What are Metric Phillips Countersunk Sealing Screws?
Metric Phillips Countersunk Sealing Screws are engineered with a groove on the underside of the screw head. Combined with the captive rubber O-Ring, this fastener forms a permanent hermetic seal which prevents internal and external leakages.
Produced in the USA to Military Specifications, this type of Self Sealing Screw is also commonly referred to as an O Ring Screw. Phillips Countersunk Sealing Screws are designed to sit flush with the surface of the mating component and help to fortify and protect machinery from harmful contaminants, even operating within extreme temperature conditions and pressures.
These fasteners are manufactured and pressure tested to 1500 psi to ensure suitability across a wide range of industrial applications, including Marine, Defence and Electronics.
This Sealing Screw can be installed using Accu’s range of Phillips Drive Bits or with the correct size Phillips Screwdriver.
For applications requiring increased resistance to cam-out, our range of Metric Torx Countersunk Sealing Screws is also available.
This range of Phillips Countersunk Sealing Screws are made from 304 Stainless Steel, otherwise known as A2 Stainless Steel.
Captive O Ring material options can be chosen from Buna, Fluorosilicone and Viton (Fluorocarbon) as standard. For alternative Screw and O Ring materials, please speak to a member of the Accu team.
This Self Seal Screw range is also available with AccuLock, our specialist thread locking patch, which helps prevent fasteners from self loosening.
