Professional Applications & Engineering Value

These 6-32 x 2" passivated 18-8 stainless steel truss head screws are engineered to address common industrial challenges, such as corrosion in humid or chemical-exposed settings and the need for reliable fastening under dynamic loads. The passivated surface treatment significantly enhances durability by forming a protective oxide layer, while the wide truss head distributes clamping force over a larger area, preventing sheet metal distortion and improving joint integrity. With a fully threaded UNC coarse design and Class 2A thread fit, these screws provide excellent grip in materials like aluminum and plastics, reducing the risk of loosening in vibrating machinery, automotive assemblies, and electrical enclosures. The combination of 70,000 psi tensile strength and Phillips No. 2 drive ensures quick, secure installations in high-volume production environments, making them a trusted choice for OEMs and maintenance teams seeking longevity and compliance.
