FAQS on 12mm coach bolts

Common Queries About 12mm Coach Bolts and Related Fasteners

Q: What are 12mm coach bolts typically used for?

A: 12mm coach bolts are ideal for securing wood-to-wood connections, such as in timber framing or furniture. Their square neck prevents rotation during installation, and the domed head provides a finished look.

Q: How do 12mm countersunk bolts differ from coach bolts?

A: Unlike coach bolts, 12mm countersunk bolts have a flat, angled head that sits flush with the material surface. They’re often used where a smooth finish is required, such as in cabinetry or metalwork.

Q: Can 12mm dyna bolts be used in concrete?

A: Yes, 12mm dyna bolts (mechanical anchors) are designed for concrete or masonry. They expand when tightened, creating a secure hold for heavy-duty fixtures like shelves or structural brackets.

Q: Are 12mm coach bolts suitable for metal applications?

A: Coach bolts are primarily designed for wood due to their square neck grip. For metal, consider 12mm countersunk bolts or dyna bolts paired with appropriate anchors for better stability.

Q: Do 12mm dyna bolts require pre-drilled holes?

A: Yes, 12mm dyna bolts need a pre-drilled hole matching their diameter and depth. Proper alignment ensures the anchor expands correctly, providing maximum load-bearing capacity.
