Mphete inagawanika pamalo amodzi ndikupindika mu mawonekedwe a helical. Izi zimapangitsa kuti makina ochapira agwiritse ntchito mphamvu ya masika pakati pa mutu wa fastener ndi gawo lapansi, zomwe zimasunga makina ochapira molimba pa gawo lapansi ndi ulusi wa bawuti molimbana ndi nati kapena ulusi wa gawo lapansi, kupangitsa kukangana kwambiri ndi kukana kuzungulira. Miyezo yovomerezeka ndi ASME B18.21.1, KUCHOKERA 127 B, ndi United States Military Standard NASM 35338 (yomwe kale inali MS 35338 ndi AN-935).

Makina ochapira masika ndi helix ya kumanzere ndipo amalola ulusi kumangika kumanja kokha, mwachitsanzo, kuwongolera kozungulira. Pamene kutembenuka kwa dzanja lamanzere kukugwiritsidwa ntchito, m'mphepete mwake mumaluma pansi pa bawuti kapena nati ndi gawo lomwe latsekeredwa, motero kukana kutembenuka. Chifukwa chake, ochapira masika sagwira ntchito pa ulusi wakumanzere ndi malo olimba. Komanso, sayenera kugwiritsidwa ntchito pamodzi ndi chotsuka chophwanyika pansi pa makina ochapira kasupe, chifukwa izi zimalekanitsa kasupe wa kasupe kuluma mu chigawo chomwe chidzakana kutembenuka.

Ubwino wa makina ochapira masika ali mu mawonekedwe a trapezoidal a washer. Ikakanikizidwa ku katundu pafupi ndi mphamvu yaumboni wa bawuti, imapindika ndikuphwanyidwa. Izi zimachepetsa kuthamanga kwa kasupe kwa mgwirizano wa bolt womwe umalola kuti ukhalebe ndi mphamvu zambiri pansi pa milingo yogwedezeka yofanana. Izi zimalepheretsa kumasuka.

Mapulogalamu

Makina ochapira masika amalepheretsa mtedza ndi ma bolts kuti asatembenuke, kutsetsereka komanso kumasuka chifukwa cha kugwedezeka ndi torque. Ochapira masika osiyanasiyana amachita izi m'njira zosiyanasiyana, koma lingaliro lalikulu ndikusunga mtedza ndi bolt m'malo mwake. Ena ochapira masika amakwaniritsa ntchitoyi poluma zinthu zoyambira (bolt) ndi mtedza ndi malekezero awo.

Makina ochapira masika amagwiritsidwa ntchito nthawi zambiri pamapulogalamu okhudzana ndi kugwedezeka komanso kutsetsereka kwa zomangira. Mafakitale omwe amagwiritsa ntchito makina ochapira masika ndi okhudzana ndi mayendedwe (magalimoto, ndege, zam'madzi). Makina ochapira masika atha kugwiritsidwanso ntchito pazida zapakhomo monga zotengera mpweya ndi zochapira zovala (makina ochapira).
