Why Replace It?

Over time, original screws may loosen, corrode, or become difficult to adjust underwater. This replacement set restores full function and security to your light handle. For better grip and corrosion resistance, some divers opt to upgrade to a thumb screw or apply thread treatment.

Recommended Use:

• Replace a worn or missing knob/screw

• Keep one as a spare in your save-a-dive kit

• Use with anti-seize or PTFE tape for extended life
