Self Tapping Flange Head Pozi Screws 4.2mm 16mm Pack 100

This 4.2mm diameter, 16mm length black self-tapping screw combines increased diameter strength with versatile medium-length penetration. Perfect for general construction and maintenance work, this size is particularly well-suited for HVAC installations, electrical enclosures, and securing metal framework where robust fastening is required through materials of moderate thickness. The flanged Pozi head incorporates an integrated washer effect that spreads fastening pressure across a wider area, protecting work surfaces from damage whilst ensuring secure retention. Self-tapping technology allows the screw to create its own thread as you drive it, saving time by eliminating pre-drilling steps.
