expansion bolts for hollow structural steel sections

The 38mm length is a popular choice for several reasons. This size is ideal for applications where a deeper penetration into the framing is required, providing increased structural stability. The longer length allows the screw to anchor firmly into the stud or beam, ensuring the drywall remains securely fastened. It is particularly useful in situations where thicker drywall or multiple layers are being installed, as it can penetrate through the drywall and engage the substrate effectively.

While not fasteners in the traditional sense, washers are often used in conjunction with bolts, nuts, and screws to improve their performance. Washers distribute the load of the fastener over a larger surface area, helping to prevent damage to the material being fastened and reducing the risk of loosening due to vibration. There are several types of washers, including flat washers, lock washers, and fender washers, each serving specific functions in various applications.

One of the key advantages of self-drilling screws for heavy steel is their ability to save time and labor costs. Traditional screws require pre-drilling a hole before fastening, which can be time-consuming, especially when working with heavy steel materials. Self-drilling screws eliminate the need for this extra step, allowing for quick and efficient installation. This is particularly important in industrial settings where production timelines are tight and every minute counts.

The installation process of an M12 chemical anchor involves drilling a hole into the substrate to the appropriate depth, then filling it with a specially formulated two-part resin. The anchor bolt is then inserted into the resin while it's still pliable, and as the resin cures, it forms a tight grip around the bolt, creating a robust connection. The curing time varies depending on the specific chemical composition of the resin, ambient temperature, and humidity.
