DESCRIPTION
www.hales.com.au Unbrako fasteners are the strongest off the shelf threaded fasteners you can buy. When purchasing Unbrako socket screws, you can be sure that they meet or exceed the strength levels of all current standards including ANSI, ISO and DIN to name a few. Why Unbrako? Reliability, high pressure, stresses and speeds in today’s machines and equipment demands stronger more reliable fasteners, as the rising cost of down time is intolerable., 57
