3. Bonding Agent The type of chemical adhesive is crucial. Specifications should indicate the chemistry of the resin, curing time, and temperature range. Different projects may require different types of adhesives based on factors such as moisture exposure and load characteristics.

2. Corrosion Resistance Many manufacturers provide M20 bolts with coatings or treatments (like galvanization) to enhance corrosion resistance. This is vital for outdoor and industrial applications where exposure to moisture and chemicals is common.

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.

Metal expansion nuts serve as a vital component in ensuring mechanical integrity and stability in various applications. Their unique design allows for effective load management, self-locking capabilities, and adaptability to different materials and conditions. As industries continue to evolve, the role of metal expansion nuts will undoubtedly expand, contributing to the safety and efficiency of structures and machinery. Whether in construction, automotive, or other fields, understanding these fasteners' advantages can enhance engineering practices and promote better design solutions.

2. Cost-Effectiveness While they may be slightly higher in price compared to traditional screws, the longevity and reduced maintenance needs of galvanized Tek screws make them a cost-saving choice over time.
