Even though others have already been written. Hexagon seems to be licking even if I use Torque wrench and tighten with Torque prescribed.
It is true also with pure Normal Thread Screw, but this hex of Bolt is not a deep hole, so it may be easy to lick.
Considering things at the time of removal, too much attention is given to Screw lock.
If you are worried you might as well buy Steel from OEM Product.
It looks like GOOD because it is hard for Rust to look.
I was surprised to find out the price of OEM Product, I understood that this Stainless Steel is cheaper, I bought this ... ...
Hexagon's accuracy is very suspicious!
When prescribed Torque is applied, it seems that it does not eat firmly and a step mark remains.
It will be low accuracy & soft material.
This can not be reused.
List price 221 yen (tax included) As of November 2015.
★ This Stainless bolt
Actual unit price 260 yen (tax included)
Price is not so different, so here is my recommendation.
Because it is a combination of Stainless Steel and Aluminum
You better notice Overtorque.
Because it is a shallow HexagonalBolt!
I did not use it, but it would be good to tighten it with 20 Nm in combination with a Screw stopper.
Rustor bolt rust in Restore and exchange.
If your feet are beautiful, you will see it shrinking as a whole.
However, if you tighten a little more than the prescribed Torque, it will likely be licking.
Screw lock so it will not be a problem if you tighten with the prescribed Torque.
Although the price is a little expensive, I think whether to replace it after about 2 times use.
Various for Stainless Steel etc. There is a grade and it is not known how much this is the material, but if you tighten it with the prescribed Torque's 23 Nm, the Screw hole never collapsed.
Polished and it is beautiful.
By the way, Stainless Steel is not a material that does not rust, it is a rust resistant Material so it will be damaged if it remains dirty.
