💡 How do threaded metal sleeves prevent stripped holes in soft materials? These captive inserts transfer bolt pressure away from fragile wood or thin sheet metal. You build stronger joints by letting the hardened steel core take the mechanical stress. Grab the right pitch before driving them into your project boards. The serrated outer edges lock tight against steel brackets and wooden cabinetry. - Cut the toothed claws straight into timber and aluminum plates - Swap out worn sections without drilling completely new holes - Keep fixtures rigid when running high speed motors or compressors
