Custom Metric Dacromet Coated U-Bolts - M4 X 52.07MM

We had 1,100 pieces of these custom metric dacromet coated u-bolts produced using 42CrMo  material with heat treat hardening.  The part was originally designed to be made using 17-4PH stainless steel material but a number of attempts resulted in multiple failures during bending - the material was too hard and repeatedly snapped as the tool pressed the 90 degree corners.  As a result we switched to the 42CrMo material with heat treat to obtain the required hardness and strength, with a combination of the dacromet coating to achieve the corrosion resistance needed.  Turned out to be a much trickier part than originally anticipated!

Custom Miniature Metric U Bolts - M4 X 0.7M X 15.23MM In A36 Steel Material

These are custom miniature metric u bolts we supplied to our customer at just five pieces for testing purposes before a larger production volume order is placed.  The inside width was maintained at 16MM and the straight portion of each leg was to be set at 15.34MM.  On the metric u bolts with similar inside width, this M4 diameter is typically the smallest we are able to work with.
