Professional Applications & Engineering Value

Engineered for demanding industrial applications, these passivated 18-8 stainless steel oval head screws deliver critical corrosion protection where moisture, chemicals, or outdoor exposure threaten fastener integrity. The combination of 80,000 psi tensile strength and Rockwell B80 hardness ensures reliable performance in vibration-prone assemblies, while the fully threaded UNC coarse spacing provides superior pull-out resistance in softer materials. The Phillips No. 2 drive facilitates efficient installation in high-volume production environments, and the standard oval head profile with 82° countersink creates seamless flush mounting for aesthetic-sensitive applications. These flat head screws solve common engineering challenges by maintaining structural integrity while meeting strict regulatory requirements for industrial components.
