7/8-9 × 1-3/4" براغي مقبس نقطة كوب | فولاذ سبائكي (25 / عبوة)

I needed a set screw for a heavy-duty static application, and these are solid and machined well. The cup point bit into the shaft nicely and hasn't budged under load.

The hex socket drive made installing these in a tight spot on my machine much easier than a standard slotted screw. The cup point really digs in and holds firm once torqued down.

The hex socket drive made tightening these in a cramped gearbox far easier than wrestling with a wrench, and the cup point bit into the shaft cleanly without slipping. Alloy steel feels solid, and the 25-piece count is plenty for my current batch of repairs.
