Key uses of hex socket head shoulder bolts:

1. Mounting rotary and linear components:
   • Gears, pulleys, sprockets, bearings, and other rotating components
   • Acting as a linear slide to align punches and molds
   • Building custom cam followers
2. Precision applications requiring accurate positioning and alignment:
   • Used extensively in industries like aerospace, automotive, and manufacturing
   • Provide precise positioning and alignment due to the smooth, unthreaded shoulder
3. Stripper applications in injection molding machines:
   • Also referred to as "stripper bolts" when used to attach stripper plates
4. General machine construction and assembly:
   • The unthreaded shoulder allows the bolt to be used as a shaft or dowel for rotating or sliding parts
   • Commonly used in punch-and-die mechanisms or plastic injection mold sets to act as linear slides

Hex socket head shoulder bolts are versatile fasteners that are widely used to mount and align rotating components, provide precise positioning, and act as linear slides or shafts in various industrial and mechanical applications. Their unique design with an unthreaded shoulder makes them well-suited for these purposes.
