Ejot Fasteners for Roofing and Cladding
Ejot Fasteners for Roofing and Cladding

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.

  • Super-SAPHIR JT3 and EJOFAST JF3 are bi-metal self-drilling and self tapping fasteners for both aluminum and steel applications
  • JT4 stainless steel SAPHIR self-drilling and self-tapping screws are for aluminum applications
  • 304 stainless steel self-tapping fasteners are used in a range of pre-drilled materials

EJOT Super-SAPHIR JT3 Bi-metal self-drilling fasteners

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.

EJOT EJOFAST JF3 Bi-metal self-drilling fasteners

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.

  • Excellent clamping characteristics
  • Self-drilling screw without the common drill tip
  • Twin thread for faster installation
  • Asymmetric thread for high-pull-out values
  • New screw point geometry prevents the fastener from slipping
  • Point geometry ensures virtually no metal chips
  • Material SS 304 (A2) with case-hardened drill point
  • Preassembled 304 SS washer with vulcanized elastomer for excellent atmospheric/UV resistance and optimal load transmission and secure sealing.

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.
