What size drill bit is needed for M20 chemical bolts?

M20 chemical bolts require a 25mm hole.

How big a hole should be drilled for an M20 chemical anchor?

m20 chemical anchor drill size require a 26mm hole‌.

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).
