Custom Precision Cam Nuts - Mild Steel With Zinc Plating

 

We had 12,000 pieces of these large custom precision cam nuts manufactured in mild steel for our construction component manufacturer.  Overall length measured 91.7MM and max OD at the base was set to 23.88MM.  M8 X 1.25 6g thread was incorporated on both sides and M12 X 1.75 6h thread was tapped in the center of the base.  Both shoulders were tuned to a 13.37-13.48MM diameter.  Material certs and certificate of conformance was provided with the parts.

Custom Knurled Nylon Insert Lock Nuts

 

These custom knurled nylon insert lock nuts were manufactured using SAE J995 class 8 material with zinc clear finish.  3/8-24 internal thread was incorporated with a 45 degree chamfer and a .551-.562 across the flats hex was formed over the nylon insert.  Overall length measured at .519 +/-.03" and the knurled portion measured approximately .34" in length.  This was a tricky part to tool for and to produce - it took us two sample runs to finally get everything dialed in.
