What are Metric Phillips Pan Head Sealing Screws?

In contrast to standard Phillips Pan Head Screws, this self sealing variant is fitted with a uniquely engineered groove under the head. This allows for a captive rubber O-Ring to be pre-fitted, creating a tighter seal compared to using a separate O Ring, and benefitting from metal-to-metal contact with the housing material when installed.

Designed to form a 360° seal when fastened, preventing leakage or damage as a result of contaminants, this highly specialised type of fastener is fitted with the common Phillips Drive for simple and effective installation.

The air-tight hermetic seal provided by these Phillips Pan Head Self Seal Screws has been trusted by the military and defense industries for over 25 years, meeting Military Specifications MS3212 / 3213 and NASM82496. Self Seal Screws are designed to maintain optimum performance in machinery, even under extreme pressures and temperature conditions, and are pressure-resistant to 1,500 psi.
