براغي آلية #4-40 × 1/4 بوصة | رأس مسطح مع محرك فيليبس | فولاذ أسود مؤكسد (8000/عبوة)

The black oxide finish on these #4-40 screws gives them a clean, even look that resists glare under shop lights. I've already used a couple hundred on control panel covers and they seat flush without stripping the phillips head. The 8000-count box means I won't restock for years.

Pulled out a handful to fasten a small metal enclosure and every single one seated cleanly without stripping. The flat head sits flush and the phillips drive grabs the bit nicely. For an 8000-count box, this is a solid buy.

The black oxide coating on these screws looks clean and should resist rust well inside the control panel I’m assembling. Each one threads smoothly into the pre-tapped holes without any binding.
