No…No…No… You are taking it wrong, Hahaha… Actually this article is not about SEXUAL THREESOME ACTIVITIES involving Three People, This article is about INDUSTRIAL THREESOME ACTIVITIES involving Three Products i.e. Nut + Bolt + Washer.
These three have no separate existence. Generally when we buying ‘Screws’ Nuts would not be expected to be included, But ‘Bolts’ are often sold with same threaded Nut & same matching Washer.

A BOLT is called a MALE Element that connects two objects. To ensure the connection to be permanent and doesn’t dismantle a NUT & a WASHER, These two FEMALE Elements are used.
A BOLT is an externally threaded fastner designed to make a temporary assembly of two or more similar or dissimilar objects, And is normally intended to be tightened or released by torquing a NUT.
Usually Spanners and Powerd Wrenche Machines are used to tighten.
