Bulb-Tite is the original load spreading rivet. During installation the body of the rivet folds into 3 separate legs which creates a large bearing
surface and distributes the clamp force allowing soft or thin materials to be joined without damage. The mandrel of the rivet will break flush
with the head over a wide grip range which results in impressive shear strength. BT Rivets are usually supplied with a neoprene washer
under the head for a weather tight seal.
