Needed a solid batch for a precision assembly at work, and these cap screws fit perfectly with zero wobble. The black oxide finish also seems to hold up well against oil and chips.

Installing these on a jig fixture was straightforward; the hex drive engaged cleanly without any cam-out. The black oxide finish also held up well against the oily shop environment.

These came in handy for a precision assembly project I was working on — the black oxide finish gives them a nice, uniform look and the hex socket drive made installation a breeze. Exactly the length I needed for the job.
