2. Product Features

Precise OEM dimensional tolerance Manufactured strictly in accordance with MAN original drawing standards. Uniform thread profile, fixed hex head thickness and shank length ensure smooth assembly without grinding or modification, perfect direct replacement for original spare parts.

Grade 10.9 high-strength alloy steel substrate Made of No.45 quenched and tempered alloy steel. After high-temperature quenching and tempering, it boasts excellent tensile and yield strength, far superior to Grade 4.8 and 8.8 ordinary bolts, effectively resisting stretching and fracture.

Fine thread design M10×1.75 Smaller thread pitch provides stronger locking force under the same tightening torque. It stays tight under high temperature and continuous engine vibration, improving cylinder head sealing performance.

Universal standard hex head Fits standard socket torque wrenches widely used in repair shops; no special dedicated tools required for quick disassembly and installation.

Full zinc plating anti-corrosion treatment Complete electro-galvanized coating covers the head, shank and threads without missing plating areas. Effectively isolates water, oil and weak acid/alkali erosion, preventing rust and thread seizure under humid and high-temperature engine compartment conditions.

Stable torque resistance performance Tempering process eliminates internal steel stress. No head deformation, shank elongation or thread stripping when tightened to factory specified torque, able to withstand long-term vibration impact of heavy-duty engines.

3. Product Advantages

Perfect matching for MAN heavy-duty engines Original OEM standard fastener exclusively for cylinder head mounting of MAN D2866 & D2876 engines, widely used on MAN heavy trucks, construction machinery and generator sets. High market demand in Nigeria, Russia and Central Asia aftermarket repair shops.

Outstanding service life & anti-fatigue performance Grade 10.9 high tensile material withstands alternating high temperature stress and persistent vehicle vibration. Service life over 50% longer than Grade 8.8 bolts, reducing failure risks such as loose cylinder heads and engine oil leakage.

Excellent anti-rust & anti-aging capacity Integral zinc plating avoids rust during long-distance sea transportation and warehouse storage, suitable for humid coastal and dusty operation environments.

Low maintenance cost Standard hex design speeds up repair work; fine thread locking structure minimizes repeated re-tightening, cutting labor time for after-sales maintenance.

Convenient bulk export & packing Fixed single and thousand-piece weight for easy customs declaration and container loading. Compatible bulk shipment with other similar MAN fastener part numbers.

High operational safety High tensile strength eliminates bolt breakage during high-load operation, preventing severe engine faults including cylinder head seal failure, coolant leakage and cylinder scoring.
