Screwing and Tapping perspex® or Acrylic
Standard taps and dies may be used for cutting screw threads in Perspex® but wherever possible, coarse threads are preferred as they are less liable to damage. Lubricants are essential, water or soluble oil being preferred.
 |
In order to tap acrylic you need to drill the correct sized clearance hole, just like you would in metal. Ensure that the hole is drilled squarely. |
 |
This is the correct sized tap inserted into the tap handle. |
 |
Push the tap into the hole and turn it slowly clockwise. Use some water or suluble oil to lubricate the tap. Turn the tap a few times clockwise and then turn it anti-clockwise. Then complete a few more clockwise turns until you have sucessfully threaded the perspex® |
 |
You can now remove the tap and screw in the correct size machine screw. Threads must not be overstressed and it is not advisable to thread Perspex® if frequent dismantling is likely. In such conditions, threaded metal inserts are recommended. |
