Gayka:
1) mashina va mexanizmlarning qismlarini bir-biriga mahkamlashda ishlatiladigan detal; vint yoki boltga burab kiritiladi. Gaykaning ichi rezbali, sirti olti yoki toʻrt qirrali va dumaloq boʻladi. Tojsimon va quloqli gaykalar ham bor. Gaykaning oʻlchamlari, odatda, standartlardan olinadi, lekin balandligi 0,8 d dan kichik boʻlmasligi kerak (d — bolt yoki vintdagi rezbali qismning tashqi diametri). Gayka poʻlat, rangli metall va polimerlardan tayyorlanadi. Avval tokarlik stanoklarida dumaloq yoki qirrali material qirqib olinadi, soʻngra tegishli stanoklarda unga rezba ochiladi;
2) vintli mexanizmlarda vintning aylanma harakatini boshqa detal va uzellarning ilgarilama harakatiga aylantirib beradigan detal. Masalan, domkratda shunday Gayka bor.
