Hex Bolt Sleeve Anchor With Red Nylon With DIN125: This type of anchor combines a hex - bolt design with a red nylon element, adhering to the DIN 125 standard. Constructed from carbon steel (available in grades such as 4.8, 8.8, 10.9) and usually zinc - plated to enhance corrosion resistance, the red nylon part serves multiple purposes. It reduces friction during installation, allowing for easier tightening of the hex bolt, and also helps to improve the grip and stability of the anchor within the drilled hole. Ideal for a wide range of applications including construction projects, industrial machinery installations, and heavy - duty equipment mounting, it provides a reliable and sturdy fastening solution.

Instructions for Use：

Mark the position on the substrate where you want to install the anchor. Then, use an appropriate drill bit to create a hole with the correct diameter and depth according to the anchor's specifications. Clean the hole thoroughly to remove any debris. Insert the hex bolt anchor into the hole until it is fully seated. Use a wrench to tighten the hex bolt. As the bolt is tightened, the anchor body inside the hole will expand, gripping the inner walls of the hole tightly, forming a secure attachment. Avoid over - tightening to prevent damage to the substrate or the anchor itself.
