The so-called rolling of threads can increase the strength of the tooth flanks by around 30%. All Pro-Series products are supplied with a nickel coating or optional with a burnished protecting against corrosion in the long term, even under the toughest conditions. Pro-Series stud bolts have a hexagon socket drive on the head side for screwing in the stud bolts. Due to a cone on the engine block side of the bolt, these are not supported on the thread flanks when the nuts are tightened, but in the bore of the thread in the engine block. This support protects the threads when racing engines are frequently rebuilt.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003ePro-Series advantage over other manufacturers is the nuts and washers included in the set, these also have a tensile strength of 1850 N \/ mm².\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eApplication list:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eM2 F87 MY 2015-2021 370PS 410PS 450PS\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eM3 F80 MY 2014-2018 431PS 450PS 460PS\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eM4 F82\/F83 MY 2014-2020 431PS 450PS 460PS 500PS\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Wagner","offers":[{"title":"Default Title","offer_id":48609838268609,"sku":"P102081410.VN","price":749.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0005\/7773\/2663\/files\/e5c50ec4cdec7675ce4eee0d922d8aae.png?v=1727941235","url":"https:\/\/www.urotuning.com\/products\/wagner-tuning-bmw-s55-engine-oem-head-stud-set-burnished","provider":"UroTuning","version":"1.0","type":"link"}
