vijak:

Jebanje je vrsta zatvarač, na neki način sličan vijak, tipično od metala, a odlikuje se spiralni greben, poznat kao  muški navoj  (vanjski navoj). Vijci se koriste za vezivanje materijala kopanjem u i zaglavljivanju u materijal, kada se okrenuo, dok je smanjenje nit kanala u pričvršćenog materijala koji mogu pomoći izvlačenje pričvršćena materijala zajedno i spriječiti izvlačenje. Postoji mnogo vijaka za različite materijale; oni obično pričvršćena vijcima uključuju drvo, lim i plastika.

A vijak će obično imaju  glavu  na jednom kraju koji sadrži posebno formirana oblik a koji omogućava da se uključi, ili  prešao , s alatom. Zajedničke alate za vožnju vijaka uključuju odvijači i ključeve. Glava je obično veća od tijela vijka, koji drži vijak bude prešao dublje od dužine vijka i da pruži  površinu ležaj

Vijak za drvo:

vijke rano drva su izrađene ručno, s nizom datoteke, dleta, i drugih alata za rezanje, a to se može lako uočio ukazujući na nepravilan razmak i oblik teme, kao i oznake datoteke preostale na glavi vijka i na prostoru između teme. Mnogi od tih vijaka imao tupim krajem, potpuno nedostaje oštar sužava tačku na gotovo svim modernim vijke za drvo. Na kraju, tokarilice su korišteni za proizvodnju vijaka za drvo, sa najranijim patent koji se snima u 1760 u Engleskoj. Tokom 1850-ih su razvijeni savijanje alate da pruži više jedinstven i konzistentan nit. Vijci se sa ovim alatima imaju zaobljene doline sa oštrim i grubim teme. Neki vijci za drvo su napravljene sa vrhunskom umire već krajem 1700. godine (možda čak i prije 1678, kada je sadržaj knjiga je prvi put objavljena u dijelovima).

Jednom vijak okreće mašine su u upotrebi, većina komercijalno dostupnih vijaka za drvo su proizvedeni ovom metodom. Ove cut vijci za drvo su gotovo uvijek sužava, pa čak i kada je konusni prihvat nije očigledno, mogu se uočiti jer niti ne produži pored promjer drške. Takvi vijci najbolje instalirati nakon bušenja pilot rupu sa ojačanim burgije. Većina modernih vijci za drvo, osim onih od mesinga, formiraju na mašinama nit valjanje. Ove vijka imaju promjer konstanta, niti sa većeg promjera od drške i jači jer procesa valjanja ne smanji zrna metala.
