FAQ
Frequently Asked Questions
No, it is a highly specialised technical term used almost exclusively in mechanical engineering, particularly relating to boilers and pressure vessels.
No, 'staybolt' is exclusively a noun. The related action would be 'to stay' in a technical sense, but the noun form does not convert to verb use.
Its primary purpose is to hold two parallel plates (like the walls of a boiler) together, resisting the internal pressure that tries to push them apart.
A staybolt is specifically designed to work in tension (pulled apart), often connecting two specific points in a structure under stress. A regular bolt is often used in shear (sideways force) or simpler clamping.
