M4-0.7 x 8mm Socket Head Cap Screws Bolts, Class 12.9 Black Alloy Steel, DIN 912, Fully Threaded, 100 PCS

I purchased these as a replacement after I idiotically broke off one of the timing cover bolts on my roommates xs850 (Don't wrench tired kids!). They arrived in a timely manner, were well packaged, and were free of any burs or imperfections. All of them installed smoothly in the bike and torqued to spec without issue. Given the quality of these we will be picking up more to replace the other fasteners on the bike.

These are perfect, the coating did not instantly come off when the allen key made contact with them!

Bolts are new without any rust.

These are quality screws for a pretty good price. I ran out of this size in my assorted screw set, so I needed to replace them and this set was perfect for that. I have used several of the screws so far and they all appear to be well made and have worked great in my 3D printed projects. I have no complaints and would recommend this product.
