Socket screws for dynamic loading and high stress

Unbrako Pty, Ltd, is the only manufacturer of socket screws in Australia, and makes a range of related high-technology products for automotive engines and defence applications. The company’s range of high-quality socket screws are used for their strength and reliability. Unbrako fasteners are designed to cope with dynamic loading and high stress. The products include the socket head-cap screws — the most widely used fastener in the range. The screws are used in many

mechanical arrangements including machine tools, mining, and off-road equipment. The socket flat-head screw is used in tension applications where underflush seating is required. In tension applications where loading is less severe and appearance is important, the socket button-head screw, with its domed head, is preferred. The range also includes the socket shoulder screw which is used principally in tooling applications, while the socket set screw is used in compression applications

to connect collars and pulleys to shafting. Other products manufactured by Unbrako include the socket pressure plug — used to close and seal openings in hydraulic systems, steel collars, dowel pins, and hex wrenches — which are the standard hand-tool for tightening socket screws. The company also makes the “Sel-lok” spring pin which replaces taper and cotter pins, and the “Conelok” nut, an all-metal prevailing-torque self-lock-ing nut.
