Where these fit on site
Installers commonly reach for this size when a job needs more grip than a shorter screw offers — fixing structural timber boards, framing components, or wooden fixtures where the extra length gives better hold in the substrate. The countersunk head means the fixing sits level with the material rather than proud of it, which matters wherever a flush finish is needed or something is fitted over the top afterwards.
Selection notes
Choose this length when the timber or board thickness calls for deeper penetration than a shorter screw would give. For thinner boards or lighter fixings, a shorter screw from the same range may be the better match — check board thickness against screw length before ordering.
