Professional Applications & Engineering Value

These high-precision 0000-160 thread size flat head screws address critical engineering challenges in miniature assembly applications where space constraints and corrosion resistance are paramount. The 18-8 stainless steel material with passivated finish provides exceptional protection against oxidation and chemical exposure, making them ideal for electronics, medical devices, and precision instruments. The fine thread configuration with Class 2A fit ensures secure fastening in thin materials while the 82° countersink angle allows for completely flush installation in countersunk holes. The fully threaded design maximizes engagement in limited-depth applications, providing superior holding power where standard fasteners would fail. These slotted flat head screws deliver reliable performance in environments demanding both mechanical integrity and regulatory compliance.
