A325 fasteners are heavy hex structural bolts that conform to the specifications set forth by the American Society for Testing and Materials (ASTM). These fasteners are primarily used in conjunction with A325 nuts and are designed to create bolted connections in steel structures, providing robust and durable performance under various loads and environmental conditions.

What Are Self-Drilling Screws?

While 16mm self-drilling screws offer numerous advantages, there are some considerations to keep in mind

3. Industrial Equipment Heavy machinery and equipment in industrial settings often require strong anchoring solutions, where M20 foundation bolts are tested and proven to provide the necessary stability.

The integrated wrench flats provide another significant advantage. These flats enhance ease of use, allowing for more efficient installation and removal processes. By providing a surface for easy gripping, they minimize the risk of hand slippage, which can lead to injuries or damage to the components being fastened. Moreover, they prevent rounding of the stud while under load, ensuring a longer lifespan and better maintenance of the connection’s integrity.

The M in M20 signifies that it is a metric bolt, aligning with the International System of Units (SI). The number 20 denotes that the nominal diameter of the bolt is 20 millimeters. Foundation bolts are typically made from high-strength materials, such as structural steel, to ensure they can withstand substantial loads and resist environmental factors.
