The child can practice the action of using a screwdriver by removing and re-inserting four star head bolts using the supplied screwdriver. The set consists of a wooden block with four screws which thread into permanently fixed, threaded bolts. The board also has two insets, one for holding the screwdriver and another for holding the bolts once they've been removed. The supplied screwdriver is lightweight, and has a textured handle for a sturdy grip. The screws can also be used with a standard (i.e. slot head) screwdriver (not supplied).
NOTE: do not overtighten the bolts as this may result in the sunken threaded bolts being removed from the block when unscrewing.
