Professional Applications & Engineering Value
These 2-56 UNC rounded fillister head slotted screws address critical engineering challenges in precision assemblies where space constraints and corrosion resistance are paramount. The 18-8 stainless steel material, enhanced by a passivated finish, provides excellent protection against oxidation and chemical exposure, extending service life in demanding conditions like electronics enclosures, medical devices, and automotive components. The coarse thread spacing and fully threaded design ensure rapid installation and superior vibration resistance, reducing maintenance downtime. With a high, narrow rounded head profile, these screws offer a low-profile solution that minimizes obstruction while maintaining strong clamping force, making them ideal for applications requiring flush mounting or limited clearance.
Specification Summary & Compliance
This screw meets ASME B18.6.3 specifications for dimensional accuracy and performance, with UNC thread type and Class 2A thread fit ensuring precise tolerance and reliable mating. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety standards for industrial use.
