## 🔌 Function

Clamps two components together through a plain hole into a tapped one, with a hexagon head for a socket or spanner.

## ⚠️ Common Signs of Failure

-   Joint working loose or weeping at the face
-   Head rounded or the corners chewed
-   Thread picked up, galled or stripped on removal
-   Shank corroded or pitted, particularly where it passes through a wet joint
-   Screw snapped on tightening or found sheared in the hole

## 🛠️ Service Notes

-   Check the length against the screw you removed before fitting — 50 mm is the whole point of this number
-   Clean the tapped hole out before refitting; corrosion in the thread gives a false torque reading
