The D-Fixings screws are fire-rated screws with a 40mm long shaft and close threads which combine to provide exceptional performance.

These D-Line D-Fixings screws are ideal for securing D-Line fire-rated Safe-D ranges and other electrical installation equipment in popular substrates - including masonry, plasterboard / breeze-block, concrete, brickwork and wood. 

The D-Fixings have been extensively tested, and are certified to hold Safe-D clips and cable loads up to 970°C for 2 hours, after withstanding stress vibrations and water sprays also.

In fire tests the D-Fixing screw threads remain securely embedded with no need for anchors or plastic wall plugs (which typically melt at 160°C).
