Professional Applications & Engineering Value
These 4-40 UNC coarse thread tapping screws are precision-engineered with 410 stainless steel to address common industrial fastening challenges. The thread cutting design (Type F) creates precise mating threads in brass, cast iron, and sheet metal components, eliminating the need for separate tapping operations and reducing production costs. The fully threaded configuration ensures maximum thread engagement and pull-out resistance, while the Phillips drive provides reliable installation with standard tools. This combination makes them ideal for high-volume assembly lines, metal fabrication, and equipment manufacturing where durability, corrosion resistance, and installation efficiency are critical.
Specification Summary & Compliance
These screws feature 4-40 UNC coarse threads with standard Class 2A tolerances, 3/8" length, and pan head style. Manufactured from 410 stainless steel with a blunt tip and right-hand thread direction, they comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across various industrial applications.
