AISI S904 – Test Standard for Determining the Tensile and Shear Strengths of Steel Screws


This standard establishes procedures for conducting tests to determine the tensile and shear strength of steel screws. The screws may be carbon, stainless or bi-metal threadforming or thread-cutting screws, with or without a self-drilling point, and with or without washers. The intended application for these screws is to connect cold-formed sheet steel material.
