Here it is rewritten into a clear paragraph format 👇

High-quality M12 x 220mm coach bolts (carriage bolts) manufactured to DIN 603, supplied complete with full nuts and Form A washers. These bolts are finished in bright zinc plated (BZP) steel, providing good resistance to corrosion and oxidation. They are ideal for strong and secure fixing across a range of materials including wood, metal, and plastic.

Designed for durability and ease of use, the square neck beneath the rounded head prevents rotation during tightening, allowing for a secure and reliable installation. These bolts are intended for use with spanners or sockets, ensuring maximum torque and a firm hold in a variety of applications.

Suitable for general industrial, construction, and DIY use, these coach bolts are commonly used in timber structures, fencing, machinery assembly, and other fastening tasks where strength and reliability are required. The zinc-plated finish offers protection in standard environments; however, they are not recommended for marine or highly corrosive conditions.

Manufactured from grade 4.8 carbon steel, these bolts are designed for general-purpose fastening and are not intended for high tensile or structural applications where higher strength grades are required.
