Hex Head Setscrews DIN 933 (ISO 4017) in A4-80 Stainless Steel
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.
