In my experience the Lo height thread doesn't do anything and there are much better thread forms available. They are not standard 60 degrees included angle. More like 35-40 degrees and coarse pitch.

Can I screw into HDPE sheet? | iPoly

HDPE is a "self-healing" polymer which holds screws securely. As the screw passes through the sheet, the polymer heats up and forms itself to the profile of the flutes. Screw retention exponentially increases as the sheet gauge increases. For best results pre-drill a smaller hole prior to fastening screw into it; this will increase the holding power of the fastener as less polymer is displaced.

Length of Engagement: Fasteners should have a minimum of 2.5 times the fastener diameter for length of engagement into the plastic boss.
