This ensures that the connection remains secure even on the roughest roads, preventing intermittent faults that could compromise safety.

With the Trailer socket line, you can restore or upgrade your vehicle’s trailer electrical interface to factory-new condition, ensuring reliable communication with all trailers. Trust in HOWO’s engineering and the quality of this Trailer socket line to keep your truck and trailer operating safely and efficiently on every journey.

7-Core Trailer Plug (ISO 1185)

The 7-core trailer plug (ISO 1185) is a rugged, weatherproof connector that serves as the electrical interface between the tractor and trailer. It features seven high-current pins arranged in a circular pattern, with a positive locking mechanism that ensures a secure connection. This plug is the heart of the Trailer socket line, providing reliable transmission of lighting and control signals in accordance with international standards.

Manufactured from heavy-duty, impact-resistant plastic with gold-plated contacts, the 7-core trailer plug offers excellent corrosion resistance and low electrical resistance. Each pin is color-coded for easy identification, simplifying wiring and troubleshooting. The plug is designed to withstand extreme temperatures and exposure to road salts, oils, and UV radiation, ensuring long-term reliability in the Trailer socket line.

The 7-core trailer plug (ISO 1185) is compatible with all standard trailer sockets, making it a versatile choice for fleets that operate a variety of trailers. Its robust construction reduces the risk of intermittent faults, which are a common cause of trailer lighting failures. This plug is an essential component of the Trailer socket line, providing peace of mind on every trip.

Hexagon Bolt with Flange M8

The Hexagon bolt with flange M8 is a high-strength fastener used to secure the 7-core trailer plug’s mounting bracket to the vehicle chassis. Its integrated flange eliminates the need for a separate washer, providing a uniform clamping force that prevents the plug from shifting or vibrating loose during transit. This bolt is a key component of the Trailer socket line’s mounting system.

Manufactured from zinc-plated steel, the Hexagon bolt with flange M8 offers excellent corrosion resistance and durability. Its M8 thread size is standard for many heavy-duty applications, ensuring compatibility with existing mounting points on the HOWO Max 4X2. When used with the matching Hex flange nut M8, this bolt provides a secure and stable attachment for the Trailer socket line.

Proper torque application for this Hexagon bolt with flange M8 is essential for maintaining the integrity of the connection. The included bolt is pre-coated with a thread-locking compound to resist loosening due to vibration, a common feature of the Trailer socket line assembly.

Hex Flange Nut M8

The Hex flange nut M8 is the matching nut for the M8 bolt, featuring an integrated flange that distributes clamping pressure and prevents the nut from embedding into the mounting bracket. In the Trailer socket line, this nut works in tandem with the bolt to provide a secure, vibration-resistant fastening solution.

Made from the same zinc-plated steel as the bolt, the Hex flange nut M8 offers consistent corrosion protection and strength. The serrated face of the flange provides a positive lock against the bolt, preventing self-loosening even under severe vibration, which is essential for the reliability of the Trailer socket line.

The Hex flange nut M8 is designed to be used with a standard 13mm socket or wrench, making installation and removal straightforward. This nut, together with the bolt, ensures that the Trailer socket line remains securely attached throughout the vehicle’s operational life.

In the Trailer socket line kit, these fasteners are supplied in the exact quantities required, eliminating the need for additional hardware purchases. This attention to detail reflects the comprehensive design of the entire assembly.
