304 Stainless Steel Bi-Metal Self-Drilling Fasteners JT3 & JF3

EJOT Super-SAPHIR JT3
Stainless-steel 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 and by having the lead threads formed on the hardened point, this allows for correct tapping at high drilling speed. Where specified they are assembled with a stainless steel / EPDM vulcanized 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 EJOT SUPER-SAPHIR innovation can reduce drilling time up to 50% and noticeably saves labor costs when fastening roof and cladding panels. In practice this means a reduction in assembly times.

The EJOT Super-SAPHIR range is used by roofing and cladding manufacturers and installers worldwide, as well as by leading solar mounting system manufacturers.

  • 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 almost 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.

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.

And yes, it works!

EJOFAST's innovative point geometry fastens thin sheet metal fast!

By displacing the material in the axial direction, the screw joint does not produce long metal chips, avoiding extra cleaning work or customer complaints.

The innovative double-thread can reduce installation time considerably and noticeably save 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.
