1. ʻO nā koi Bolt (stud) o ka helu plasticity, ʻoi aku ka kiʻekiʻe o ka pae hana, hiki ke loaʻa i kahi kiʻekiʻe kiʻekiʻe.ʻO nā mea haʻahaʻa haʻahaʻa wale nō ma ka hoʻohaʻahaʻa ʻana i ka mahana wela e hoʻokō i nā koi ikaika, akā ʻaʻole hiki ke hoʻokō i ka plasticity, nā koi paʻakikī.ʻO ka hoʻāʻo ʻana o Fastener, brittle fracture e hoʻokolokolo ʻia ʻaʻole kūpono ʻole (ʻoiai inā ʻo ka ikaika tensile e hoʻokō i nā koi.) Hāʻawi pū nā pahu kila i ka ikaika tensile kiʻekiʻe, ʻo ia ka mea e hōʻoia ai i ka paʻakikī paʻakikī o ka bolt.
2. Nut mechanical properties pili i ka nut hardness a me ka nut kiʻekiʻe, nut wall thickness, no laila, ʻaʻole kiʻekiʻe nā koi waiwai. e pili ana i nā koi o ka paʻakikī i ka hoʻolako ʻana i kahi mea ʻoi aku ka holomua.
