M12 Stainless Steel Coach Screws 12mm DIN 571

M12 stainless steel coach screws are sometimes called lag bolts or lag screws because they were commonly used to attach lag brackets to wood. They are also used to fasten metal to wood, in applications where a high level of torque is required, such as attaching deck boards to a joist, and sometimes in masonry projects. They feature a self-tapping thread, but it is recommended to drill a pilot hole first for maximum stability.
