Shoulder Screws Shoulder Diameter Length Accuracy and Load Capacity Details

Caliber Enterprise introduces a high-tech capability in fastening when it comes to Shoulder Screws Manufacturer because it provides solutions that are designed in a situation where alignment accuracy, restricted spacing, and hassle-free movement are demanded. These fasteners are very common in tooling, automation equipment and in mechanical assemblies and are characterized by a precision shoulder area between the threaded area and the head. They are made of high grade alloy steel and stainless steel and provide high load bearing capacities, wear resistance and dimensional stability. Nylon Screws may also be incorporated in assemblies where electrical insulation, light weighted construction or chemical resistance are needed to aid non-metallic fastening requirements.


These screws enhance steady positioning as well as minimize the component wear due to a combination of reliability when subjected to continuous motion and shear load, repeated operation cycles. Their constant shoulder sizes contribute to the maintenance of proper spacing and the movement of the parts that are connected can be controlled. In processes that are subjected to extreme temperature or aggressive chemicals or subjected to rigorous mechanical forces, PEEK Screws are often added as a high-performance alternative, since it has outstanding thermal stability and durability. Collectively, these fastening solutions facilitate effective functionality, long durability and reliable performance in the industrial and precision engineered settings.

  • Functional Purpose: Mechanical assemblies Use in mechanical assemblies where precision in the location and smooth rotation are needed.

  • Dimensional Quality: Production of very narrow shoulder diameter and length, which make the spacing of the mechanisms uniform and the movement of the mechanisms consistent in precision driven mechanisms.

  • Material Grades: It is available in grades such as Alloy Steel (hardened), Stainless Steel 303/304 and Carbon Steel depending on the requirements in loads and wear as per the DIN 923 and ISO standards.


  • Other Benefits: The shoulder type has no threads to wear on mating parts, also, the shoulder enhances the service life and the fastener can fulfill the two functions of fastening and directing components in assemblies.

Shoulder screws are required when the smooth, unthreaded shoulder acts as a locating pin, pivot or bearing surface in fixtures, linkages and moving assemblies and require a high degree of accuracy and directional movement. The choice of the diameter of the shoulder, length and grade of the material have a direct influence on the wear resistance and positional accuracy and in compact assemblies such fasteners are frequently tested with Cheese Head Screws to compare the head profiles and load distribution. In a B2B marketplace, advanced specification tables allow buyers to provide a perfect fit of the shoulder dimensions, achieve an accurate estimate of the weight of fasteners, and provide solutions that do not overdesign based on their functional or space constraints.
