Product Description

The Big head carriage bolt M6*12, also known as M6*12 large head bolt or Heavy duty carriage bolt M6x12, is a durable fastening component designed for structural applications requiring high load capacity and stability. It features a domed circular head with a square neck to prevent rotation during installation, compatible with M6 threaded nuts and pre-drilled surfaces. The bolt measures 6mm in diameter and 12mm in length, made of high-strength carbon steel or corrosion-resistant stainless steel. Ideal for construction, machinery, and automotive industries, it operates reliably across temperatures from -30°C to 120°C and withstands harsh environments. Key advantages include vibration resistance, secure grip, and easy assembly, though precise pre-drilling is required for optimal performance. Surface treatments like zinc plating enhance durability against wear and rust.
