Since the 1920s Ejot has been a leader in fasteners for the construction industry.
Featured here are four series of fasteners for metal roofing and cladding applications.
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. The hardened drill point enables the screw to drill carbon steel sections. Lead threads formed on the hardened point allow for correct tapping at high drilling speed. Where specified, they are assembled with a stainless steel / EPDM vulcanized sealing washer, ensuring a safe seal. These fasteners are zinc-coated for aesthetic reasons, and waxed to lubricate the surface during installation.
The EJOT Super-SAPHIR innovation can reduce drilling time up to 50%, dramatically shortening installation-time while saving labor costs.
The EJOT Super-SAPHIR range is used by roofing and cladding manufacturers and installers worldwide, as well as by leading solar mounting system manufacturers.
Features and characteristics
Fastens sheet metal fast: used extensively for side-lap stitching on exposed fastener metal panel roofs.
For fixing metal profiles, profiled metal sheets, insulated metal panels, solar mounting systems, wind deflectors; directly to steel roof profiles.
EJOFAST goes exactly where it should go – no skating on the surface. Installation also ‘feels’ equally smooth. Multiple time tests at a drive speed of 1650 rpm with an end loading of 44lbs clearly showed EJOFAST to be on average 30% faster than a standard stitcher. This means significant labor saved on any moderate to large installation.
By displacing, as opposed to cutting the metal, this innovative thread creates no debris and swarf. Displaced metal is forced forward - creating a tighter joint. On site, the removal of swarf should be ‘good housekeeping’ practice. ‘Overlooked’ swarf soon turns to unsightly rust.
Tensometer testing shows that the EJOFAST JF3 offers an improved pullout resistance advantage of 30% over conventional stitchers.
The EJOFAST® thin sheet metal screw is part of the latest screw generation at EJOT. It is a self-drilling screw without the usual cutting bit.
The innovative double-thread reduces installation time considerably and noticeably saves labor costs.
The EJOFAST range of bi-metal self-drilling screws are manufactured from SS grade 304 and feature an extremely hard carbon steel drill point in combination with high-performance leading threads.
Specifically engineered to fix components to thin metal profile, EJOFAST features excellent clamping properties.
A/F5/16‘‘ hexagon drive
A range of fasteners manufactured entirely from austenitic stainless steel material grade 304 (A2) suitable for use when drilling and tapping into aluminum sections.
The drill points and thread forms are designed to provide maximum mechanical performance with ease of installation into aluminum or timber substrates.
Where specified they are assembled with a high quality metal and EPDM vulcanized sealing washer ensuring a safe seal every time.
For aesthetic reasons and to provide lubrication during driving a zinc finish plus wax is applied to these fasteners.
A range of fasteners specifically designed for use in roofing and cladding.
The thread forms are designed to provide maximum mechanical performance with ease of installation.
Where specified, they are assembled with a high quality metal and EPDM vulcanized sealing washer ensuring a safe seal every time.
The specified fasteners have a zinc or organic finish for maximum corrosion resistance in their given application.
EJOFAST Superfast Stitching Fastener
EJOT UK on launching the revolutionary new stitching fastener, EJOFAST. Stitchers are used for the end lap fixings of thin metal roofing panels in the building and construction industry. This new stitcher is up to 30% faster and stronger than its industry standard equivalent.
EJOFAST - the new screw generation by EJOT for side lap stitching
EJOT Super Saphir reduces installation time by up to 50% compared to conventional self-drilling screw
