Allen Key Screw Set

The set contains a wooden block and four screws which thread into permanently fixed, threaded receptacles. The board also has two insets; one for holding the Allen key and one for holding the screws once they've been removed.

This set lets students practice the action of using an Allen key (i.e. hexagonal wrench) by removing and re-inserting four hex-head screws using the supplied key.

Board dimension: 22 cm x 10 cm (about 8.5" x 4")

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