SnapRite® Mandrel—Stainless Steel is the official and only guaranteed mandrel of the SnapRite System. Use this mandrel when installing fasteners using the SnapRite System Dies and a rivet gun.
Each SnapRite Mandrel will set 1 to 4 snap component sets before breaking or bending. Do not reuse a bent mandrel. It is not necessary to break the mandrel when setting parts unless the snaps are stainless steel. Generally two good squeezes will properly set snap components.
