4. Load Capacity The load-bearing capacity of an M20 foundation bolt can vary depending on the grade of steel used. Common grades include 4.6, 8.8, and higher grades, with 8.8 indicating a high-strength bolt capable of bearing significant tensile and shear loads.

One of the most prominent features of the 7% 2016 self-drilling screw is its efficient design. The screw's drill point is engineered to penetrate metal sheets and other materials with ease. The 7% design typically refers to the thread pitch and size, which ensures a superior grip and locking mechanism. This makes the fasteners particularly effective in holding tight under various conditions.

1. Strength and Durability Due to the high-strength material used in their production, M20 bolts can bear heavy loads without deforming or failing, making them ideal for critical structural applications.

Drywall screws are specialized fasteners designed for affixing drywall sheets to wooden or metal studs. Unlike regular screws, drywall screws are engineered to prevent tearing of the drywall paper and to provide superior grip. They typically feature a bugle head that reduces the risk of tearing and a sharp drill point that makes installation easier. The market offers various types of drywall screws, including coarse-thread screws for wood and fine-thread screws for metal.

 In addition, the bolt complies with industry standards such as ASTM A325 and A490, ensuring that it meets the necessary requirements for steel structural connections. Its compatibility with these standards makes it the first choice for engineers and contractors who prioritize quality and performance.

In the construction and engineering fields, the strength and reliability of fasteners are critical. That’s why we are pleased to introduce new DIN6914/A325/A490 heavy-duty hex structural bolts to the market. This high-quality bolt is designed to provide superior strength and durability for heavy-duty applications on steel structures.
