Replacing it with a genuine OEM component restores the correct mechanical adjustment range and ensures reliable, repeatable pitch control during concrete finishing operations.\u003c\/p\u003e\u003cp\u003eWalk behind trowels subject their hardware to significant vibration, abrasive dust, and repeated mechanical stress across long finishing cycles. An adjusting screw that is corroded, cross-threaded, or out of specification will introduce slop into the pitch adjustment mechanism, making fine surface work difficult or impossible to achieve. Sourcing a direct OEM replacement guarantees correct thread pitch, material hardness, and dimensional tolerances as engineered by Bartell Global.\u003c\/p\u003e\u003cp\u003eCompatible with the following Bartell Global walk behind trowel models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBC436\u003c\/li\u003e\n\u003cli\u003eBC446\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Bartell Global OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Bartell","offers":[{"title":"Default Title","offer_id":43412763770928,"sku":"21811","price":39.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/21811.jpg?v=1784314314","url":"https:\/\/cce-industries.com\/products\/bartell-21811-adjusting-screw-30mm-oem-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
