ASME B18.2.1-15 Hex Head Lag Screws

 ASME B18.2.1-15 is a standard issued by the American Society of Mechanical Engineers (ASME). This standard mainly covers the design, dimensions and specifications of industrial threaded fasteners, especially bolts, screws and studs. Lag screws (also known as lag bolts, tensile bolts, etc.) generally refer to those bolts or screws designed to carry tensile loads. ASME B18.2.1-15 Hex Head Lag Screws typically have higher strength and tighter tolerances to ensure they don't break or fail when subjected to tensile forces.
