Home DIY improvement projects can be challenging, especially if you’re new to construction. However, with the right knowledge, techniques, and fasteners, you can complete your project successfully. When selecting fasteners, it’s vital to consider their strength compatibility.
For instance, when using a metric class 10.9 bolt, you should use a corresponding class 10 nut since it should always be stronger than the bolt. Additionally, you should consider the strength of your washers. This is because using heat-treated hex cap screws with non-heat treated washers can result in joint settling, causing a loss of clamp load.
