O le sikulima o se meafaigaluega e faʻaogaina ai le faʻaogaina o le tino ma le matematika faʻavae o vaalele faʻaoga, taamilosaga lapotopoto, ma le feteʻenaʻi e faʻagasolo malie ai mea ma vaega o masini. O le sikulima e vili e le tagata lava ia o se fa'ailoga fa'apipi'i i lona pito. Screws o se mea fou masani a tagata i le talafaasolopito atoa, ma i tulaga o le faʻaaogaina, ua taʻua i latou o se tasi o mea sili ona lelei a tagata.
O fa'ailoga fa'ato'a fa'ato'a fou, fa'aigoa fo'i fa'avili fa'alila. "Screw" o se faaupuga lautele mo faʻamau, faʻaaogaina i tautalaga i aso uma.
O le si'usi'u o le sikulima e vili e le tagata lava ia e pei o se pito vili po'o se pito mata'i. E le manaʻomia se faʻaogaina fesoasoani ma e mafai ona vili saʻo, tapuni, ma faʻapipiʻi i totonu o mea o loʻo faʻapipiʻiina poʻo le faʻavae, e faʻasaoina tele le taimi faufale. Pe a faatusatusa i sikulima masani, o lenei ituaiga o sikulila e maualuga atu le malosi o le toso i fafo ma le taofiofia o le mana, ma mautinoa o le a le tatalaina e tusa lava pe a uma ona faʻaaoga umi. E saogalemu le faʻaaogaina, aua e maeʻa le viliina ma le taina i le taimi e tasi, faʻafaigofie le gaioiga.
Talosaga: O se ituaiga o sikulima e masani ona faʻaaogaina mo le faʻapipiʻiina o laupepa uʻamea i fausaga uʻamea, ma e mafai foi ona faʻaoga mo le faʻapipiʻiina o uʻamea manifinifi i fale faigofie. E le mafai ona fa'aogaina mo le fa'amauina o u'amea-i-u'amea.
Mea: E maua i u'amea ma u'amea u'amea, fa'atasi ai ma u'amea u'amea toe vaevaeina i vasega eseese.
Actuations: Φ4.2 / Φ4.8 / Φ5.5 / Φ6.3mm, e mafai ona faʻatalanoaina umi faʻapitoa i luga ole talosaga.
Ituaiga faufau fau:
Ulu ta'amilomilo (Michelson/Phillips/Torch), Countersunk (ulu mafolafola)/Michelson/Phillips/Torch, Fufulu Hex, Fufulu ulu lapotopoto (ulu mafolafola tele), Ulu pu, ma isi.
