M20 x 90 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) offers a practical solution when a fastener must also act as a bearing surface, stop, pivot, spacer, or guide. This format is different from standard socket head cap screws because the shoulder is intended to carry the locating or motion-control role. Common uses include Asian-built equipment, die sets, stripper plates, and fixture rebuilds; related sourcing may also include assembly fixtures. Maintenance professionals can use the metric shoulder format when worn guide, pivot, spacer, or stop hardware needs direct replacement. The shoulder can support controlled travel in fixtures, guides, pivots, and stops while the socket head allows accessible installation. The internal hex drive helps keep installation practical in compact assemblies and serviceable equipment layouts.
