Professional Applications & Engineering Value
These rounded head Phillips screws with internal-tooth lock washers deliver critical vibration resistance in demanding applications where loosening can compromise system integrity. The 18-8 stainless steel construction with passivated finish provides excellent corrosion resistance for electronics enclosures, machinery panels, and outdoor equipment. The pan head design offers a low-profile installation while the coarse UNC threading ensures quick assembly in plastic, aluminum, and sheet metal components. With 70,000 psi tensile strength and full threading, these fasteners maintain clamp force in high-vibration environments like automotive assemblies, industrial controls, and precision instrumentation, reducing maintenance frequency and improving operational reliability.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with UNC coarse threading (2-56 size). Complies with ASME B18.13 specifications for dimensional accuracy and performance. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features include 3/8" length, fully threaded design, and matching passivated finish on both screw and 410 stainless steel washer components.
