Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid directly translating "C" as "си". It is a loanword/calque: "C-образный зажим" или "струбцина". A general "clamp" is often "зажим", but "c-clamp" is a specific type of "струбцина".
Common Mistakes
- Misspelling as 'C clamp' or 'C-clamp' (standard is 'c-clamp'). Using it as a verb ('I c-clamped it' is non-standard; 'I secured it with a c-clamp' is correct).

FAQ
Frequently Asked Questions
No, they are the same tool. 'G-clamp' is a common alternative name, especially in the UK, based on a different interpretation of the shape.
In very informal workshop talk, it might be used ('C-clamp it right there'), but it is not standard. The correct usage is as a noun ('use a c-clamp').
The main parts are the fixed 'frame' (shaped like a C/G), the movable 'jaw' or 'shoe' attached to a threaded 'screw', and the 'handle' or 'swivel pad' for turning the screw.
Size is determined by the 'throat depth' (distance from the screw to the frame) and the 'jaw opening' capacity. Choose one that can comfortably fit around your workpiece and apply sufficient pressure.
