The choice of M20 foundation bolts is influenced by several factors. These include the weight and type of machinery, the expected dynamic loads, and the soil conditions at the site. The M20 bolt, due to its medium-large size, offers a good balance between strength and ease of installation The M20 bolt, due to its medium-large size, offers a good balance between strength and ease of installation

- Spark plugs are designed with a central electrode and a side electrode, separated by a tiny gap. When voltage from the ignition system jumps this gap, it creates a spark, which in turn ignites the compressed fuel and air inside the cylinder. This ignition triggers a controlled explosion, driving the piston down and ultimately turning the vehicle's wheels or performing whatever task the machine is designed for.
The metal used in the outer case of oil seals is usually made of carbon steel. Upon request, and depending on quantities, a different type of steel (such as stainless steel) can be used.
- 2. Thickness One of the defining characteristics of thick rubber gaskets is their thickness, which can vary from a few millimeters to several centimeters. This thickness provides additional support and protection against pressure and abrasion, making them ideal for high-pressure and heavy-duty applications.
Standard springs are made of carbon steel. We use stainless-steel springs for our GR and GRST oil seals made from FKM rubber. In some rare cases, an O-ring is even used as a spring element. Standard PTFE lip seals are not fitted with springs.
The electric circuit sheath is one of the key materials that can not be replaced in the defense advanced
