• Shoulder Screws reduce rotation through locking
• Stainless Steel 303 is known for its ability to cut and finish with relative ease
• Socket cap head fasteners are very common in industrial applications
• Driven by a flat-bladed driver
• Fine threads tap better into harder materials and thin walls, and are stronger in tension than coarse threads

Shoulder Screws, also known as Shoulder Bolts, are used for several different applications, including those that involve rotation or require a locking type of screw. Shoulder Screws are distinct from other types of screws due to the fact that they are only partially threaded, leaving a smooth-sided round or square shaft between the threading and the head. This shaft is usually slightly larger than the threaded portion of the screw. Often used in automotive and mechanical applications.

Stainless steels are used for their corrosion resistance, high-temperature strength, scaling resistance, and low-temperature toughness. These properties account for their extremely wide use in practically every industry. Austenitic Stainless Steels are alloys of iron and carbon that contain between 16% and 30% Chromium, a maximum of 0.15% carbon, along with Nickel (or Manganese), and other alloying elements. The chromium, which helps develop a passive surface oxide film, provides corrosion resistance in stainless steels. Austenitic Stainless Steels are designated by a 3 digit SAE Stainless Steel Grade beginning with the number 3 (e.g. 304, 316).

Stainless Steel 303 contains 0.15% carbon, along with traces of sulfur and phosphorus which makes this a free machining alloy. Free machining refers to the ability to cut and finish the materials without heavy wear on the machining tools. Tensile Strength is 35000 psi (pounds per square inch).

With a high cylindrical head, socket cap head fasteners have a recessed driving area and offer high hold power at high torque levels. Common applications for slotted screws include woodworking, although the drive style is not designed to be used with power drivers.

A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Fine threads are preferable when working with harder materials or when threading into a thin material. They are also stronger in tension than coarse threads, and generally provide higher shear strengths.
