1/4-28 X 1-1/4" 半狗點內六角螺絲 | 合金鋼 (100個/包)

The hex socket drive made seating these in a cramped bracket way easier than wrestling with a slotted screwdriver, and the half dog point seated perfectly into the mating hole. All 100 arrived clean and threaded smoothly, no burs or duds in the batch.

These little screws hold tighter than I expected in my jig setup, and the hex socket lets me wrench them down without stripping. The half dog point seats perfectly in the dimple, no wobble at all.

The half dog point makes alignment so much easier during assembly, and the hex socket drive lets me get full torque without stripping. These 1/4-28 screws held perfectly in a tight jig setup I’ve been working on.
