Kukhala ndi mphamvu = mphamvu x dera
Bolt ili ndi ulusi wowononga, gawo la gawo la M24 bolt si 24 m'mimba mwake mozungulira, koma 353 masikweya mamilimita, lotchedwa lothandiza.
Kulimba kwamphamvu kwa mabawuti wamba a kalasi C (4.6 ndi 4.8) ndi 170N/ sq. mm
Ndiye mphamvu yobereka ndi: 170×353 = 60010N.
Malinga ndi kupsinjika kwa kugwirizana: kugawidwa m'mabowo wamba ndi ma hinged.Pamawonekedwe a mutu: khalani ndi mutu wa hexagon, mutu wozungulira, mutu wapakati, mutu wozama ndi zina zotero.Mutu wa hexagon ndi womwe umagwiritsidwa ntchito kwambiri.Mutu wa countersunk umagwiritsidwa ntchito pamene kugwirizana kumafunika
Dzina lachingerezi lokwera bolt ndi u-bolt, magawo osakhazikika, mawonekedwe ake amapangidwa ndi u-wobowoka, amadziwikanso kuti bolt woboola pakati, malekezero onse a ulusi amatha kuphatikizidwa ndi mtedza, womwe umagwiritsidwa ntchito kwambiri kukonza chubu monga. chitoliro cha madzi kapena mbale ngati kasupe wa galimoto, chifukwa cha njira yokonza zinthu monga anthu okwera pamahatchi, omwe amatchedwa bolt kukwera.Malingana ndi kutalika kwa ulusi kukhala ulusi wathunthu ndi ulusi wosakhala wathunthu magulu awiri.
Malingana ndi ulusi wa mano amagawidwa m'magulu awiri a mano okhwima ndi mano abwino, mano okhwima muzitsulo samawonetsa.Ma bolts amagawidwa mu 3.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9 ndi 12.9 malinga ndi momwe amachitira.Ma bolts omwe ali pamwamba pa giredi 8.8 (kuphatikiza giredi 8.8) amapangidwa ndi chitsulo chochepa cha carbon alloy kapena sing'anga carbon steel ndipo adalandira chithandizo cha kutentha (kuzimitsa ndi kutentha).Nthawi zambiri amatchedwa mabawuti amphamvu kwambiri ndipo pansi pa giredi 8.8 (kupatula giredi 8.8) nthawi zambiri amatchedwa mabawuti wamba.
Maboti wamba amatha kugawidwa m'makalasi A, B ndi C malinga ndi kulondola kwapangidwe.Magiredi A ndi B ndi mabawuti oyeretsedwa ndipo ma C ndi ma bawuti olimba.Kwa ma bawuti olumikizana ndi zitsulo, pokhapokha atadziwika mwapadera, ma bawuti wamba amtundu wa C
