HOLO-KROME 61008 #10-32 X 3/4" 內六角螺絲 | 平頭內六角驅動 | 合金鋼 熱處理黑氧化 (100顆/包)

The hex socket drive makes installing these in tight jig spaces so much easier than using a standard driver. The flat head sits flush and the black oxide coating looks clean on my tooling setup.

The black oxide finish on these screws looks sharp and held up fine when I tightened them into a jig fixture. Threads engaged cleanly with no binding, and all 100 in the pack were consistent. Good solid hardware for assembly work.

The flat head sits perfectly flush when countersunk, which made setting up a precision fixture a breeze. Threads started clean without any galling on the alloy steel, and the black oxide finish survived a few knocks without chipping.
