Montessori Plastic Head Thumb Screw Board

This practical life activity is designed for children between the age of 3 and 6 to guide them on how to screw and unscrew a plastic head thumb screw. 

Learning to use the fixed key is an exercise that teaches the child the correct way to do some household chores. Additionally, it helps to stimulate a child’s imagination through the activity of assembling, disassembling, and building.

In our previous video lesson, we learned how to tighten and loosen the plastic head thumb screws. In this video, we will learn how to tighten and loosen plastic head screws.

What are plastic head thumb screws?

Plastic head thumb screws are made up of a stainless steel or alloy steel body with a nylon/plastic head that is either fully or partially threaded. ​Plastic thumb screws generally come with different head styles such as hex, round, etc. that have a textured or knurled surface for easy gripping. These screws can be fastened and loosened up by using a hand without any tools.

The set contains a wooden block and six bolts that screw into permanently fixed, threaded receptacles. Additionally, the board has two insets; one to keep the fixed key and one for holding the bolts once they are removed. The plastic head thumb screw is a screw with a flat hex-shaped plastic head to tighten and fasten the screw using the hands. It helps children to learn how to use plastic head screws by removing and re-inserting them into fixed bolts.
