Superglue and nail polish as threadlocker alternatives are two of the most common, often quoted as effective replacements for dedicated threadlockers. Using these two products can indeed lock a fastener in place in the short term. WebThe screw thread is a ridge in the form of a helix on a cylindrical core. The ridge may be triangular (V-shape) or square or round. If the screw thread is triangular, greater friction may be used. If the screw thread is square, larger loads may be lifted. The distance between the adjacent threads of a screw or bolt is called pitch.
