صواميل سداسية 5/18-11 | فولاذ مؤكسد أسود (50 / عبوة)

Grabbed a pack for a project in the garage, and these black oxide nuts got a nice, non-reflective finish that blends in well with the steel bolts. They threaded on smoothly with no cross-threading, and the 50 count is plenty to finish the job with spares.

Threaded them onto some 5/16"-11 bolts for a cart repair, and every single nut spun on smoothly right out of the bag. The black oxide coating gives them a nice, uniform look without any rough edges.

The black oxide finish on these is a nice touch—they don’t glare under work lights like plain steel. Threads caught cleanly on the bolts I used, and having 50 in one packet means I won’t run out mid-project.
