Shoulder Screw 3/8 x 5/8 for Impact Sprayers
The 9805352 Shoulder Screw is a precision fastener with a 3/8‑inch diameter shoulder and 5/8‑inch shoulder length. It is designed to serve as a pivot point or mounting fastener in Impact 1640, 1140, 740, 840, and I/IA model sprayers. The unthreaded shoulder provides a smooth bearing surface, allowing attached components to rotate or align without binding.
Over time, shoulder screws can become worn, bent, or stripped, leading to play in pivot points, misalignment, or loosening of critical assemblies. A damaged shoulder screw compromises the precision movement of linkage arms, pump mounts, or control mechanisms. Replacing it with this genuine OEM part restores original fit, eliminates slop, and ensures reliable operation.
