Coach bolts, also known as carriage bolts, are a type of fastener characterized by a rounded head and a square or slightly tapered neck under the head. This design prevents the bolt from turning once inserted into a pre-drilled hole. This makes them particularly suitable for applications where rotation needs to be prevented, such as securing wooden components or connecting metal parts.
China coach bolts are manufactured in a wide range of materials, including carbon steel, stainless steel, and alloys. They are available in various sizes, measured by diameter and length, with different finishes like zinc plating, hot-dip galvanizing, or powder coating to enhance corrosion resistance. The choice of material and finish depends heavily on the intended application and the operating environment.
China coach bolts are widely used in a variety of applications across various industries. Common uses include:
When sourcing China coach bolts, it's crucial to prioritize quality and reliability. Here are some key factors to consider:
Thoroughly research potential suppliers. Check their certifications (e.g., ISO 9001), manufacturing capabilities, and customer reviews. Consider working with established companies with a proven track record of delivering high-quality products. A reliable supplier will offer transparency in their manufacturing processes and provide detailed product specifications.
Request samples and conduct thorough inspections to verify that the China coach bolts meet your required specifications. Look for any signs of defects, such as cracks, imperfections, or inconsistencies in dimensions. Consider using third-party inspection services to ensure unbiased quality control.
Compare prices from multiple suppliers, but avoid selecting solely based on the lowest price. Consider the overall value proposition, including quality, reliability, and customer service. Negotiate favorable payment terms and clarify delivery timelines.

| Material | Strength | Corrosion Resistance | Cost |
