Frequently Asked Questions
Q:
What is the primary advantage of the carriage bolt's square neck?
The square neck is designed to lock into a pre-drilled square hole or grip into wood, which prevents the bolt from turning when the nut is being tightened. This allows for easy installation from one side.
Q:
Can these bolts be used in marine or coastal environments?
Yes, our bolts made from high-grade 304 or 316 stainless steel offer exceptional resistance to salt spray and corrosion, making them ideal for shipbuilding and coastal hardware applications.
Q:
Are these bolts compatible with standard nuts and washers?
Absolutely. Our carriage bolts feature precision-machined threads that are fully compatible with standard metric or imperial nuts and washers, ensuring a secure and reliable fit.
Q:
Do you offer customization for specific lengths or sizes?
Yes, we provide a wide range of standard specifications and also offer customizable length options to meet the specific requirements of your engineering or furniture projects.
Q:
What kind of surface treatment do these bolts undergo?
Our stainless steel carriage bolts undergo a professional passivation treatment. This process removes surface contaminants and enhances the protective oxide layer, significantly improving rust resistance and durability.
Q:
Do these bolts meet international quality standards?
