Sealing Screws Engineering

We’ve perfected the engineering processes when it comes to manufacturing our sealing screws. Our expertise in analyzing and selecting materials puts us at the top in our field. We’ve tested our sealing screws against aggressive substances and under extreme temperatures and pressures, and we’ve tested them with a plethora of various surface materials. Our engineers use special jigs and tools to design the ideal O-ring for each type of fastener. Our manufacturing processes meet Military standards and our sealing screws are DFARS & ROHS compliant. We use a combination of the following materials for the metal component of the screws: Stainless Steel (most common), Steel, Aluminum, Copper, Brass, Monel, Austenitic,and Titanium. Moreover, our clients customize everything–from threading to head shape to driver type, and even the materials themselves. There are a number of factors one needs to take into consideration when choosing the ideal sealing screw types for an application. Our engineers are always happy to sit down and work with you as you select the best materials for your individual product needs. Please refer to our Screw Material Guide when selecting options to complement your application and please contact ZAGO to receive personal consultation and to learn more about our sealing screws. ZAGO offers the following materials for the O-rings, which come in durometer ranges from 60-70 hardness depending on the chosen material: EPDM, Buna, Neoprene, Silicone, Fluorosiliconme, Viton, and Mil Spec O-ring materials. Other materials are available upon request. When choosing the best O-ring for your project there are several factors to consider: the specific application for which the O-ring is to be used, the size of the fastener to be sealed, the media type that needs to be sealed, and the temperature and pressure to which the O-ring must be subjected. After considering each one of these factors, the appropriate O-ring type is selected. Please refer to our O-Ring Material Guide when selecting the most suitable material for your O-ring and please contact ZAGO to receive personal consultation and to hear more about O-rings.
