4. Load Capacity Chemical anchors are rated for both tensile and shear loads. The specifications should clearly state these values, often tested according to specific standards such as ASTM or EN to ensure reliability.

Metal expansion nuts, often referred to as expansion anchors or expansion inserts, are specialized fasteners that expand when a bolt or screw is threaded into them. They typically consist of a cylindrical body with slits along its length or an expandable design that facilitates outward expansion. The main purpose of these nuts is to create a secure grip within a substrate, such as concrete, wood, or metal, thereby preventing loosening due to vibrational forces, temperature fluctuations, or stress.

Moreover, DIY enthusiasts use self-drilling screws in home repairs and renovations due to their user-friendly nature. Whether it's installing a shelf or building a garden shed, these screws are invaluable for ensuring a reliable and robust assembly.

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.

- Environment The operating conditions, including exposure to moisture, chemicals, or high temperatures, can affect the performance of anchor bolts. Sometimes, specialty coatings or materials may be needed for enhanced durability.
