Većinom su <a href="/wiki/Standard" title="Standard">standardizirani</a>, premda se iz različitih razloga izvode i izvan standarda. Pored tijela s navojem vijak je obično opremljen glavom različita oblika. Glava vijka najčešće je šesterostrana prizma, ali može biti i četverokutna, poluokrugla, valjkasta s ravnim ili upuštenim križem, šesterokutom (takozvani imbus-vijak) ili zvijezdom, potom lećasta, krilna, narovašena, očna ili stožasta (<a href="/wiki/Utor_na_glavi_vijka" title="Utor na glavi vijka">utor na glavi vijka</a>). </p><p><a href="/wiki/Vij%C4%8Dani_spoj" title="Vijčani spoj">Vijčani spojevi</a> izvode se vijkom i <a href="/w/index.php?title=Matica_(naprava)&action=edit&redlink=1" class="new" title="Matica (naprava) (stranica ne postoji)">maticom</a> (glavi slično prizmatično tijelo s navojem unutar središnjega provrta), ili je vijak uvrnut u provrt s navojem jednog od tijela koje se spaja. Radi boljega nalijeganja ili radi sprječavanja samoodvrtanja, vijčanom se spoju ispod glave vijka ili ispod matice stavljaju obični i elastični <a href="/wiki/Podlo%C5%A1ka" title="Podloška">podlošci</a>. Često se upotrebljavaju i dvije matice zajedno, od kojih druga, bliža kraju (takozvana protumatica), služi kao <a href="/wiki/Osigura%C4%8D_(strojni_dio)" title="Osigurač (strojni dio)">osigurač</a>. <a href="/wiki/Dosjed" title="Dosjed">Dosjedni</a> vijci uz stezanje dijelova osiguravaju i njihov točan položaj. Struk je na dosjednoj površini gladak i <a href="/wiki/Bru%C5%A1enje" title="Brušenje">brušen</a>, a rupe <a href="/wiki/Razvrtanje" title="Razvrtanje">razvrtane</a>. Vijci za podešavanje imaju na kraju struka poseban izdanak, a služe za postavljanje dijelova u određen međusobni položaj. Usadni vijci uvrću se u jedan dio stroja, a nemaju glavu; obično se upotrebljavaju za spojeve kućišta, poklopaca i slično. Temeljni ili kotveni vijci povezuju glavne dijelove s postoljem ili temeljem, a izvedeni su ili kao vijci s glavom ili im je glava stožasto prizmatična, rasječena i povinuta, raskovana ili sploštena ili ima neki drugi, često nepravilan oblik koji osigurava dobro držanje kada se zalije u <a href="/wiki/Beton" title="Beton">beton</a> temelja. Posebna su oblika vijci za drvo, kojima je tijelo blago stožasto i završava kao šiljak. Oni se ubrajaju u samonarezne vijke, jer sami sebi narezuju navojnu rupu, odnosno ne trebaju maticu. Imaju širok navoj većeg uspona i upuštenu ili poluokruglu glavu s utorom. Na sličnom načelu djeluju i vijci za lim te vijci za plastiku, koji često imaju završetak tijela poput nareznoga svrdla. </p><p>Osim vijka kao elementa za spajanje, tako se nazivaju i druga tijela s više ili manje helikoidnim oblikom, na primjer <a href="/wiki/Brodski_vijak" title="Brodski vijak">brodski vijak</a> ili vijčani propeler, vijak za pretvaranje rotacijskoga gibanja u translacijsko (<a href="/w/index.php?title=Vreteno_(strojarstvo)&action=edit&redlink=1" class="new" title="Vreteno (strojarstvo) (stranica ne postoji)">vreteno</a>) ili <a href="/wiki/Arhimedov_vijak" title="Arhimedov vijak">Arhimedov vijak</a>. <sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Izvori">Izvori</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Jednostavni_stroj&veaction=edit&section=7" title="Uredi odjeljak Izvori" class="mw-editsection-visualeditor"><span>uredi</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Jednostavni_stroj&action=edit&section=7" title="Uredi kôd odjeljka Izvori"><span>uredi kod</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r41378145">.mw-parser-output .reflist{font-size:90%;margin-bottom:0.5em;list-style-type:decimal}.mw-parser-output .reflist .references{font-size:100%;margin-bottom:0;list-style-type:inherit}.mw-parser-output .reflist-columns-2{column-width:30em}.mw-parser-output .reflist-columns-3{column-width:25em}.mw-parser-output .reflist-columns{margin-top:0.3em}.mw-parser-output .reflist-columns ol{margin-top:0}.mw-parser-output .reflist-columns li{page-break-inside:avoid;break-inside:avoid-column}.mw-parser-output .reflist-upper-alpha{list-style-type:upper-alpha}.mw-parser-output .reflist-upper-roman{list-style-type:upper-roman}.mw-parser-output .reflist-lower-alpha{list-style-type:lower-alpha}.mw-parser-output .reflist-lower-greek{list-style-type:lower-greek}.mw-parser-output .reflist-lower-roman{list-style-type:lower-roman}</style><div class="reflist"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><a href="#cite_ref-1">↑</a></span> <span class="reference-text"> <b>poluga</b>, <a rel="nofollow" class="external autonumber" href="http://www.enciklopedija.hr/Natuknica.aspx?ID=49280">[1]</a> "Hrvatska enciklopedija", Leksikografski zavod Miroslav Krleža, www.enciklopedija.hr, 2015.</span> </li> <li id="cite_note-2"><span class="mw-cite-backlink"><a href="#cite_ref-2">↑</a></span> <span class="reference-text"> <b>kotač</b>, <a rel="nofollow" class="external autonumber" href="http://www.enciklopedija.hr/Natuknica.aspx?ID=33442">[2]</a> "Hrvatska enciklopedija", Leksikografski zavod Miroslav Krleža, www.enciklopedija.hr, 2015.</span> </li> <li id="cite_note-3"><span class="mw-cite-backlink"><a href="#cite_ref-3">↑</a></span> <span class="reference-text"> <b>kolotur</b>, <a rel="nofollow" class="external autonumber" href="http://www.enciklopedija.hr/Natuknica.aspx?ID=32488">[3]</a> "Hrvatska enciklopedija", Leksikografski zavod Miroslav Krleža, www.enciklopedija.hr, 2015.</span> </li> <li id="cite_note-4"><span class="mw-cite-backlink"><a href="#cite_ref-4">↑</a></span> <span class="reference-text"> <b>kosina</b>, <a rel="nofollow" class="external autonumber" href="http://www.enciklopedija.hr/Natuknica.aspx?ID=33319">[4]</a> "Hrvatska enciklopedija", Leksikografski zavod Miroslav Krleža, www.enciklopedija.hr, 2015.</span> </li> <li id="cite_note-5"><span class="mw-cite-backlink"><a href="#cite_ref-5">↑</a></span> <span class="reference-text"> <b>klin</b>, <a rel="nofollow" class="external autonumber" href="http://www.enciklopedija.hr/Natuknica.aspx?ID=32488">[5]</a> "Hrvatska enciklopedija", Leksikografski zavod Miroslav Krleža, www.enciklopedija.hr, 2015.</span> </li> <li id="cite_note-6"><span class="mw-cite-backlink"><a href="#cite_ref-6">↑</a></span> <span class="reference-text"> <b>vijak</b>, <a rel="nofollow" class="external autonumber" href="http://www.enciklopedija.hr/Natuknica.aspx?ID=64590">[6]</a> "Hrvatska enciklopedija", Leksikografski zavod Miroslav Krleža, www.enciklopedija.hr, 2015.</span> </li> </ol></div></div>    </div><noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1&useformat=desktop" alt="" width="1" height="1" style="border: none;
