JT4-FR Stainless Steel 304 (A2) Tek Screws

EJOT JT4-FR fasteners are manufactured from 304 (A2) grade austenitic stainless steel suitable for use when drilling and tapping into ALUMINIUM sections.

The FR range of fasteners are manufactured with low profile dome head which is a rounded top with a flat underside, they sit above work surfaces and tend to be used when requiring a more decorative finish.

FR fixings can be powder coated to colour match main façade for less visibility of the fixing head.

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 S12 stainless steel / 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.

The fixing can fix into aluminium sheets and sections 1.5-6.0mm in thickness.

RJ offer a complete range of EJOT stainless steel fasteners for other external applications.
