The part number encoded in the official name confirms the key specs: M16 thread diameter, 190mm length, hex flange head drive style, and grade 10.9 high-strength steel construction.\u003c\/p\u003e\u003cp\u003eGrade 10.9 fasteners at M16 size carry a standard coarse-pitch tightening torque of 275 Nm (203 ft.lbs.) per Wacker Neuson torque specifications, with a torque tolerance of -10 percent against steel or aluminum countermaterial. The hex flange head design distributes clamping load across a wider bearing surface than a standard hex head, which is well suited to the structural demands of a trailer tongue connection subject to road loads and vibration during transport.\u003c\/p\u003e\u003cp\u003eReplacing a damaged, corroded, or over-torqued coupler bolt with a genuine grade 10.9 fastener of the correct length is important for maintaining the structural integrity of the trailer hitch interface. Using an incorrect grade or length can compromise clamping force and create a safety risk during towing.\u003c\/p\u003e\u003cp\u003eCompatible models:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eHSH3000\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43399169507376,"sku":"WACKER-5100080738","price":40.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5100080738.jpg?v=1784093092","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-m16x190-hex-flange-head-screw-10-9-5100080738-for-hydronic-heaters","provider":"CCE Industries","version":"1.0","type":"link"}
