit, the Fastener Starter can torque a fastener. This is achieved by allowing the fastener to slip within the tool insert when used without a conventional tool bit. When used with the insert, the Fastener Starter prevents cross threading and damage to internal threaded holes. The Fastener Starter includes a custom molded insert that can be removed easily and replaced with a conventional tool bit (e.g., a screwdriver or hex-driver bit). The Fastener Starter incorporates a combination of features of several commercially available tools, providing an improved means of installing small fasteners. The Fastener Starter is non-magnetic and does not off-gas, thus meeting flight hardware requirements. It provides better protection against cross threading and loss of fasteners and associated parts. Its design also allows it to be used with or without handles and extenders in other difficult-to-reach locations. Its compact size allows it to be used effectively in cramped, difficult-to-see locations. The Fastener Starter is a more capable and easier tool to use than prior tools. Other commercially available fastener starters are unable to accommodate a variety of parts simultaneously. This is the only currently available tool that can firmly grip and hold a single screw, bolt, nut, washer, spacer, or any combination of these parts. The Fastener Starter is a creative solution to prevent the loss of small fasteners during their installation. The material is divided into two sections which include: (1) data concerning a selected group of fasteners and concept for fasteners such as locking devices, couplings, and connect and release mechanisms and (2) discussions on a number of fastening techniques such as those for mounting panel lamps, clamping flange bolts, stretching fasteners, and transferring fuel from a tanker to another vehicle.Д¬handler, Faith Garton, Harry Valentino, Bill Amett, Mike Technology on fasteners and fastening devices is presented, as part of NASA's TU program to provide technical information on devices, methods, and techniques resulting from aerospace research.
