ATE 03351701012 Screw

Product Overview

The ATE 03351701012 Screw, also known in various markets as the Verschlussschraube, Hauptbremszylinder or Screw Plug for Brake Master Cylinder, is a precision-engineered component designed to secure the master cylinder in automotive braking systems. This screw functions as a critical sealing element that prevents fluid leakage and ensures reliable brake performance.

Key Functional Characteristics

• Sealing Integrity: The screw’s threaded design creates a tight seal within the master cylinder housing, maintaining hydraulic pressure and preventing brake fluid loss.
• Load Capacity: Engineered to withstand high internal pressures typical of automotive braking systems, ensuring long-term durability under repeated use.
• Corrosion Resistance: Manufactured from high-grade alloy steel treated with protective coatings, the screw resists rust and corrosion even in harsh environmental conditions.
• Compatibility: Fits a wide range of vehicle models including those from VW, Audi, Seat, Vauxhall, Mercedes-Benz, Saab, Opel, and others. The screw’s dimensions are standardized to match the master cylinder assemblies specified by ATE.

Technical Specifications

Installation Guidelines

1. Preparation: Clean the master cylinder threads and surrounding area with a solvent to remove oil, dirt, or old sealant.
2. Thread Engagement: Align the screw’s head with the master cylinder opening. Hand-tighten initially to ensure proper seating without cross-threading.
3. Tightening Sequence: Use a calibrated torque wrench set to the manufacturer’s recommended torque (typically 12–15 Nm). Apply torque in a star pattern if multiple screws are present.
4. Sealing Verification: After installation, perform a pressure test or visual inspection for any fluid leakage around the screw head.

Maintenance and Inspection

• Inspect the screw periodically for signs of wear, corrosion, or loosening. Replace immediately if any defects are observed.
• Avoid over-tightening during reassembly; excessive torque can strip threads or damage the master cylinder housing.
• Store spare screws in a dry environment to preserve their protective finish and prevent oxidation.

Applications Across Vehicle Brands

The ATE 03351701012 Screw is widely used across multiple automotive manufacturers. Its standardized dimensions allow it to be a drop-in replacement for:

• VW, Audi, Seat models featuring the 03.3517-0101.2 master cylinder.
• Vauxhall, Mercedes-Benz, Saab, Opel vehicles that employ the same master cylinder architecture.
• Other brands such as Ford, Toyota, Honda, and various commercial vehicle lines where the screw’s thread profile matches the required specifications.
