What are Metric Security Socket Countersunk Sealing Screws?
This Self Sealing Screw is configured with a rubber O-ring which, when squeezed during the fastener’s installation, creates a permanent hermetic seal to stop internal and external leakages and prevent contaminants and toxins from seeping into the environment.
A high-tech Countersunk Sealing Screw, produced by US based company ZAGO, the primary purpose of this fastener is to protect machinery from damage by aggressive substances, even under extreme temperatures and atmospheres. These Metric Countersunk Sealing Screws are manufactured to meet Military Standard NASM 82496, with pressure resistance to 1500 psi.
For optimal performance, it’s recommended to install a clearance hole into the mating panel, allowing the O-Ring to reshape itself within this gap. This forms an airtight seal, whilst permitting metal-to-metal contact.
This Sealing Screw is fitted with a Security Socket Drive, compatible with our range of Security Hexagon Drive Bits. This tamper proof driver offers increased resistance to vandalism over a standard Socket Drive.
Accu also supplies a Metric Torx Security Countersunk Sealing Screw, which allows for high torque transmission and increased cam-out resistance.
Security Socket Countersunk Sealing Screws are manufactured from 304 (A2) Stainless Steel as standard.
The captive O Ring can be supplied in a range of materials, with Buna, Fluorosilicone and Viton (Fluorocarbon) options all offered as standard. Other Screw and O Ring materials can be requested if required.
