Customer Reviews of Hex-Socket Set Screw

It is used for positioning mechanical parts. I was looking for a short size and found it. There is no problem in use.

The length is perfect and it is very good. It was the product I expected.

It is a very good product with very beautiful finish and high accuracy.

Actually I wanted a stainless steel screw, but since it was not, I replaced it with a plated product. Please also line up with stainless steel.

Apart from quality, this product image will be the source of mistake purchase. From the color of the image, I thought that it was a trivalent black product and purchased it. Those who did not read well are bad, but I hope you will forgive misleading images.

"To use it as a flat set screw, you can not use it unless the center of the tip is dented and you need to do a bit of processing." - The center of the tip is dented 0.1 mm + alpha. It is slightly better than the tip of an ordinary hexagon bolt. It seems that the outer circumference of the tip has been raised by rolling the cut-off material with a special shear or rolling the material with a small chamfer. As it is quenched with cromoli, it can be used if you grab it on a drilling machine or a chuck on some rotating machine and repair it with a diamond file. - It would be worthwhile to buy three at this price, but there is a difficulty in selling it as "Hexagon socket set screw flathead" with non-face-to-face mail order. To say "this kind of" from the price, I think that some supplement is required as it is by name or description of item.
