Screw Stripping: Potential Issues and Solutions

What potential issue can occur when a hard screw head locks into a soft lip of a screw hole (e.g., Stryker screws)?

A) Screw corrosion
B) Screw head chipping
C) Screw loosening
D) Screw stripping
Final answer:

The potential issue that can occur when a hard screw head locks into a soft lip of a screw hole is screw stripping.

Explanation:

When a hard screw head locks into a soft lip of a screw hole, the potential issue that can occur is screw stripping. Screw stripping refers to the gradual wear and tear of the screw threads, resulting in a loss of grip and the inability to secure the screw tightly in place. This can happen when the soft lip of the screw hole is not able to withstand the torque applied by the hard screw head, causing the threads to become damaged and stripped.

To prevent screw stripping, it is important to ensure that the screws being used are compatible with the material of the screw hole. Using screws made of a softer material or adding a washer to distribute the pressure can help prevent stripping. Regular maintenance and inspections of screws can also help identify any potential issues before they worsen.

Overall, understanding the potential issues such as screw stripping when using hard screw heads with soft screw holes is crucial in maintaining the integrity of structures and equipment.
