Knurling is a widespread manufacturing technique for improving grip or torque force on a huge array of hand-installed components and fasteners. They are especially cost-effective if you simply need the screw to be effective, lightweight, sturdy, corrosion-resistant, non-conductive, and easy to tighten or loosen.
