Moreover, electronics and manufacturing sectors frequently utilize washer head machine screws for securing casings and components. The precision fit and enhanced grip provided by these screws help maintain the integrity of electronic devices, ensuring they function correctly over time.

1. Wedge Anchors One of the most common types, wedge anchors feature a conical end that expands when the bolt is tightened. They are best suited for solid concrete and provide excellent load-bearing capabilities.

Additionally, chemical anchors offer versatility in installation. They can be used in a wide range of conditions, including cracked concrete and environments with variable temperatures. Furthermore, they significantly reduce the risk of spalling concrete, which can occur with mechanical expansion anchors, thereby preserving the integrity of the substrate.

2. Machinery Anchoring In industrial settings, M20 bolts are used to secure heavy machinery to concrete bases, ensuring stability during operation and minimizing vibration-related issues.
