The #4-40UNC screw has an overall length of 4 inches with a thread diameter of #4 and 60 threads per inch that meets the Unified Thread Standard. Its standard tolerance ensures it's well suited for most woodworking or general assembly applications without having to re-cut the threads upon insertion into material such as woods, metals, and plastics. The screw's 3 flute design facilitates chipping away from material allowing it to reduce its weight while maintaining an attractive appearance making them ideal for furniture makers, carpenters or hobbyists seeking versatile and consistent threaded rods for constructing projects.
