Sourced directly from Wacker Neuson's parts catalog under the designation Screw-m8x65-hex.hd-8.8-c16, it is a metric coarse-pitch fastener with a 65mm shank length, hexagon head drive, and a structural grade 8.8 rating indicating a tensile strength suitable for load-bearing connections within the heater unit.\u003c\/p\u003e\n\n\u003cp\u003eGrade 8.8 M8 fasteners in Wacker Neuson equipment are specified at a tightening torque of 25 Nm (18 ft. lbs.) for hex head screw connections per DIN 931\/DIN 933 standards, assuming untreated, non-lubricated surfaces and a friction coefficient of 0.12. Using the correct torque value during installation prevents both under-tightening, which can allow joint loosening under vibration, and over-tightening, which can stretch or shear the fastener. When replacing this screw, always verify the mating threads in the heater assembly are clean and undamaged before installation.\u003c\/p\u003e\n\n\u003cp\u003eCompatible models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHSH3000\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43399162167344,"sku":"WACKER-5100079956","price":16.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5100079956.jpg?v=1784092875","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-m8x65-hex-head-8-8-screw-5100079956-for-hydronic-heaters","provider":"CCE Industries","version":"1.0","type":"link"}
