BLDRCSK – Steel countersunk Orlock rivet
This steel countersunk Orlock rivet is one of our highest strength structural rivets. The blind-side upset is bulbed which helps spread the clamp force so that the joint material is not deformed. The bulbed tail of the Orlock also leaves a neat finish with minimal protrusion on the blind side. The dual locking grooves on the mandrel provide excellent resistance to vibration as well as impressive shear strength and weather resistance while the countersunk provides a flat finish in applications requiring minimal protrusion, like seat tracking and door hinges.
