Hex Bolt, Scn435/Black Oxide Film) All Screw Thread M20x40

It is inexpensive and the quality is also good, I purchase it every time as a repeat item.

Use the threaded flange as a taper and use it. I was prepared for variations in quality because the price was cheap As for the chuck in processing as well as the dimensions after processing I am satisfied with no problem at all.

I fixed it with this screw from the rotor shape of Ducati. I have strength, and I use it because black fits the design of rotor.

It is the best in COSPA. I think compatibility with nut is also good, strength and accuracy are also good.

I think that it is polite, firm and very good product.

Mounting of protection cover of machine & screws & purchase as replacement part of car body fitting screw of radio control of hobby, since it is a hexagon socket head bolt, it can be gripped with pliers wrench and nipper etc. on the outside so it is not inconvenient for loosening so use it I will.

For the height adjustment, I bought a spacer, but the head of the bolt attached is 5 mm in hexagon and it seems like licking when applying normal torque, so if you look for it, those with strength 12.9 and hexagon 6 mm (the same specification as RECARO genuine) are monotalou And it changed cheaply. There was similar to the appearance in the home center, but strength is unknown. Since it is the installation of the sheet to deposit the life, this product written tightly to the strength was safe and very good.

It was saved by the size perfect for fitting the RB 26 engine plug cover.

It's quite oily, so I use gloves when I use it. Although it can not be helped because of the nature of the product, it is a little dirty feeling.

It was very reasonable to use without any inferior to original genuine parts.
