BLDBCSK – Aluminium countersunk Orlock structural rivet
The Aluminium countersunk Orlock is one of our highest strength rivets in aluminium. 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.
