{"product_id":"collector-bolts-blk","title":"Proform 66757 Collector Bolts-Blk","description":"PROFORM Wedge-Locking Exhaust Collector Bolts ELIMINATE the need to constantly re-tighten collector bolts, and without the need for clips, pins, racing-wire, chemicals or gunk. The secret is in the Wedge-Locking Washer's super-hardened external teeth that \"bite\" into the bottom of the bolt head and the top flange surface. Vibrations that normally cause other bolts to loosen, are blocked by the wedge-locking action that uses tension, instead of friction to stay snug. In fact, contact with oil actually facilitates the effect. Installs\/uninstalls with a normal wrench, lubricate, and then reuse. Each set comes with six Grade 8 bolts (3\/8\"-16 thread, 1\" long) with a black oxide finish, six nuts and six pairs of Wedge-Locking Washers.","brand":"Proform","offers":[{"title":"Default Title","offer_id":51087870820667,"sku":"BCHW_66757","price":54.91,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/5958\/2011\/files\/891d4942e4c71.jpg?v=1775079075","url":"https:\/\/performancepartscanada.ca\/products\/collector-bolts-blk","provider":"Performance Parts Canada","version":"1.0","type":"link"}
