#4-40 X 5/8" براغي مقبس بيضاوية الرأس | فولاذ سبائكي (250 / عبوة)

The hex socket drive grips the Allen key with zero wobble, so torquing these little #4-40s into a tight spot is surprisingly effortless. I've already used a dozen for a jig build and the oval points seat cleanly every time. For a 250-count box, these are a solid value.

These set screws are perfect for fine-tuning a micro-adjustment jig I built; the oval point seats nicely without marring the shaft. The hex socket drive lets you really crank them down in a tight spot.

The hex socket drive made seating these in a tight spot on my mill’s way wipers a breeze—no stripped heads, even with a short wrench. The oval point seated right into the existing dimple without walking. Solid little screws for the price.
