1/4-20 x 3/8" 기계 나사 | 접시 머리 슬롯 드라이브 | 일반 강철 (1,200 / 팩)

I bought these for a quick workbench project and the flat head sits perfectly flush every time—no binding or stripping. 1,200 screws in one package is exactly what I needed to stock my shop without constant reordering.

I’m replacing mismatched fasteners on an old workbench and these 1/4-20 by 3/8" flat heads fit perfectly into pre-tapped holes.

For a bulk pack of plain steel screws, these are exactly what I needed for assembling jigs in my workshop. The 1/4-20 threads catch cleanly in pre-tapped holes, and 1,200 pieces in one package means I won’t run out mid-project.
