Die Cast Zinc part and screws
Die Cast Zinc part and screws
(OP)
I am in the final design stages of a die cast zinc part for good volume production, commercial product. I originally specified a cored, drilled and tapped 10-32 hole, 2 places. I was able to increase the height of the screw boss, to about .250 [room for more if needed] and anticipate the call for cost reductions. I am paranoid about self tapping screws and field installers stripping them out. How do you guys feel about this, especially considering the extra depth of the boss? Also, I changed to 10-24 thread. If I do go to a self tapping screw into a die cast hole, what is the ideal hole geometry and the ideal thread?
Thanks
Thanks

We use Plastite Trilobular screws with our plastic products. But even so we have experienced some broken bosses due to improper assembly or manufacturing.

I would advise you to review the products available from REMINC (same people that Heckler mentioned above). They have several products, as well as preferred cored hole dimensions.
