How to choose spanner specifications
Preferred steel, strong and durable, complete specifications
Selection range
Figure: The diameter of the nut at the wrench bayonet can be selected within the range.
For example, if the outer diameter of the nut is 50mm, a crescent wrench with a bayonet range of 45-52 is optional.
(You can choose a larger wrench so that the curve is more curved and easier to unscrew the nut)
Conventional Spanner
Adopting advanced quenching process, it has high surface hardness, strong fatigue resistance and long service life.
The surface is electroplated and has high corrosion resistance and high wear resistance.
After heat treatment, the hardness reaches 44-48 HRC and the rigidity is high.
Hardened Spanner
Made of high-quality hard steel, the clamping position is accurate and the teeth will not slip.
Longer service life, surface passivation treatment, high corrosion resistance, no rust
The surface is frosted, feels comfortable and does not hurt your hands
Thing to note when Use A Spanner
Spanner are used to adjust rings, lock nut rings and bearings. Specifically designed to withstand the toughest industrial use.
This spanner is not suitable for use on hydraulic cylinders
Do not hit the end of the spanner with a hammer, otherwise it will cause the wrench head to crack, so it is improper use.
Measure the outer diameter of the round nut. For example, the diameter is 70mm. Available sizes are 68 72 or 78-85. You can choose a slightly larger wrench (78-85) so that the curvature of the ring is larger, making it easier to unscrew the nut.
