How to say "screw" in Japanese

• ネジJLPT N2approx.Common
  nounThe everyday word for a screw as a physical fastener — the threaded piece of metal you turn with a screwdriver. When English 'screw' means the hardware, this is the default choice.
  この機械きかいは１時間じかんに千せん個このねじを製造せいぞうする。↗

  This machine cranks out a thousand screws an hour.
• ビスCommon
  nounAlso a screw as a fastener, typically a small one; it is the word you meet for the little screws used in machinery and equipment. For general reference to screws, ネジ is the more general word.
• スクリューCommon
  nounThe loanword, heard above all for a ship's propeller — the 'screw' that drives it through the water. As a term for the fastener it is understood, but ネジ is the usual choice.
• ねじるJLPT N2approx.Common
  godan verb, transitive verbA verb: to twist or wrench something, covering English 'screw' only as an action — a twisting, turning motion. It is not a word for the fastener; that sense belongs to the nouns.
  その取っ手とってを右みぎにねじると箱ばこは開ひらきます。↗

  Twist that knob to the right and the box will open.
• 螺旋らせんCommon
  nounPrimarily 'spiral' or 'helix'; as 'screw' it points to the spiral thread or screw shape rather than an individual fastener. Seldom the word you want for an actual screw — that is ネジ.

For the metal fastener use 「ネジ」 (「ビス」 for a small screw); 「スクリュー」 is mainly a propeller; 「ねじる」 is the verb 'to twist'; 螺旋 means the spiral or helix, not a screw.
