Parts Desk Insights

Best Use Case: Use with M8-1.25 threaded hardware to secure a joint and distribute clamping load with a standard hex tightening pattern.

Common Issues: Confirm the thread pitch (1.25) matches your bolt/stud to avoid cross-threading. If reusing fasteners, check that mating surfaces are clean and that any related hardware (washers, lock features) matches the original assembly design.
