Select an OSG thread forming tap based on material hardness and thread tolerance. For ductile materials like aluminum or brass, use a standard cobalt tap like this 5/16-24 UNF. For harder steels, choose a tap with higher cobalt content or TiN coating. Always match the tap tolerance (H7) to your required thread class (2B-3B).
