Bosal 258-987 Stud

Product Overview

The BOSAL 258‑987 Stud is a precision-engineered fastener designed specifically for automotive exhaust systems. It features an M10 thread with a pitch of 1.25 mm, making it compatible with a wide range of vehicles that require robust and reliable fastening solutions in high-temperature environments.

Key Features

• Thread Specification: M10 × 1.25 mm – ideal for heavy-duty applications.
• Material Composition: High-grade alloy steel with a protective coating to resist corrosion and oxidation at elevated temperatures.
• Heat Resistance: Capable of maintaining structural integrity up to 400 °C, ensuring safe operation in exhaust systems.
• Design: Smooth headless profile reduces the risk of burrs or damage during installation.
• Versatility: Suitable for a variety of models including Peugeot 207 (WA, WC), Hyundai, and other vehicles that utilize the BOSAL 258‑987 designation.

Applications

The stud is engineered to secure exhaust manifolds, catalytic converters, and related components. Its robust construction ensures a tight seal against vibrations and thermal expansion, which are common in automotive exhaust systems.

Vehicle Compatibility

• Peugeot 207 (WA, WC) – 1007 (KM)
• Hyundai models that require the BOSAL 258‑987 specification
• Other vehicles with matching M10 × 1.25 mm thread requirements

Installation Guidelines

1. Preparation: Clean the mating surfaces to remove oil, rust, or debris.
2. Thread Engagement: Align the stud with the corresponding hole and rotate clockwise until fully seated.
3. Tightening Torque: Apply a torque of 25–30 Nm (adjust according to manufacturer’s recommendation) using a calibrated torque wrench.
4. Sealing: Use high-temperature thread sealant or PTFE tape if required by the specific application.

Performance Benefits

• Durability: The alloy steel core resists fatigue, ensuring long-term reliability under cyclic loading.
• Corrosion Resistance: Protective coating extends service life even in harsh exhaust environments.
• Thermal Stability: Maintains dimensional stability at high temperatures, preventing loosening or failure.

Maintenance and Care

Regular inspection of the stud is recommended during routine vehicle maintenance. Look for signs of wear, corrosion, or thread damage. If any issues are detected, replace the stud promptly to avoid compromising exhaust system integrity.
