Origins and Purpose
- The primary goal was to address a significant issue with Phillips heads: cam-out.
- Cam-out occurs when the drive recess slips out due to excessive torque, leading to frustration during fastening.
Key Improvements
- The Pozidriv® drive style retains the self-centering design of the Phillips drive but enhances it in two crucial ways.
- Increased Torque Without Cam-Out: Pozidriv® screws can handle significantly more torque on the fastener recess than Phillips drives.
- Greater Surface Contact Engagement: The design ensures better grip and minimizes slipping when installed correctly.
Identifying Pozidriv® Screws
- Look for four notches marked into the head of a Pozidriv® screw.
- These notches distinguish it from the Phillips head, which lacks this feature.
