Professional Applications & Engineering Value
Engineered for precision fastening in demanding sectors, these 3-48 UNC rounded fillister head screws address critical challenges in machinery, electronics, and automotive assemblies. The 18-8 stainless steel material combined with a passivated finish effectively counters corrosive agents, reducing maintenance frequency in humid or chemical-exposed settings. The high-profile narrow head design allows secure seating in counterbored holes, while the slotted drive facilitates quick adjustments in space-constrained applications. With fully threaded coarse spacing and Class 2A fit, these screws deliver robust clamping force and resist loosening under dynamic loads, making them indispensable for industrial equipment requiring repeatable disassembly and reassembly.
Specification Summary & Compliance
This screw maintains precise Class 2A thread fit per UNC standards with a diameter of 0.099" and 3/8" length. Manufacturing adheres to ASME B18.6.3 specifications for dimensional consistency. The product is verified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming the absence of restricted hazardous substances for safe use in regulated industries.
