Designed for builders, carpenters, and DIY enthusiasts, these TIMco Carriage Bolts are the ideal choice for securing timber components and heavy-duty ironmongery in outdoor or marine environments. Crafted from high-grade A2 stainless steel, they provide exceptional resistance to rust and corrosion, making them perfect for long-term exterior use; however, it is important to note that matching nuts are not included with this pack and must be purchased separately.

No, this specific pack includes only the carriage bolts; matching M8 nuts must be purchased separately.
Yes, A2 stainless steel is recommended for Green Oak due to the high acidity levels inherent in the timber which can corrode other types of fasteners.
These bolts have a metric thread diameter of M8.
While A2 stainless steel has excellent corrosion resistance, for extreme marine or salt-spray environments, A4 (Marine Grade) stainless steel is typically recommended. A2 is sufficient for most general exterior use.
Yes, these 60mm bolts are fully threaded.
The square shoulder is designed to embed into the wood, acting as a lock to prevent the bolt from turning while you tighten the nut with a wrench.
The square shoulder has not seated fully into the timber. Use a mallet to strike the head of the bolt firmly to force the square neck into the wood fibers.
Ensure the pilot hole is at least 9mm in diameter to account for the bolt shank width, and check for wood debris inside the hole.
To install these carriage bolts, drill a clearance hole slightly larger than the M8 shank (typically 9mm). Insert the bolt through the timber and tap the dome head gently with a mallet until the square shoulder bites into the wood. This bite is essential to keep the bolt from spinning while you tighten your M8 nut from the other side.
Because these are stainless steel, avoid using standard carbon-steel tools to drive or tighten them if possible, as cross-contamination of metal particles can lead to 'tea staining' or surface rust. Always use stainless steel or galvanized nuts to avoid galvanic corrosion, and note that these bolts are fully threaded at 60mm, making them suitable for thin-to-medium thickness timber connections.
