Abstract

Improvements introduced in the object of the main patent No. 401,922 on the process for the manufacture of self-locking screw fasteners of the patch type, characterized in that they include the operations of cooling the fastener element and the polymer patch material that has a crystallization rate that is slower than that of polyethylene from a temperature around the melting point of the polymer material or higher to a temperature below the glass transition temperature of the polymer, and use a cooling rate that is sufficient to reduce crystallization of the polymer to a crystallization shrinkage of about 25% or less of the maximum volumetric crystallization shrinkage of the polymer.
