This heavy section drill screw is suitable for securing materials to thick or heavyweight metal sections on site. Featuring a self-drilling tip, it is used to fasten components such as roofing sheets, cladding, or metal framing directly, without the need for separate pilot holes.
The 5.5 x 40mm size and five-point thread allow for reliable penetration and grip in dense substrates. A 16mm washer is included to spread load at the fixing point, making it practical for use with purlins, beams, or structural connections where even pressure distribution is required.
