The new EJOFAST JF3 fastener utilises advanced fastening technology for fixing thin metal to thin metal and comes with European Technical Approval 10/0200. The self-drilling bi-metallic fastener is manufactured in high grade A2 austenitic stainless steel with a unique carbon pierce-point tip. Its 5.5mm diameter utilises a buttress thread design, created to deliver high pullout strengths.

The installer immediately ‘feels’ that EJOFAST goes exactly where it should go – no skating on the surface. Installation ‘feels’ equally smooth. Multiple time tests at a drive speed of 1650 rpm with an end loading of 20kg clearly showed EJOFAST to be on average 30% faster than our industry-standard JT3 stitcher. That equates to significant man-hours on any moderate to large installation.

By displacing, as opposed to cutting the metal, the innovative thread creates no debris. Displaced metal is forced forward - creating a tighter joint. On site, the removal of swarf should be ‘good housekeeping’ practice. When‘overlooked’ the swarf is hardly noticeable when a roof is freshly installed, but an eyesore when the swarf has turned to rust. No chippings means no swarf. No swarf means no rust!

EJOT Applitec’s extremely thorough machine-based procedures assessed the new fastener's drilling, tightening, stripping and pullout performance. Finally, Tensometer testing showed that the EJOFAST JF3 offered an improved pullout resistance advantage of 30% over the conventional JT3 stitcher.
