7/8-9 X 4-1/2" 內六角螺絲 | 六角驅動 | 18/8 不鏽鋼 (10 顆/包)

The hex socket drive seated the Allen wrench perfectly with zero wobble, and the 18/8 stainless finish looks clean on my jig. They’re a solid fit for precision assembly work, though I wish the package had a few more for the price.

These threads are beautifully machined, the hex socket drive seated the Allen key with zero wobble. I’ve used a couple already for a precision fixture and the 18/8 stainless finish hasn’t shown a single burr.

I needed a long 4-1/2" bolt for a jig I was building, and these stainless steel socket caps hold tight without any rust worries. The only small issue was the threads felt a bit snug at first, but once I ran a die over them they seated perfectly.
