HARDY Flow Drill Screw System
Product Category: Tightening technology
HDFDS is a?single-sided, pre-hole-free fastening method. Through?high-speed rotation?and axial pressure, the screw penetrates the sheet material, softening it via frictional heat. The screw threads then form a?tight, fit joining with material. This process is ideal for joining?thick aluminum sheets?or applications in?space-restricted areas.
