OEM WG2229100184 The hollow bolt is a specialized fastener designed to securely connect fluid lines while allowing oil, fuel, or coolant to pass through its center. The genuine SINOTRUK HOWO WG2229100184 Hollow Bolt is an OEM‑grade component engineered for a perfect fit and long‑term durability. As a critical element of the trusted Sinotruk howo parts family, this hollow bolt is crafted from high-strength, anti-corrosion steel to bear heavy loads, resist road impacts, and stand up to harsh weather—effectively supporting key components like brake systems, fuel lines, and turbocharger oil feeds. Its precision‑drilled bore and high‑quality threads ensure leak‑free connections. Investing in this authentic component guarantees reliable fluid transfer, system integrity, and extended service life.
The WG2229100184 is forged from high‑grade alloy steel, providing exceptional tensile strength and resistance to deformation under torque.
The axial bore is drilled and deburred to ensure smooth, uninterrupted fluid flow without restriction.
Zinc‑plated or black oxide finish provides excellent protection against rust and corrosion.
Rolled threads ensure consistent fit and prevent galling during installation.

The hollow bolt may appear simple, but it is a precision component. It must provide a leak‑proof seal while withstanding vibration and high fluid pressures. The WG2229100184 is engineered with a controlled hex head height and bearing surface flatness to ensure even clamping force on the sealing washers. The threads are rolled after heat treatment to maintain strength and accuracy.
The bolt is cold‑headed from alloy steel wire, then heat‑treated to achieve grade 10.9 strength. The axial bore is drilled with high‑precision tooling, and the threads are rolled for improved grain flow.
Every batch undergoes tensile testing, hardness verification, and dimensional inspection. Sample bolts are torque‑to‑failure tested to ensure they meet specifications.
The development of the WG2229100184 Hollow Bolt focused on providing a fastening solution that could withstand the unique demands of heavy‑duty truck systems. Unlike standard bolts, a hollow bolt must maintain its structural integrity while having a hole through its center, which weakens the cross‑section. This bolt is engineered with a larger head and thicker wall section to compensate, ensuring it can still achieve the required clamp load without yielding.
The material choice is critical. Alloy steel grade 10.9 provides the necessary strength while allowing the bolt to be formed and heat‑treated to precise specifications. The zinc plating not only resists corrosion but also provides a consistent friction coefficient during tightening, which is essential for accurate torque application.
Quality control for the WG2229100184 is exhaustive. In addition to dimensional inspection, sample bolts are tested for hardness and tensile strength. They are also subjected to proof load testing to ensure they can withstand the specified clamp force without permanent deformation. Only components that pass all these rigorous checks are approved for shipment.
A damaged or leaking hollow bolt can cause serious issues. In brake systems, a leak can lead to loss of braking pressure. In fuel systems, it can cause fires or engine performance issues. In turbo oil feeds, it can lead to turbocharger failure. Symptoms of a problem include fluid seepage around the bolt head, stains, or low system pressure. If any of these are observed, immediate replacement with a genuine WG2229100184 is essential.
Installation requires care. Always use new sealing washers (copper or aluminum) on both sides of the banjo fitting. Clean the mating surfaces. Insert the bolt through the banjo and hand‑tighten. Torque to the manufacturer’s specification using a calibrated torque wrench. Over‑torquing can crush the washers too much and restrict flow, while under‑torquing can cause leaks.
Field performance of the WG2229100184 bolt has proven its exceptional reliability. In a study of 100 Howo trucks, none showed signs of bolt failure or leakage over 500,000 km. This reliability translates directly to lower maintenance costs and increased uptime for fleet operators.
For parts managers, the WG2229100184 hollow bolt is available individually or in bulk packs, each with a lot traceability label and a QR code linking to installation instructions. Bulk orders (50+ units) receive additional packaging discounts and priority handling.

Our technical support team is available via email to answer any questions regarding installation or compatibility, and we are committed to providing a response within 24 hours.
When ordering, always verify your application’s thread size and length. The WG2229100184 is designed for specific Howo systems; our cross‑reference guide (available on request) helps you select the correct bolt.
In summary, the WG2229100184 Hollow Bolt is a vital component for ensuring the integrity and reliability of your SINOTRUK HOWO truck’s fluid systems. Its precision construction, durable materials, and rigorous testing make it the preferred choice for hollow bolt applications. Trust the genuine WG2229100184 – it keeps your fluids flowing and your systems sealed.
When replacing a hollow bolt, always use new sealing washers. Clean the banjo fitting and bolt threads. Torque to spec using a calibrated wrench. After installation, check for leaks under operating pressure.
