This method of fastening allows each fastener to reach its maximum theoretical elongation to provide maximum clamping force given that material property and strength.  \u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe major problem with this method is that the fasteners are not reusable. The second problem is that under scrutiny of clamp load 2 fasteners side by side are not applying the same appropriate force within reason.  If we cannot rely on even distribution of load, we cannot rely on these fasteners and its showing in the failures we are seeing. The third problem is the availability of replacements, this means a lot of these fasteners are not being replaced during engine rebuilds.\u003c\/p\u003e\n\u003cp\u003eThe OE B58 Crank pulley fasteners may be fine for OE properties, but they are not adequate for increased output.  The Crank pulley is a 4-piece design friction welded together and specifically uses the 4 bolts to hold it all together.  We are seeing the pulleys explode apart and taking out anything in its path. This includes but not limited to the crankshaft, coolant hoses, and the hood. Our fasteners are a must for big power B58 cars.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSpecifically designed to support the load and tensile requirements of increased output.\u003c\/li\u003e\n\u003cli\u003eRequired to reach ASTM conformance certification.  All Material must conform to AMS batch raw materials.\u003c\/li\u003e\n\u003cli\u003eThread engagement and shank is optimized for each given bolt in its specific location. \u003c\/li\u003e\n\u003cli\u003eMeet or exceed a minimum allowable tensile strength of 190kpsi.  \u003c\/li\u003e\n\u003cli\u003eCustom age hardened \u003c\/li\u003e\n\u003cli\u003eCorrosion resistant, there is no coating or plate film to wear or degrade.\u003c\/li\u003e\n\u003cli\u003eReusable indefinitely unless over yielded past acceptable elongation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis kit contains 4 bolts, use red loctite and toque to 67ft\/lb\u003c\/p\u003e","brand":"Visconti Tuning","offers":[{"title":"Default Title","offer_id":45547861049535,"sku":"sku-43458226389212","price":240.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0268\/2486\/8031\/files\/visconti-b58-crank-pulley-fastener-kit.jpg?v=1777014315","url":"https:\/\/yotanation.com\/products\/b58-s58-crank-pulley-fastener-kit","provider":"Yota Nation","version":"1.0","type":"link"}
