A variety of fasteners are available for screw piles, such as U-shoes, cap plates, bolt fixtures and pile caps. U-shoes,bolt mounts, and flat steel are well suited for fixing timber to screw piles.When the screw pile is left in the concreting, pile caps should be used overthe piles. It is also possible to weld steel beams onto the screw piles, on topof which e.g. a composite slab or hollow-core slab can be installed.
