For automated, high-speed assemblies, the Huck Auto-Bulb is the perfect solution.  It’s designed with an easy-to-use lead-in point, which means fast, reliable installation. When pulled it has a  broad, blind side bulb, which makes it a good choice for use within thin materials, and within oversized, misaligned, or slotted holes. We stock Huck Auto-Bulb in 400 stainless steel for corrosion resistance.
 
Unique bulbing system for superior blind side strength
