Hex Bolt Full Thread M20 x 20mm in Bright Zinc Plate 8.8 - DIN 933

Commonly referred to as a setscrew or simply as a bolt. The fully threaded DIN 933 or ISO 4017 should not be confused with its DIN 931 equivalent. A standard spanner or ratchet is typically used to fit this product. Used for decades on all types of assembly throughout the world. As with the DIN 931 hex bolt, the hex drive allows a higher torque to be applied. All parts are to DIN 933 except where shown otherwise. The alternative standard ISO 4017 specifies differences in head dimensions for M10, M12 and M14 thread diameters from DIN 933. Please note that due to manufacturing limitations, all nylon variants of these items are only "similar to" and not "in absolute accordance with" the standard specified.
