How to select the right screw for your project

Shoulder screws are fasteners with an unthreaded shoulder between the screw’s head and its thread. They connect components that require rotation or axial movement without being removed. These sturdy fasteners are typically used in engines, pharmaceutical equipment, conveyors, and electronic goods. When selecting shoulder screws for a project, it’s essential to consider a few factors, such as diameter, length, and shoulder type. Additionally, note the thickness of both plates (where the shoulder screws will be placed) as it determines the optimum shoulder screw length.

Shoulder screws (also known as shoulder bolts) are unique fasteners used for many commercial, industrial, and home-based projects. While many types of shoulder screws are available, selecting the right shoulder screw for any project can seem intimidating. Fortunately, following a few basic steps makes finding the perfect shoulder screw much easier! First, narrow down whether you need metric shoulder screws or standard shoulder bolts. Metric shoulder screws can be purchased in different sizes and materials depending on the requirements of your project.

Then determine the thread pitch you need, decide if your shoulder bolt needs to fit into a tapped hole or be non-tapped, and finally, consider the shoulder diameter and length that best suit your application. With these steps in mind, shoulder screw selection is a breeze!
