براغي تثبيت برأس مخروطية #4-40 × 5/32 بوصة | فولاذ سبائكي (250 / عبوة)

I was tired of stripping softer screws in tight spots, but the hex socket drive on these #4-40s grabs securely even with a tiny Allen key. The cone point centers perfectly into the divot, making adjustments on my small fixtures a breeze.

The hex socket drive is a lifesaver when adjusting these tiny screws in cramped equipment. The alloy steel feels solid and durable for the price, and the whole package of 250 will last me years.

The cone point on these #4-40 screws bites into the shaft perfectly without walking around during installation. For such a small fastener, the hex socket gave me plenty of grip to torque them down securely in a tight spot.
