Simple improvement, better hold. The Head Lock attachment system makes head attachment a breeze. It not only holds and grips better than the standard sheet metal screw, it lasts longer and doesn't tear the shaft. Watch for imitations.
Use hexkey to start screw threads. After initial thread is established, continue to tighten till secure. Plastic cap may be hammered or pressed to shear and lock. Make sure that cap completely covers screw.
