1/4-20 × 1-1/4" براغي إبهام | فولاذ مطلي بالزنك (2000 / عبوة)

The zinc plating on these thumb screws is holding up perfectly after several days of assembly work. I love being able to tighten them by hand without needing a tool each time.

The knurling on these thumb screws gives you a solid grip even with greasy fingers, which is clutch for repetitive assembly work. The zinc coating looks clean and uniform across all 2000 pieces, and they thread smoothly into my aluminum fixtures without any binding.

Bought a box of these for a project and they're exactly what I needed—the knurled head gives a solid grip, and the zinc coating hasn't chipped even after a few rounds of tightening with a wrench. For a bulk pack of 2000, the consistency in thread quality is impressive.
