1. Is this a genuine AP screw?
No. It is a generic aftermarket replacement, not original, but dimensionally identical to the 26176 bezel screw.
2. How do I choose the head diameter?
Measure your original screw head with a caliper, then select 2.55mm or 3.9mm. Visible front bezel screws typically have the larger head (3.9mm), while inner/auxiliary screws have the smaller head (2.55mm).
3. Does this screw fit other Offshore models?
It fits 44mm Offshore models with the same bezel thickness (e.g., some variants of 26170, 26400). However, lengths may vary by model/year. Compare with your original. Do not use on 42mm Offshores or Jumbo models.
4. Should I use threadlocker?
A low-strength threadlocker (e.g., Loctite 222) is recommended on the threads to prevent loosening. Use sparingly. Professional installation is advised.
5. Will the screw rust?
Made of quality stainless steel, it resists corrosion under normal wear. Avoid prolonged contact with seawater or chemicals. Wipe dry after use.
