Screw Down Lid Plastic Enclosures
Envision's custom screw down lid plastic enclosures utilize heat staked threaded inserts to support the covers used on these enclosure options. Most often the inserts are brass threaded inserts with thread sizes of 4-40, 6-32, or 8-32. Other inserts sizes are available as well. See Removable Lid Plastic Enclosures for a more detailed description of this type of custom option using the NMR process.
