<p>A split nut is formed from two identical screw-threaded half nuts, each of which has chambered ends, pref. at about 60 deg. to the axis of the nut, to engage in a conical counterbore of a washer or workpiece. When the split nut is tightened, it remains securely in place. Each half nut has side faces extending in radial planes with complementary locating pieces symmetrically disposed on either side of the central plane of the half nut taken at right angles to the axis, and the screw-thread has a start at one end only, whereby one of the half nuts is inverted so that the respective complementary locating pieces engage to align axially the half nuts.</p> |
