How to Say "Bolt" in Japanese

ボルト

boruto[bo̞ɾɯ̟to̞]

The Japanese word for 'bolt' is ボルト (boruto).

ボルト is used to refer to a metal fastener.

Meaning: metal fastener (noun)

How do you pronounce it?

boruto

The word ボルト is also used to refer to the world-record sprinter Usain Bolt in Japanese media, written with the same characters as the metal fastener.
In certain mechanical contexts, if you are referring to the 'nut' that accompanies the bolt, you will use the word ナット (natto). Be careful, as this sounds identical to the fermented soybean dish 'nattō'.
In Japanese electrical engineering, the word ボルト can also mean 'volt', the unit of electromotive force. While written the same way, the context of the sentence determines whether you are talking about hardware or electricity.
