• Efficient assembly and removal with the 5/64" hex drive, providing superior torque transfer and reducing the risk of tool slippage.
• Maximum grip and holding power from the fully threaded, coarse (UNC) design, ensuring strong engagement in a variety of materials.
• Guaranteed dimensional consistency and interchangeability, manufactured to meet the stringent ASME B18.3 standard.
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives.

Professional Applications & Engineering Value

Engineered for demanding applications, these 6-32 UNC Flat Head Screws provide a robust solution where corrosion resistance and mechanical strength are critical. The 316 Stainless Steel material, enhanced by a passivated finish, offers exceptional protection against chlorides and acidic environments, making these hex drive screws ideal for marine, chemical processing, and food-grade equipment. The coarse thread and Class 3A fit ensure rapid installation and a secure hold in brittle materials or pre-tapped holes, reducing assembly time and preventing thread stripping. The flat head with an 82° countersink delivers a smooth, flush surface, essential for aerodynamic surfaces and machinery where protrusions are not permissible. This combination of features makes it a top choice for OEMs and MRO professionals seeking reliability in industrial fasteners.
