Small Diameter Low Profile Blind Threaded Inserts have reduced profile heads and smaller diameter bodies to provide excellent spin out resistance in smaller holes or close to edge applications. During insertion, the insert's body expands 360º to fill the hole, thus creating exceptional torque strength and vibration resistance. A backside flange is also formed, even in multiple material thicknesses, without any need for adjustments.
