Reviews
TechFast Heavy Duty Timber To Steel Countersunk/Torx Roof Screw 5.5 x 40mm (100 Pack) is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Does what it says Great product, I drilled a 4.5mm pilot hole to make it easier I wasn't convinced that it would drill itself into a girder but got a good hold so 5 star

Rated 5 out of 5 by from Too notch I didn't really believe these would go into steel without a pilot hole but I used them today to screw batton to a 15mm steel beam and they went straight in. I would definitely recommend them.
