Max ft-lbs $P$ : pitch of the thread in milimeters; it has been obtained from DIN 13-28 (ISO Metric Screw Threads; Coarse and Fine Screw Threads from 1 to 250 mm), $\mu_G$ is the coefficient of friction in the thread (in this case we have considered $\mu_G$ and $\mu_K$ equal and obtained from UNE 17-108-81), $\mu_K$ is the coefficient of friction in screw head (in this case we have considered $\mu_G$ and $\mu_K$ equal and obtained from UNE 17-108-81), $d_2$ pitch diameter of the bolt head in mm; it has been obtained from DIN 13-28 (ISO Metric Screw Threads; Coarse and Fine Screw Threads from 1 to 250 mm), $D_{Km}$ Effective diameter for the friction moment at the bolt head or or nut bearing area and it is defined by the following expression, $d_w$ is the outside diameter of the plane head bearing surface of the bolt; generally bearing surface in this case we have considered similar to the distance between flat surfaces of the head (head size), and it has been obtained from the following standards: DIN 7623 ,DIN 7643, DIN 7991, DIN 908, DIN 912, DIN 931, DIN 933, DIN 934, DIN 960, DIN 961, DIN 985, ISO 10642, ISO 4014, ISO 4017, ISO 4032, ISO 4762, ISO 7040, ISO 8676, ISO 8765, MBN 10105, $D_{Ki}$ is the inside diameter of the bearing area,we have considered the same as $d_2$ and it has been obtained from DIN 13-28 (ISO Metric Screw Threads; Coarse and Fine Screw Threads from 1 to 250 mm), $F_{Mzul}$ Permissible assembly preload defined by the following expressions, $\nu$: utilization fator of yield point stress (limit of full plasticization of th cross section at risk)durin tightening. Both wrenches use 3/8 square drive to accept standard 3/8 bits. The calculator is generic an can used for imperial and metric units as long as the use of units are consistent. WebThe torque required to achieve this force with a dry bolt is calculated to 2022 Nm. 209-231 Torque (lb-ft) 7/8 - 14 n/a I need to set it half way between marks to get a point 5.

Unfortunately, this information can be difficult to find, so here are some of the more common torque's you'll want to know. This question was sent in: what is the correct torque for different connectors, and in what documents give this information? 3/16" This resistance can be correlated to, but is not a direct measurement of, fastener tension. If none of the above keeps the post from slipping, either: use a different post because there is a sizing issue, or. Join CR4, The Engineer's Place for News and Discussion! Re: Torque setting to tightening a M8 brass nut? You don't mention the thread pitch so I'll assume it is coarse (M8 x 1.25). The correct tightening torque for this combination with a dry brass nut would be about 110 in-lbs. Brass nuts are commonly used on SST bolts for a couple of reasons. 54 M60x2 1) Enter thread diameter nominal value in section Thread Size. Note: seals on an internal male 30 seat Any tool, even a torque wrench, should be used with common sense. 13-15 See also related article on Basic Thread Concepts. M10x1 54 - 61 The table is also available as a PDF file. This can damage components, such as a crank ridden with a loose mounting bolt. 125-135 The required bolt clamping force for a joint is 20000 lbs. The purpose of this is to prevent galvanic corrosion of the post and to help keep water from getting into the bottom bracket thorugh the seat post interface. This values are automatically loaded based on iso and metric thread size, what at the same time give us the head and the shape needed for calculation. -24 The crank-to-spindle interface receives quite a lot of stress, making larger threads (M8, M12, M14) a better choice. We don't collect information from our users. 32-35 Due to the nature of the design if you torque a brass SMA to the specified torque of 7-10 in-lbs and the male housing is of the thin wall variety you can get a roll over condition.
