3/8 x 5/8 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) is selected for machinery where a precision shoulder provides bearing contact, location, or spacing in a serviceable joint. When installed in the proper assembly, the 3/8 x 5/8 shoulder can combine fastening with a functional shoulder used for position and motion control. Typical uses for the 3/8 x 5/8 shoulder include material-handling mechanisms, spacer locations, and serviceable pivot points. For the 3/8 x 5/8 size, the stainless material supports general-purpose corrosion resistance for fixtures, automation equipment, and OEM machinery exposed to moisture, which can matter to repair technicians. For OEM work, the 3/8 x 5/8 shoulder provides a clear locating surface while the socket head remains accessible. The 3/8 x 5/8 precision shoulder is especially useful where pivots, guides, spacers, or locating surfaces must stay consistent through service cycles.
