(Factory bolts are Class 10.9, which arguably means they stretch more, giving them better vibration-resistance, but that's probably an engineer's splitting hairs, so I wouldn't hesitate to use these stiffer generic screws on my own or any customer's bike.)\u003c\/p\u003e","brand":"McMaster","offers":[{"title":"Default Title","offer_id":47381462122648,"sku":"DIN 912 M8x20","price":0.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/1344\/9624\/files\/2025-10-2810.45.39.jpg?v=1761666584","url":"https:\/\/shop.nashvillemotorcyclerepair.com\/products\/brake-rotor-bolt-screw-din-912-m-8-x-20-10-9-precote-85-copy","provider":"Nashville Motorcycle Repair","version":"1.0","type":"link"}
