Discover more about the Metric Torx Pan Head Sealing Screws range.
This range of self sealing screws features a Pan shaped head fitted with a captive O-Ring, designed to form a 360° seal when fastened. A highly specialised type of fastener, this type of Sealing Screw features the popular Torx Drive (6 Lobe), which provides increased resistance to cam-out during installation.
Unlike a standard Torx Pan Head Screw, this self sealing variant is uniquely engineered with a groove under the head. This means that the pre-fitted rubber O-Ring allows for a tighter seal and metal-to-metal contact with the housing material when installed, compared to using a separate O-Ring.
The air-tight hermetic seal provided by these screws is designed to maintain optimum performance in machinery, preventing leakage of fluids, gases and contaminants, even under extreme pressures and temperature conditions.
Manufactured in the USA by ZAGO to meet Military Spec, sealing screws are supplied by Accu in a range of head and drive types, with 3 O-Ring material options (Buna, Fluorosilicone and Viton) available as standard. Alternative materials are available on request.
