Bolts with rolled threads are indeed stronger than those with cut threads due to the cold working process that enhances their tensile strength. Coarse threaded bolts are not specifically used for superior holding force; instead, the choice between coarse and fine threads depends on the application's specific needs, such as the material being fastened and the required resistance to vibration.
