Din 557 square nut manufacturers in India

DIN 557 square nut  is a four-sided nut. Compared to standard hex nuts which has six sides, din 557 square nuts has 4 sides hence their geometry provides a greater surface area to apply higher torque when tightening and also a greater surface are in contact with the part being fastened, thereby increasing the resistance to loosening (though also greater resistance to tightening). They are also much less likely to become rounded-off after repeated loosening/tightening cycles. Din 557 square nuts are typically mated with square-headed bolts.

Din 557 Square nut size basically refers to its nominal thread diameter. Typically, machine screw sizes range from about #2 to 1/2″ and regular from 1/4″ to 1 1/2″ & M6 TO M36.

  • DIN 557 nut is used in the production of agricultural machinery, machinery and machine tools for joining fasteners that are subjected to dynamic influences and vibrations. DIN 557 nut is installed in a pre-prepared groove square shape. Using a square nut simplifies installation by fixing the nut in the groove and making the attachment point more reliable.
