Shoulder Bolts

Shoulder bolts are straight mechanical fasteners with partially threaded shanks that are used in situations where pivoting or movement is necessary, though they may also be used to prevent motion where fully threaded bolts may loosen. Also known as shoulder screws or stripper bolts, these unique devices can be found in a variety of applications as both stationary and rotary fasteners.

The shoulder in shoulder bolts refers to the unthreaded portion of the shank located directly below the head. This portion of the bolt may be either round or square. Aerospace, automotive and mechanical industries use round shoulder bolts both in finished products and in manufacturing equipment where movement is required. Square shoulder bolts are used in this settings as well as applications such as woodworking as they resist rotation, providing a more secure clamp than fully threaded screws which may loosen due to vibrations. Beyond the shape differentiation, there are several different types of shoulder bolts. Locating screws, socket shoulder screws, stripper bolts, swing bolts and latch bolts are just a few examples. These bolts are all most commonly made of steel alloys with varying amounts of carbon, manganese, molybdenum, silicon, sulfur and phosphorous additives. These materials offer high tensile strength, corrosion resistance and specific surface qualities that may be enhanced with a number of treatments and finishes. Zinc plating and black oxide finishes are among the most common options.   

The manufacturing process used to create shoulder bolts is similar to that of other bolt types. A steel wire rod is first heated consistently for an extended period of time and all rust particles are removed. If needed, the metal is coated for added protection. Cold forging is then used to shape the rod at room temperature and the rod is forced through dyes at a high pressure to be shaped into long perfectly round rods. Once cut down to the desired length, a second dye shapes the head of the shoulder bolt which may be square, hexagonal or slotted. Cold forging using high pressure rollers is then used to press in the thread pattern at the end of the shaft while leaving an unthreaded shoulder. The finished course-pitched shoulder bolt is then ready for use in a variety of applications. It is important to note that the length of this particular type of bolt is a measurement of the unthreaded shank or shoulder rather than the full length of the device. Along with length and material considerations, key size, weight, thread size, shoulder diameter, threaded diameter and head type and diameter should all be considered and selected according to the requirements of the intended use.
