Skink is entirely made of such plastic.
The joins are tongue and grooved, then tapped m5 and scewed together with countersunk allen screws.
A bit over the top perhaps but it has lasted five years!
Problem with wood type screws is they don't always find the same thread when you take them out and put them back, so you end up with little or no grip and your bot coming to pieces in the arena!

has anyone ever pressed a brass insert into the hdpe which is threaded and allows an m5 etc bolt to be screwed in? rather than taping the hdpe itself
i used these on my bot

well i think there holding it together well it dropped off the work bench and it only scratched the plastic but the structure is 20mm hdpe and rg1000Originally Posted by billy breach
I didn't use them in the end- now I have decided just to screw the bolts into the grow with a powerful drill to in effect tap a hole in the hdpe. If you look towards the end of my pneumatics thread (aroun page 8 I think) madox showed a good solution
Page7 its on and a very good idea
