With the proper tools, fastener installation is an easy process. Standard drills and the right size socket bit (3/8″ hex, 5/16″ hex, 1/4″ hex) is all thats required. Impact drills are not recommended for drilling fasteners as they often cause paint chipping on the fastener head itself. Although common practise, VerseaFrame does not recommend pre drilling sheets in bundles as hot burs created from the drilling process can embed into the paint finish of your steel panel. These hot burs will rust when in contact with moisture, creating a rusting appearance around the areas that were pre drilled. If pre drilling bundles, it is important to install sheets immediately and wipe away any metal filings or burs that embed on the sheet.
