Overview
The ZF 0636.016.058 HEXAGON SCREW is a critical fastening component engineered for the WG190, WG200, and WG210 series transmissions. This OEM genuine part secures the differential assembly within the housing, ensuring precise alignment and torque retention under heavy load conditions. As a hexagon-headed bolt, it withstands high shear forces and vibration, maintaining the structural integrity of the drivetrain. The SKU 0636.016.058 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged fasteners in commercial vehicle transmissions.
Symptoms of Failure
- Transmission oil leaks around the differential housing: A loose or fatigued hexagon screw can compromise the seal between the differential and housing, leading to fluid seepage. This is a common sign that the 0636.016.058 screw has lost its clamping force.
- Unusual gear whine or clunking during acceleration: When the hexagon screw fails to secure the 5838109012: DIFFERENTIAL properly, gear mesh clearance increases, producing audible noise under load.
- Vibration in the driveline at highway speeds: A failing hexagon screw allows the differential assembly to shift slightly, causing imbalance and vibration that worsens with RPM.
- Premature wear of the 0750117075: TAPER ROLLER BEARING: Inadequate clamping from a degraded screw leads to bearing misalignment, accelerating fatigue and potential failure.

Frequently Asked Questions
Q: Can I reuse the 0636.016.058 hexagon screw after removal?
A: No. ZF recommends replacing this bolt with a new OEM part each time it is removed, as torque-to-yield fasteners lose clamping force after initial installation.
Q: What torque should I apply to this screw?
A: Typical torque for an M16 grade 10.9 bolt in this application is 210-240 Nm, but always consult your specific ZF transmission service manual for exact values.
Q: Does this part fit the WG180 transmission?
A: Yes, the 0636.016.058 is compatible with WG180, WG190, WG200, and WG210 series, provided the differential housing uses M16 threaded holes.
