Abstract
a sleeve for anchoring screws etc. into holes in masonry, comprising a tubular plastics mould having at least two d deep slots parallel to the axis from one end, has an external surface profile involving (a) ribs with radial faces, pref. staggered in a cylindrical pattern, to prevent axial with drawal, and (b) ribs with faces parallel to the axis, to inhibit rotation. Opt. the latter ribs are located near the head of the sleeve, i.e. the external end. Pref. the superficial rib crest pattern on the split sleeve body resembles meshed helical ribs of opposing hands (directions of twist). Esp. for inhibiting movement, after insertion, of sleeves made of moulded polyamide resin.
