Īnother tool for a stuck nut on a bolt, but not a screw, is a nut splitter. Extractors typically work by fitting into a pre-drilled hole in the screw head, allowing the screw remover to grab hold of the screw from the inside and twist. These flutes or grooves grip the rounded nut from the outside, rather than being driven into the hollowed out screw shaft and taking hold of it internally as a screw extractor would. This size is often non-standard for most drill sets, requiring a dedicated drill bit to be supplied with the kit.Ī tool analogous to a screw extractor, but for removing a seized or rounded off nut from a bolt, is a nut extractor, which has tapered, spiral flutes like a screw extractor, but located internally in the tool, not externally. These work well, but have the drawback of requiring the pilot hole to be drilled to a precise size. A further form is a parallel fluted extractor, with no taper at all and thus no wedging. Straight fluted extractors have less wedging effect than tapered screw extractors, so have less tendency to lock the screws into place.
