This comprehensive parts list covers the Hex bolt, Isha pe Hexagonal nut, Flat washer, Spring washer, Cross crew (cross screw), Front lampinstallation plate, connecting plate, and LHex bolt – all engineered to keep your headlights firmly in place. When you choose genuine howo Parts, you ensure perfect fitment, optimal beam alignment, and long-lasting durability for your truck’s lighting system.

Hex bolt

The Hex bolt is a high-strength fastener with a hexagonal head, used to secure the front lamp assemblies and their mounting plates to the chassis. It provides reliable clamping force under vibration.

These bolts are available in various lengths (M8x20, M8x22, M8x16, etc.) and are made of grade 8.8 steel with a zinc plating for corrosion resistance. They are used in conjunction with flat and spring washers.

For the front lamp installation, hex bolts are the primary fasteners that hold the headlight bracket and the connecting plate. Proper torque ensures that the lamp remains aimed correctly.

Isha pe Hexagonal nut

The Isha pe Hexagonal nut (type 1) is a standard hex nut that pairs with hex bolts to create a secure threaded joint. It is manufactured to precise tolerances.

These nuts are used in sizes M8 and M6, often with a spring washer underneath to prevent loosening. They are essential for the lamp mounting plate and connecting plate.

The zinc-plated finish provides excellent protection against rust, ensuring that the nut can be removed even after years of service without seizing.

Flat washer

The Flat washer is a plain annular disc used under bolt heads and nuts to distribute the clamping load evenly over a larger surface area. This prevents damage to the lamp housing or bracket.

These washers are available in sizes M5, M6, and M8, and are made from low-carbon steel. They are often used together with spring washers to create a vibration-resistant joint.

For the front lamp installation, flat washers are placed under the bolt head and nut to protect the painted surfaces of the mounting plate and connecting plate.

Spring washer

The Spring washer (also known as a split lock washer) provides a locking action that prevents bolted joints from loosening due to vibration and shock loads. It exerts a constant spring force.

These washers are used in sizes M4, M5, M6, and M8, and are made of spring steel with a protective coating. They are critical for the front lamp assembly, which experiences constant road vibrations.

When used with a flat washer, the spring washer ensures that the bolt remains tight over the long term, maintaining the correct headlight aim and preventing rattling.

Cross crew (cross recessed screw)

The Cross crew is a pan-head screw with a Phillips drive, used for attaching light covers, trim pieces, and small brackets. It is commonly used in the front lamp area.

This screw is available in M6x20 and other lengths, with a zinc-plated finish. It is often used with a flat washer and spring washer to ensure a secure fit.

The cross recess allows for easy installation with a standard screwdriver, making it convenient for assembly and disassembly during maintenance.

Front lamp installation plate

The Front lamp installation plate is a precision-stamped metal bracket that holds the headlamp assembly in place. It provides the correct positioning for the lamp’s beam pattern.

This plate features pre-drilled holes for bolts and nuts, and it is designed to absorb minor shocks without distorting. It is made from galvanized steel for corrosion resistance.

The installation plate also serves as a protective shield for the lamp’s rear housing, preventing damage from road debris. It is a critical component for a durable lighting setup.

Connecting plate

The Connecting plate is a secondary bracket that links the front lamp installation plate to the chassis frame. It adds extra rigidity and helps distribute the weight of the headlamp.

This plate is made from high-strength steel and is designed to fit the specific contours of the HOWO A7 8X4 front end. It ensures that the lamp stays aligned even on rough roads.

The connecting plate uses hex bolts and washers for attachment, and it provides additional mounting points for wiring clips and other accessories.

LHex bolt

The LHex bolt is a hexagon head bolt with a slightly different head shape or length specification, used in specific mounting points where a standard hex bolt may not fit.

It is typically used for attaching the connecting plate to the chassis or for securing the installation plate in tight spaces. Its dimensions are precisely matched to the application.

Like other bolts, it is supplied with a corrosion-resistant coating and is used with appropriate washers and nuts to ensure a reliable, long-lasting fastening.

Understanding the Front Lamp Mounting System

The HOWO front lamps assembly is not just about the light units themselves; it relies on a robust mounting structure to maintain correct aim and prevent vibration damage. The installation plate and connecting plate work together to create a rigid foundation.

All bolts and nuts used in this system are metric, with thread sizes M6, M8, and sometimes M10. The use of spring washers under every nut and bolt head ensures that the clamping force remains constant even after thousands of kilometers of rough roads.

The flat washers protect the painted surfaces of the plates and prevent galvanic corrosion between dissimilar metals. This attention to detail is what makes genuine HOWO parts superior to generic hardware store alternatives.

Regular inspection of the mounting hardware is recommended, especially after off-road use. Loose bolts can cause the headlight to wobble, reducing visibility and annoying other drivers.

Installation and Torque Guidelines

Start by attaching the connecting plate to the chassis frame using the M8 hex bolts, flat washers, and spring washers. Torque these bolts to 25–30 N·m to ensure a secure fit without overstressing the threads.

Next, mount the front lamp installation plate to the connecting plate using the M8 bolts and nuts. Use the Isha pe Hexagonal nuts on the backside, with a spring washer under each nut. Torque to 20–25 N·m.

Attach the headlamp assembly to the installation plate using the smaller cross screws (M6) and flat washers. Do not overtighten these screws, as they thread into plastic or die-cast lamp housings – 8–10 N·m is sufficient.

After installation, check the beam alignment using a wall or screen. Adjust if necessary by slightly loosening the mounting bolts and repositioning the lamp. Always retighten all fasteners after adjustment.

For models with left and right lamps, note that the mounting plates may be side-specific. Always refer to the vehicle’s service manual for the correct orientation.

Compatibility and Cross-Reference

These HOWO front lamps hardware parts are designed specifically for the HOWO A7 8X4, but many of the fasteners (hex bolts, washers, nuts) are standard metric components that can be used on other HOWO models or even other heavy trucks with similar mounting points.

The installation plate and connecting plate, however, are chassis-specific. They are shaped to match the unique contours of the A7 8X4 front end, so they should not be interchanged with parts from other models.

When ordering, always verify the part numbers against your truck’s VIN or original equipment list. Using the wrong plate can lead to poor headlight aim and potential failure of the lamp due to stress.

For the cross screws, they are a common size (M6x20) and can be replaced with equivalent screws from other manufacturers, but we recommend using genuine parts for the best thread engagement.

Long-Term Reliability and Safety Benefits

Properly secured HOWO front lamps are essential for road safety. A loose headlight can cause glare for oncoming traffic and reduce the driver’s forward visibility, increasing the risk of accidents.

By using genuine hardware, you avoid the common issue of stripped threads or snapped bolts, which can happen with low-quality aftermarket fasteners. This saves you from costly repairs and downtime.

The corrosion-resistant coatings on our bolts, nuts, and washers mean they will not rust and seize, making future lamp replacements or bulb changes much easier. This is a significant advantage for fleet maintenance.

Moreover, the precise fit of the installation plate ensures that the headlight beam pattern meets legal requirements, preventing fines and ensuring your truck passes inspection.

We recommend keeping a spare set of bolts and washers in your emergency kit, as they are small and inexpensive but can be crucial when a headlight needs quick attention on the road.
