# 994039 Hex Socket Screw | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta hexagon socket screw weighing 0.007 kg and listed for 5 applications across the HPCU, TB and EM series. It is one of only three parts in this number range that reach the HPCU and TB families, alongside washer 994224 and six point socket screw 994278 - so if you are working on one of those units, look at all three together.

Clamps two parts together, driven by a hexagon key in the socket in its head.

## ⚠️ Common Signs of Failure
