Hexagonal Head Screw Set

( 0 Reviews )

This set lets students practice the action of using a wrench by removing and re-inserting four hex-head bolts using the supplied tool. The set consists of a wooden block measuring 22 cm x 10 cm (about 8.5" x 4") with four bolts which screw into permanently fixed, threaded receptacles. The board also has two insets; one for the wrench and one for holding the bolts once they've been removed. The wrench is made of a chrome-plated alloy and features both open and closed sockets for engaging the bolts.

NOTE: do not overtighten the screws as this may result in the threaded receptacles being removed from the block when unscrewing.
