FAQS on carriage bolt with screw head

Q: What is a carriage bolt with a screw head?

A: A carriage bolt with a screw head combines a square neck beneath a domed head for anti-rotation and a threaded shaft. It is commonly used in wood-to-wood or metal-to-wood applications. The screw head refers to its compatibility with hex or wrench tools.

Q: Are coach bolts with screw head the same as carriage bolts?

A: Yes, "coach bolts" and "carriage bolts" are interchangeable terms. Both feature a square neck and domed head, designed to prevent spinning during installation. The screw head ensures compatibility with hex keys or wrenches.

Q: How does a hexagon head screw DIN 933 differ from a carriage bolt?

A: A DIN 933 hexagon head screw has a fully threaded shank and a hexagonal head for wrench tightening. Unlike carriage bolts, it lacks a square neck, making it unsuitable for anti-rotation applications. DIN 933 specifies dimensions and tolerances for standardization.

Q: Can carriage bolts with screw heads be used in automotive applications?

A: Yes, they are ideal for automotive assemblies requiring anti-loosening and anti-rotation. Their domed head and square neck ensure secure fastening in high-vibration environments. Ensure the material (e.g., stainless steel) meets corrosion resistance requirements.

Q: What tools are needed to install a hexagon head screw DIN 933?

A: A standard hex wrench or socket is used to tighten DIN 933 screws. Their hexagonal heads allow for high torque application. Always match the wrench size to the screw head’s specifications to avoid stripping.
