M20 chemical anchor implantation depth
The implantation depth of chemical anchor bolt m20 is usually 12-14mm, which is calculated based on the anchor depth calculation formula D = (0.6-0.7)d, where D is the anchor depth and d is the bolt diameter.
Features of M20 chemical anchor bolts:
1. Easy installation and low cost;
2. No expansion force is generated, strong pull-out force, fast load-bearing, vibration-resistant, fatigue-resistant, and aging-resistant;
3. Adopts new materials, acid and alkali-resistant, safe and environmentally friendly;
4. Can be used normally at negative temperatures;
5. High-strength chemical anchor bolts are made of chemical agents (glass tubes) and metal rods (high-quality carbon structural steel or stainless steel).
