Butlerib® II Fasteners
Stronger Fasteners Maintain incredible strength.
The Butler Scrubolt
Because other manufactures don’t factory punch their structural steel, they are generally forced to use self-drilling screws to make critical clip and panel attachments. Self-drilling screws leave behind metal shavings that can cause rust problems. Butler factory punches structurals and uses Butler Scrubolt™ fasteners which have twice the pullout strength of self-drillers.
