3/8 x 2 1/4 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) is selected when engineers need a shoulder screw that can fasten while also guiding or spacing a mating component. For repair or OEM use, the 3/8 x 2 1/4 shoulder helps give the mating component a consistent shoulder surface for rotation, travel, or spacing. The 3/8 x 2 1/4 configuration is relevant for fixture stops, sliding supports, indexing hardware, and production machinery. Repair Technicians may choose the 3/8 x 2 1/4 size because 18-8 stainless steel gives equipment builders a general-purpose stainless option for shoulder locations exposed to moisture or handling. The 3/8 x 2 1/4 part is useful for both new builds and replacement work where shoulder-based location must be maintained. The 3/8 x 2 1/4 precision shoulder is especially useful where pivots, guides, spacers, or locating surfaces must stay consistent through service cycles.
