1/4-20 × 2" 半狗點套件螺絲 | 合金鋼 (100入/包)

Finally, a set screw that actually grips. The hex socket drive let me torque these down in a spot where I couldn't even swing a wrench, and the alloy steel feels rigid enough to hold a heavy fixture without stripping. A hundred in the pack means I've got spares for every future project too.

The half dog point on these screws makes aligning them in tight spots so much easier than standard set screws. The alloy steel feels really solid, and all 100 in the package were clean and threaded perfectly.

I was a bit worried the hex socket would strip under heavy torque, but these alloy steel screws handled my project without a single issue. The half dog point made alignment in that tight corner way easier than I expected.
