Home / Screws & Bolts / Hexagon Head Screws / Hexagon Bolts (Part Threaded) / UNC Hexagon Bolts Product Description Hexagon Setscrews and Hexagon bolts are essentially the same, apart from one key difference. This being that setscrews have a fully threaded shaft, right up to the head, whereas bolts are only partially threaded and after a certain length, will have a section of plain unthreaded shaft. These are tightened and loosened with a standard spanner matching the head diameter (across the flats) and are made from bright zinc plated 8.8 grade high tensile steel.
