The Timco M8 x 150mm A2 Stainless Steel Carriage Bolts are designed for construction professionals and DIY enthusiasts who require secure, weather-resistant fastening for timber projects. These bolts provide exceptional holding strength for attaching ironmongery or clamping large timber sections together. The primary benefit is their superior resistance to corrosion, making them ideal for outdoor environments; however, users should note that stainless steel requires careful handling to prevent thread galling during installation.

While A2 stainless steel offers excellent corrosion resistance, for coastal or high-salinity areas, A4 (Marine Grade) stainless steel is generally preferred.
No, you only need to drill a circular hole for the shank. The square shoulder is designed to be pulled into the timber by the pressure of tightening the nut.
Yes, these specific M8 x 150mm bolts are fully threaded along the shaft.
The pack contains the bolts; please check your specific product packaging as nuts are often sold separately or specified in the contents list.
A2 stainless steel is naturally resistant to rust without needing a protective coating that could chip or wear away over time.
The square shoulder is not fully seated. Use a hammer to tap the head firmly into the wood until the square section locks.
This is likely thread galling. Back the nut off, clean the threads, apply a thread lubricant, and tighten slowly.
For proper installation, drill a hole slightly larger than the 8mm shaft diameter. To engage the anti-spin shoulder, gently tap the bolt head with a mallet until the square neck is fully embedded into the wood. When using stainless steel, it is highly recommended to apply a lubricant to the threads before tightening, as this prevents the metal from seizing (galling) due to friction. Always use a matching A2 stainless steel nut and washer to ensure galvanic corrosion does not occur between dissimilar metals. After installation, no ongoing maintenance is required, though periodic inspection of the torque is advised for safety-critical structures.
