Product Group EJOT Super-SAPHIR® fasteners are manufactured from 304 (A2) grade austenitic stainless steel with a hardened carbon steel drill point welded to the stainless steel shank.
Design The hardened drill point enables the screw to drill carbon steel sections and by having the lead threads formed on this hardened point this allows for correct tapping at high drilling speed.
Assembly Where specified they are assembled with a stainless steel / EPDM vulcanised sealing washer ensuring a safe seal every time.
Finish These fasteners are zinc coated for aesthetic reasons and waxed to lubricate the surface during installation.
Colour Matching For colour matching our fasteners can be capped with push-on caps, powder coated or provided with a Colorfast integral nylon head (see Colorfast section).
