Base plates in various lengths are available to compensate uneven scaffolding foundations. The base plates thread is cold formed and rounded to allow the wing nut to be quickly screwed up or down, while also making cleaning easier. It is important to note the 25% of the base plates length or at least 15 cm should always be in the scaffold standard.
Head jacks are used to support the timber or steel beams on top of scaffolds, also the thread is cold formed which can supply high loading capacity.
