WebISO 16047:2005 specifies the conditions for carrying out torque/clamp force tests on threaded fasteners and related parts. It is applicable, basically, to bolts, screws, studs and nuts made of carbon steel and alloy steel, whose mechanical properties are specified in ISO 898-1, ISO 898-2 or ISO 898-6, having ISO metric threads with thread sizes M3 to M39. WebJul 23, 2024 · Looking at the chart above, the thread column refers to the diameter of the bolt in millimeters (mm). An M3 thread bolt is 3 mm in diameter, and similarly an M5 thread bolt is 5 mm. The larger the bolt, the more torque is needed to achieve the necessary clamping force. For the sake of this article, we’ll use an M12 thread to describe bolt size.
