A kamin huwa tip ta 'qfil b'żipp, sa ċertu punt simili għal bolt, tipikament magħmula mill-metall, u kkaratterizzati minn linja spirali, magħrufa bħala  ħajt maskili  (ħajt estern). Viti huma wżati għall-materjali jaqflu mill jħaffru fil u jservi ta 'feles fi materjal meta mdawwar, filwaqt li l-iskanalaturi qatgħat ħajt fil-materjal maqfula li jista jgħinu pull materjali maqfulin flimkien u jipprevjenu pull out. Hemm ħafna viti għal varjetà ta 'materjali; dawk komunement tinqafel viti tinkludix injam, metall folja, u plastik.

A kamin se normalment ikollhom  ras  fuq tarf wieħed li fih forma mwaqqfa speċjalment li tippermetti li jkun imdawwar, jew  misjuqa , b'għodda. Għodod komuni għall-viti sewqan jinkludu tornaviti u wrenches. Ir-ras hija normalment akbar mill-korp tal-vit, li jżomm il-vit milli jiċċirkulaw fil-fond mit-tul tal-vit u biex jipprovdu  wiċċ li jkollu

Injam kamin:

viti injam kmieni kienu magħmula bl-idejn, b'serje ta 'fajls, furmaturi, u għodod oħra qtugħ, u dawn jistgħu jiġu spotted faċilment billi tinnota l-ispazjar irregolari u forma tal-ħjut, kif ukoll bħala trade fajl baqa' fuq ir-ras tal-vit u fiż-żona bejn ħjut. Ħafna minn dawn viti kellhom tmiem mingħajr ponta, neqsin kompletament il-punt għax-xejn qawwija fuq kważi kollha viti injam moderna. Eventwalment, tornijiet kienu użati għall-manifattura viti injam, bil-privattiva kmieni għandha tiġi reġistrata fuq 1760 fl-Ingilterra. Matul il-1850s għodod Tagħwiġ ġew żviluppati biex jipprovdu linja aktar uniformi u konsistenti. Viti magħmula ma dawn l-għodod għandhom widien tond bi ħjut qawwija u mhux maħduma. Xi viti injam saru ma imut qtugħ kmieni kemm-1700s tard (possibilment anki qabel 1678 meta l-kontenut ktieb ewwel ġie ppubblikat fil-partijiet).

Ladarba magni bil-kamin tidwir kienu fl-użu komuni, viti injam aktar disponibbli kummerċjalment ġew prodotti b'dan il-metodu. Dawn viti injam maqtugħ huma kważi invarjabbilment għax-xejn, u anke meta l-parti dritta għax-xejn mhix ovvja, dawn jistgħu jkunu ndikati minħabba li l-ħjut ma jestendux fil-passat id-dijametru tas-sieq tagħha. Tali viti huma l-aħjar installati wara tħaffir toqba pilota bi ftit drill għax-xejn. Il-maġġoranza ta 'viti injam moderna, ħlief għal dawk magħmula mir-ram, huma ffurmati fuq il-magni ħajt rolling. Dawn viti ikollhom dijametru kostanti, ħjut b'dijametru akbar mill-qasba, u huma aktar b'saħħithom minħabba li l-proċess ta 'irrumblar ma jaqtax l-qamħ ta' l-metall.
