M6 inoreva dhayamita rezita re d yeshinda (dhayamita huru yeshinda)
14 inoreva kureba kweshinda yechirume L yeshinda
Zvakadai se: hex musoro bhaudhi M10 * 1.25 * 110
1.25 zvinoreva kukwirira kweshinda, uye rwodzi rwakanaka runofanira kuiswa chiratidzo. Kana ikasiiwa, inoratidza shinda yakaoma..

3. Performance level of fasteners
Magiredhi ekuita mabhoti akakamurwa kuita magiredhi anopfuura gumi akadai se3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, nezvimwewo, pakati pawo mabhaudhi egiredhi 8.8 uye pamusoro anogadzirwa nesimbi yakaderera kabhoni alloy kana zvepakati kabhoni simbi uye vave kupisa kurapwa (kudzima, tempering, etc.) moto), inowanzozivikanwa se mabhaudhi ane simba guru, uye mamwe ose anowanzonzi mabhaudhi akajairika. Iyo bolt performance giredhi giredhi ine zvikamu zviviri zvenhamba, izvo zvakateerana zvinomiririra iyo inonzi tensile simba kukosha uye goho reshiyo yesimba reiyo bolt zvinhu. Nhamba isati yasvika desimali inomiririra 1/100 yekupfuura simba kwechigadzirwa, uye nhamba mushure meiyo desimali inomiririra kagumi reshiyo yemuganhu wegoho kumuganhu wesimba rekusimba rechinhu.
Semuenzaniso: performance level 10.9 high-simba mabhaudhi, zvazvinoreva ndezvi:
1. Simba rezita rekusimba rebhaudhi rinosvika 1000MPa;
2. Chiyero chegoho chebhoti zvinhu 0.9;
3. Simba rekutsvaga rezita rebhoti rinosvika 1000 × 0.9 = 900MPa;
Zvinorehwa negiredhi rekuita bhoti chiyero chepasi rose. Mabhoti egiredhi rekuita rimwe chete ane maitiro akafanana zvisinei nemusiyano wezvinhu zvawo uye mabviro. Chete giredhi rekuita rinogona kusarudzwa pakugadzira.
Giredhi rekuita renati rakakamurwa kuita 7 mamakisi, kubva 4 kusvika 12, uye nhamba yacho inotaridza 1/100 yekunyanya kushushikana iyo nati inogona kumira.
Magiredhi ekuita emabhaudhi nenzungu anofanirwa kushandiswa akabatana, segiredhi 8.8 mabhaudhi uye giredhi 8 nzungu.
