Overview
The ZF 0736.010.033 HEXAGON SCREW is a critical fastening component engineered specifically for the WG150 and WG200 series transmissions. This OEM genuine part secures the transmission housing assembly, ensuring precise clamping force and structural integrity under high-torque operating conditions. Located at key junction points within the gearbox casing, this hexagon screw (SKU: 0736.010.033) prevents relative movement between mated surfaces, maintaining the alignment necessary for optimal gear engagement and hydraulic pressure retention. As a factory-specification fastener, it is designed to withstand vibration, thermal cycling, and load stresses inherent in heavy-duty industrial applications.
Symptoms of Failure
- External oil seepage at housing joints: A loose or fatigued 0736.010.033 hexagon screw can compromise the seal between the TRANSMISSION HOUSING and TRANSMISSION HOUSING, leading to visible oil drips or wet spots around the bolt heads.
- Intermittent gear slipping under load: Insufficient clamping force from a worn hexagon screw may allow micro-movement of internal components, causing erratic power transfer and temporary loss of drive.
- Abnormal vibration or rattle from the transmission case: A degraded fastener can result in loosening of the GROOVED STUD and adjacent hardware, producing audible metallic noise during operation.
- Difficulty maintaining hydraulic pressure: When the hexagon screw fails to secure the housing properly, internal fluid pathways may shift, leading to delayed shifting or clutch slip.

Compatibility
This hexagon screw is a direct-fit OEM component for ZF WG150 and WG200 series transmissions. It is commonly used in the WG180, WG200, and WG150 models, where it secures the main housing sections. The part also interfaces with the TYPE PLATE mounting points and is frequently replaced alongside the HEXAGON SCREW (0636100621) during housing rebuilds. Always verify thread pitch and length against your specific transmission variant before installation.
