Technical Superiority of Galvanised Coach Bolts

Our hot-dip galvanised coach bolts
outperform standard fasteners with:

1,200+ hours salt spray test resistance
55-85µm zinc coating thickness (ASTM A153 standard)
M8 to M24 sizing flexibility
450 MPa minimum tensile strength

Want bolts that laugh at acid rain? Our triple-coating process creates a zinc-iron alloy layer 3X denser than electroplated alternatives.

FAQS on galvanised coach bolts

Q: What are the key differences between galvanised coach bolts and galvanised coach screws?

A: Galvanised coach bolts feature a smooth domed head and square neck to prevent rotation, while galvanised coach screws have a threaded sharp tip for self-tapping into materials. Both provide corrosion resistance through zinc coating.

Q: Can galvanised countersunk bolts be used for outdoor timber projects?

A: Yes, galvanised countersunk bolts are ideal for outdoor timber applications due to their weather-resistant zinc coating. Their flat heads sit flush with surfaces, ensuring a clean finish in structures like decks or fences.

Q: Do galvanised coach screws require pre-drilling before installation?

A: While not always mandatory, pre-drilling pilot holes for galvanised coach screws reduces wood splitting and eases installation in hardwoods. The self-tapping design allows direct insertion in softer materials like treated pine.

Q: How does galvanisation improve the durability of coach bolts?

A: The galvanisation process applies a protective zinc layer to coach bolts, preventing rust and corrosion. This makes them suitable for humid or wet environments, extending their lifespan compared to uncoated alternatives.

Q: Are galvanised countersunk bolts suitable for metal-to-wood connections?

A: Yes, galvanised countersunk bolts work well for metal-to-wood joints, especially when securing brackets or plates. Their flat heads distribute pressure evenly, while the zinc coating prevents galvanic corrosion between dissimilar materials.
