Similarly, aluminum bolts and screws are simply not suited for heavy-duty use, as they have low shearing resistance compared to steel and other metals commonly used as fasteners.

Moreover, a ductile metal like aluminum is highly prone to galling (or adhesive wear), where the aluminum nut under compressive force adheres to an aluminum surface, making later removal very difficult. For one thing, the yield strength is too low. Strong as it is, aluminum is rarely a suitable material for any kind of nut.

While our extruded aluminum profiles are up to the task in all these eventualities, the same cannot be said of aluminum fasteners.Īs you browse through our selection of aluminum fastener nuts, bolts, and screws, you will notice in the product specifications that none of them are actually made of aluminum. After all, depending on the type, size, weight, and material of the accessory you are attaching, these fasteners are likely to be exposed to considerable stress over time, undergo regular wear and tear, risk exposure to corrosive substances, and experience challenging weather events such as wind, rain, snow, extreme cold, and extreme heat. When choosing which type of accessories to attach to your Framing Tech aluminum fabrications, the first concern should be the strength, stability, and durability of the fasteners used.
