Ultra-Z™ drilling fasteners are manufactured using an innovative tapered compression point process (TCP) with tightened tolerance controls to provide an ultra-sharp cutting edge. The reverse taper design features an extended flute that penetrates thicker materials while guiding chips away from the surface, eliminating clogging and reducing burn-out and waste. Ultra-Z™ fasteners come in a full range of sizes and drives and are available with corrosion inhibiting Oxyseal II™ coating for extended life. |
