{"product_id":"locking-header-bolts-1","title":"Proform Self-Locking Wedge Header Bolts 66753","description":"\u003cp class=\"part-detail-description\"\u003eProform self-locking wedge header bolts get a grip on your headers that won't let go—until you're ready! These permanently assembled bolt sets feature special washers with super-hardened serrated teeth that, when torqued to 28 lbs.-ft., bite into and grab the bottom of the bolt head and the top surface of the header. Any bolt-loosening rotation is blocked by the wedge-locking action created by the washers' interfacing cams; but what's really impressive is that engine vibration—the enemy—increases the tension, making them even more secure! The bolts are re-useable and you can count on them to not fail. Proform self-locking wedge header bolts put an end to the constant tightening for a leak-free, headache-free future. They're available in different finishes and sizes for applications from 1965 and up.\u003c\/p\u003e","brand":"NPW HILLSBORO","offers":[{"title":"Default Title","offer_id":47447429251304,"sku":"PRF 66753","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0475\/3847\/1064\/files\/pro-66753_sn_xl.jpg?v=1771362379","url":"https:\/\/generalstorespokane.com\/products\/locking-header-bolts-1","provider":"The General Store Spokane","version":"1.0","type":"link"}
