An example of tensile strength is indicated by the prefix "12": X100 N/mm2 and a multiplier is indicated by the suffix "9." Given that both 12.9 and 10.9 have the very same multiplier, the comparison is straightforward: 12 to 10 for both.
Web10 de set. de 2015 · I found a sheared FS93C SS bolt that was holding a mild steel blade onto the bronze rudder shaft of a 30′ sailboat. I have found in the past that 18-8 bolts are more prone to thread galling and stripping than carbon steel bolts or 316SS, and wonder if that might indicate a lower shear strength, tho’ these may have been cheap imported … Web9 de jun. de 2024 · When it comes to nuts and bolts, there are many markings that you may come across.
