  How to determine the maximum effective clamping length for the flat head tapping screw? The effective length of the  flat head self tapping screws  is the length of the threaded fit. For  flat head self tapping screws  that have an end cone length specified, the maximum effective design clamping length can be determined by subtracting the length of the largest tapered portion from the minimum screw length. For self-tapping screws of type AB, A, and BP, the end length is not included in the size, and the maximum effective clamping length must be calculated by appropriately reflecting the maximum end length coefficient. Note that for combination screws, the increase in gasket thickness must be considered when determining the maximum effective clamping length. The formula for calculating the maximum effective clamping length: Y=L-Z Y: maximum effective clamping length (minimum distance from the head to the end of the first buckle complete thread) L: minimum screw...

Stainless steel self-tapping screws are generally made of 304HC, and some are made of 201, 316 stainless steel. Generally, the hardness required for cutting can be obtained after head and tooth decay. For carbon steel  tapping screw pan head , the relationship between carburized depth, surface hardness, and core hardness is critical. If the carburized layer is too thin, the screwing effect of the screw is poor; if it is too thick, it will adversely affect its torsional strength and the toughness of the screw.
