## ⚙️ Key Features

-   2.27 g
-   29 applications across the TWD and TAD series
-   Six point socket drive head

## 🔌 Function

Clamps two parts together, driven from a six-point socket recess in the head so it can be tightened in confined space.

## ⚠️ Common Signs of Failure

-   Socket recess rounded out so the tool slips
-   Screw found loose or backed out
-   Thread stripped or the screw snapped at the shank
-   Head corroded so the tool will not engage cleanly
-   Joint leaking or moving because the screw has lost its clamp load

## 🛠️ Service Notes

-   Use the correct six-point key fully seated — a worn or wrong-fit tool is what rounds these out
-   Renew rather than reuse any screw with a damaged recess or stretched thread

## 📦 Condition

-   Genuine Volvo Penta part
-   Brand new
-   Supplied in original or equivalent packaging
