1/4"-20 蓋形螺帽 | 鋼製黑色氧化處理 (100個/包)

I was pleasantly surprised by how smoothly these cap nuts threaded onto my bolts — no cross-threading at all. The black oxide finish gives them a clean, uniform look that matches my hardware nicely.

The threads on these cap nuts are perfectly clean and catch easily, which saved me time on assembly. The black oxide coating gives them a uniform, professional look that resists fingerprints. A solid choice for my metalworking projects.

The black oxide finish on these nuts looks sharp and resists fingerprints better than plain steel. Threaded a few onto some studs and they seated cleanly without any wobble or cross-threading. For a full bag of 100 at this price, it's hard to beat.
