Hollo-Bolt is the only HSS expansion bolt ICC-ES and LARR approved for all Seismic Design Categories (SDC) A through F, in compliance with the International Building Code.

Lindapter’s expansion bolts require installation access from only one side of the structural steel section and offer a faster alternative to welding or through-bolting, saving both time and money.
