High-Strength Aluminum Inserts, designed for miniaturized space and electronic systems, may be used in most any material, including aluminum and magnesium.  A significant reduction in weight can be realized with these non-magnetic inserts.  They may be installed in materials as thin as 1/8" (1/16" if end may protrude).
