These precision-engineered shoulder screws combine the strength of a hex socket cap screw with the functionality of a shoulder bolt. Manufactured from premium 304 stainless steel, they offer superior corrosion resistance and durability across diverse applications. The hex socket head design enables secure installation using an Allen key, while the carefully machined shoulder provides precise axial positioning - perfect for bearing installations and rotary applications. Available in a comprehensive range of metric sizes from M2 to M12, these versatile fasteners meet various assembly needs. The shoulder design maintains consistent spacing and allows smooth rotation of bearings, bushings, and other rotating components. Their robust construction ensures reliable performance in mechanical assemblies, machinery, and equipment where precise fit and rotation are critical. Each screw features clean threads and smooth finish for optimal fit and function. Ideal for both industrial applications and precision mechanical projects where quality and accuracy are essential.
