Shoulder Bolts
Precision Shoulder Bolts for High-Strength Applications
Shoulder bolts, also known as shoulder screws or stripper bolts, are distinguished by a long, unthreaded, cylindrical shoulder that is larger and wider in diameter than the threaded portion. They are designed to facilitate strong connections, but their shoulder also offers the unique advantage of acting as a journal bearing, pivot point, extended shaft, precision spacer, and other similar functions. The precision-ground shoulder provides a surface that provides precise alignment, load distribution, and thread isolation for delicate mating components.
Shoulder bolts serve several purposes: they act as shafts for rotating elements such as bearings, pulleys, or gears, and as precision alignment pins to maintain the correct position of components. The threaded portion allows for secure fastening, while the shoulder withstands lateral forces. This unique design is crucial for applications that subject fasteners to shear stress. Huyett offers a selection of socket head, flat head, and hex head shoulder bolts to accommodate a variety of installation and performance needs.
- Robust Construction: Shoulder bolts are available in a wide range of materials, including alloy steel, Monel, aluminum, multiple grades of stainless steel, and more. Finishes include black oxide and zinc clear.
- Versatile Functionality: They are ideal for use as pivots, shafts, or stationary guides.

What to Consider When Selecting a Shoulder Bolt
Size and tolerances are always an important factor to consider when selecting shoulder bolts to ensure the alignment is correct.
The surface finish is also key – not only will this affect the bolt’s corrosion resistance, but the texture of the shaft surface may impact the performance of mating components.
Finally, consider the head style and how its drive matches the available tools and how its shape will fit within the application space.
