Oversized Socket Cap Head Screws

ZAGO Oversized Socket Cap Head Sealing Screws are engineered with precision, featuring a custom fit 360° rubber O-ring seal designed to excel in high-pressure environments. The Socket Cap Head provides a deeper and more secure hexagonal socket drive, allowing for higher torque application and reducing the likelihood of cam-out during installation. These sealing screws are particularly well-suited for:

  • Ensuring superior torque transfer and stability in high-stress environments
  • Adapting to irregular surface plates while maintaining a flush, low-profile appearance
  • Providing reliable sealing in large-diameter applications with a more concentrated metal-to-metal contact surface
  • Minimizing the risk of O-ring extrusion or damage through clearance gaps due to its secure design

ZAGO Oversized Socket Cap Head Sealing Screws integrate a 360° rubber O-ring beneath the head, which, upon tightening, expands to form an airtight and watertight seal. This seal is critical in preventing contaminants like water, oil, gas, saltwater, dust, and moisture from penetrating or escaping, thereby protecting sensitive equipment and the surrounding environment.

Crafted from corrosion-resistant materials such as stainless steel, titanium, aluminum, and brass, and available with a variety of rubber O-rings including Silicone, FluoroSilicone, Viton, and EPDM, these screws are designed to withstand extreme pressures, vibrations, and temperature variations. The socket cap head design, with its cylindrical shape and deep socket, offers greater durability and strength, making it ideal for applications requiring higher torque and precision, such as in air tool generators, pumps, compressors, machine parts, electronic devices, and automotive components.

Fully compliant with DFARS, REACH, RoHS, DEKRA, DFARS, NEMA-Ready and Made in USA/Buy American Act regulations, ZAGO Oversized Socket Cap Head Sealing Screws are the go-to choice for applications that demand both high performance and reliability.
