2.The esemokwu n'akuku bụ ihe dị mkpa na-emetụta tightening torque, na ịdị adị nke esemokwu bụ ihe ndabere maka nkịtị ọrụ nke akpọchi nut. Mgbe nut mkpọchi na-arụ ọrụ, enwere nrụgide na esemokwu oche n'elu kọntaktị n'okpuru ike iweghachite ike nke eriri eri. N'oge a na-eji ya eme ihe ugboro ugboro, a na-edobe esemokwu cyclic n'elu kọntaktị, a na-emezikwa ọnọdụ ndị dị nro na nke dị mma na n'ọnụ ya, na-eme ka ọnụọgụ esemokwu dị ntakịrị na mbelata nke kachasị ike nke nut.
3.Due ka n'ichepụta nkà na ụzụ adịghị ike na nkenke ihe mere, e nwere ike ịbụ nkọ nkuku na eri n'ọnụ ma ọ bụ mismatched akụkụ dabara n'etiti akụkụ.

4.Mgbe achọpụtara geometric parameters nke ihe na nut, mgbanwe nke mmechi uru na-enwe mmetụta dị ukwuu na njirimara eji eme ihe nke mkpochi. Ka ọnụ ahịa mmechi buru ibu, ka nrụrụ nke eriri eri ahụ na-abawanye mgbe ọ na-emepe, na-eme ka eriri nke eriri ahụ dị elu, ihe mgbagwoju anya na-esiwanye ike cyclic, na-abawanye FN nrụgide nke ibe eri ahụ, nke nwere omume nke ịba ụba nke screw out torque.
