## Description

These center hole adaptors come in packs of four, are .08” thick, and have an outer diameter .54”. Their ½” diameter lip allows them to fit snuggly into the large holes on Actobotics™ channels that change them from ½” diameter holes to .14” diameter holes perfect for the 6-32 socket head machine screws.  Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be intuitively connected together. The wide range of components makes building complex electromechanical prototypes or finished projects a reality. Dimensions: OD - .54” ID - .14" Width - .08”

**Product Type:** physical
