HOLO-KROME 86424 #10-24 X 1/4" 內六角螺絲 | 六角套筒驅動 | 合金鋼 熱處理黑色氧化 (100個/包)

I needed a batch of fasteners for a small tooling repair, and these cap screws fit perfectly with no stripped threads. The black oxide finish looks durable and the hex drive engaged cleanly every time.

For a precision fixture I was building, these #10-24 screws seated perfectly in the hex drive without any stripping, and the black oxide finish makes them look clean on the tooling. The 100-count pack means I’ve got plenty left over for future adjustments.

I needed a small batch for a jig repair and these fit the countersunk holes perfectly. The hex socket drive grabs well without stripping, even with my cheap Allen keys.
