Since the construction will be done only by driving the core bar, you can easily check the completion of construction at glance.Because the main body and threaded portion have the same diameter, drilling to concrete is completed with a small diameter.For construction work, civil engineering work, electrical work, machine equipment construction etc.Nominal Designation of Thread:M8Total Length (mm):50Screw Length (mm):20Max Attachment Thickness (mm):5Pilot Hole Diameter (mm):8.5Maximum Tensile Load (kN):6.5Buried Depth (mm):35Packaged in a pack(up to a total length of 80mm)Packaged in a bag(from a total length of 90mm)SteelSurface treatment: Trivalent chromate treatmentThe maximum tensile load is the value at the concrete strength Fc21N/[[MM2]].
