Aluminum alloy breakstem fasteners with a split tail formation providing a very large blind side bearing area against the rear sheet.

The Avdel® Bulbex® breakstem fastener is designed with a split tail formation, providing a much larger blind side bearing area against the rear sheet. This also allows for a wide variation in material thickness. The Bulbex® blind breakstem fastener is ideal for use with plastic and low strength material.
