JT4-6 Stainless Steel 304 (A2) Tek Screws
EJOT JT4-6 fasteners are manufactured from 304 (A2) grade austenitic stainless steel suitable for use when drilling and tapping into ALUMINIUM sections.
The drill point and thread forms are designed to provide maximum mechanical performance with ease of installation into aluminium or timber substrates.
Where specified they are assembled with a A15 Aluminium / EPDM vulcanised sealing washer ensuring a safe seal every time.
These fasteners are zinc coated for aesthetic reasons and waxed to lubricate the surface during installation.
Subject to design approval we typically recommend using the JT4-6-5.5x22 A15 when fixing profiles and rails into EVT helping hand brackets without a thermal pad and the JT4-6-5.5x30 A15 for brackets with the thermal pad.
Fixing also for use when fixing horizontal rails to vertical rails and for fixing soffit substructures.
The fixing can fix into aluminium sheets and sections 2.0-6.0mm in thickness.
RJ offer a complete range of EJOT stainless steel fasteners for other external applications.
