Product description

M8 x 20 screw with 1.25 thread

Proper bolt strength selection should be made before installation, as bolt shape and technical parameters can directly impact the safety and durability of the connection. There are three bolt precision classes : A, B, and C, and 10 strength classes (measured in megapascals): 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8 , 9.8, 10.9, and 12.9, where the first digit indicates the tensile strength limit and the second indicates the yield strength relative to the first value (as a percentage). The higher the values, the greater the bolt's strength. 3.6 is the lowest quality bolt (made of low-carbon steel) and 12.9 is the highest strength class (made of low-alloy steel).

Questions & Answers

Why is regular filter replacement (oil, air, fuel) crucial for a mini tractor?

User
Ekspert Traktor.com.pl – Doradca techniczny • 17.02.2026
Regular filter replacement is the easiest way to extend the life of an engine from brands like Kubota or Yanmar. The oil filter removes metallic contaminants generated during operation, the air filter protects the cylinders from field dust, and the fuel filter prevents water and dirt from damaging the precision injection system. We recommend replacing filters every 50-100 operating hours or at least once per season to ensure optimal engine performance.

How to properly select and sharpen mower blades for a Japanese tractor?

When selecting mower blades, consider the mower deck model and the blade length and center bore diameter. Maintaining blade balance is crucial when sharpening – an unbalanced blade causes vibrations that damage the hub bearings. Remember that sharp blades mean healthier grass, a cleaner cut, and less strain on the engine of your Iseki or Mitsubishi tractor.

How to identify the correct V-belt size and how to care for it?

User
Ekspert Traktor.com.pl – Doradca techniczny • 17.02.2026
It's best to read the markings on the side of the old V-belt. If they are illegible, measure the belt width and its outer length (La). On Shibaura and Hinomoto tractors, it's important to regularly check the belt tension – too loose a belt will cause slippage and faster wear, while too tight a belt can cause alternator or water pump bearing failure.
