The Avdelok® lockbolt is a two piece assembly consisting of a bolt and collar. Although they are in the blind fastener family, they are not blind fasteners as access is required from both sides of the workpiece to install the bolts and collars. They provide higher shear strength, tensile strength, clamp load and vibration resistance then most other products in the Avdel® blind fastener family. Material options include aluminum, steel and stainless steel with diameter ranges of 3/16" to 3/8"
