5/16-18 X 2" 橢圓頭止付螺絲 | 合金鋼 (100 顆/包)

I needed a set screw that could really grip in a tight spot, and the oval point on these locks in place perfectly with the hex drive. They threaded cleanly into the hole without any stripping, and the alloy steel feels plenty durable for a heavy-duty adjustment. Exactly what I was hoping for.

I needed a screw that wouldn't strip out under heavy torque, and the hex socket drive on these handles that perfectly without any cam-out. They threaded smoothly into the alloy steel bracket I was mounting, and the 2-inch length was just right for a solid bite.

The oval point seated perfectly into the shaft’s center dimple, so it hasn’t backed out even with vibration. The alloy steel feels dense and the hex socket gave me a clean, snug grip without stripping.
