1. Risks of using stripped screws:
Insufficient tightening force: Stripped screws have deformed or missing threads, preventing them from forming a complete thread in the material, resulting in insufficient preload and loose connection.
Exacerbated hole wall damage: When screwed back in, the damaged threads will scrape against the inner wall of the screw hole, expanding the stripped area and increasing the difficulty of repair.
Secondary failures: Under vibration or load conditions, stripped screws are prone to loosening, potentially causing abnormal equipment operation or even safety hazards.
2. Temporary solutions in special circumstances:
If no replacement parts are available on-site and the connection is non-critical, the following emergency measures can be tried:
Apply thread-locking agent (such as Loctite 243) before screwing in the screw to increase friction;
Use spring washers or nylon locking washers to prevent loosening;
Only suitable for low-load, static connections, and replacement should be done as soon as possible.
3. Correct handling method:
Replace with new screws: Prioritize using brand new self-tapping screws of the same specification to ensure connection reliability. Repairing Screw Holes: If the screw hole is stripped, the internal thread can be restored by re-tapping or installing a wire thread insert.
Optimizing Installation Process: Check the pilot hole size and control the tightening speed and torque to prevent stripping again.
✅ Key Recommendation: Self-tapping screws are consumable fasteners. Once stripped, they should be treated as faulty parts, and direct replacement is the safest and most efficient solution.
