Corrosion-Resistant Fasteners

June 23, 2014
Corrosion-Resistant Fasteners
HuckGuard is a zinc-rich basecoat with an organic topcoat that pretreats fasteners from corrosion. The coating lets the company’s HuckBolts and collars sustain up to 1,000 hr of salt-spray testing — with no painting — while those only coated with zinc handle only 100 hr. While HuckBolts have always had a zinc coating, the fastener collars have always been the weak point because of the swaging process. Swaging creates sheer force on the collar, and can erode corrosion-resistant properties.
