Camshaft Retainer Bolt

Camshaft retainer bolt are crucial fasteners in the timing system of automotive and motorcycle engines. These bolts are designed to securely connect the camshaft to the crankshaft gear and timing sprocket, directly ensuring accurate valve timing for optimal engine power output. This camshaft fixing bolt is suitable for gasoline and diesel engines in passenger cars, commercial trucks, and high-performance motorcycles (including Japanese, German, and American models). It is designed to improve long-term engine reliability, minimize loosening under high-speed operation, and provide durable and reliable fastening for the powertrain system.

Each camshaft retainer bolt is manufactured strictly according to ISO 898-1, SAE J429, and GB/T 3098.1 standards, using high-quality materials such as 42CrMo alloy steel and 35CrMo high-strength structural steel. Through advanced quenching, tempering, and surface treatments (including phosphating or blackening), these bolts achieve hardness grades of 8.8, 10.9, and 12.9. They possess superior tensile strength, yield strength, and fatigue resistance, maintaining reliable clamping force in high-temperature environments (-40°C to 150°C) and under intense vibration. Compared to standard carbon steel bolts, our camshaft fixing bolts offer superior corrosion resistance and wear resistance, resulting in extended service life and reliable performance.

Our camshaft fixing bolt series covers a wide range of specifications to meet diverse engine requirements. Thread sizes range from M6 to M16, and lengths from 15mm to 80mm, with each bolt manufactured to 6g thread precision. Optional styles include internal hexagon socket or external hexagon head, and customizable surface treatments such as galvanizing (zinc-nickel alloy, hot-dip galvanizing), copper plating, or Dacromet coating are available. These bolts utilize precision thread rolling technology, resulting in complete and well-formed threads that allow for precise positioning and even torque distribution during assembly, making them ideal for automated production lines. All batches undergo rigorous dimensional and torque testing to ensure the quality and reliability of bulk supply. Bulk supply, quality certified, strict quality control.
