Overview
The ZF 0736.010.201 HEXAGON SCREW is a critical fastening component engineered specifically for the WG250 transmission series. This OEM genuine part secures the TRANSMISSION HOUSING and HOUSING assemblies, ensuring precise clamping force to maintain gear alignment and oil seal integrity. As a hexagon-headed bolt, it provides reliable torque retention under high-vibration conditions typical in industrial drivetrains. The SKU 0736.010.201 is a direct replacement for original equipment, eliminating fitment guesswork and reducing downtime.
Symptoms of Failure
- Oil seepage around housing joints: When the 0736.010.201 hexagon screw loses clamping tension, transmission fluid can escape past gaskets, leaving visible drips under the vehicle or equipment.
- Abnormal gear engagement noise: A loose or fatigued screw allows micro-movement between the COVER and housing, producing a distinct clattering or whining sound during shifts.
- Intermittent gear slipping under load: Insufficient bolt preload can cause the CONNECTING PART to shift slightly, leading to momentary power loss or delayed engagement.
- Vibration at the bell housing: A broken or stripped hexagon screw creates uneven stress distribution, resulting in noticeable chassis vibration during acceleration.

Compatibility
This hexagon screw is primarily designed for the WG250 transmission series. Based on its thread pattern and load rating, it also fits the WG180, WG200, and WG210 models where identical housing bolt patterns are used. Always verify the bolt hole depth and thread pitch against your specific transmission variant before installation.
