1/4-20 X 6" 內六角螺絲 | 圓頭內六角驅動 | 全牙 | 18/8 不鏽鋼 (50個/包)

Needed exactly 50 of these for a tooling jig, and the bag had every one accounted for with threads that were clean and burr-free. The hex socket drive seated my Allen key perfectly, no wobble at all. These feel solid in the hand, just what you want from stainless.

Every single one of the fifty came out of the box with clean, uniform threads and a smooth hex socket, which made my jig assembly a breeze. I've been using them for a week now and they hold up better under torque than the cheaper black-oxide ones I had before.

Used a few of these to mount a jig in my shop, and the fully threaded 6" length gave me exactly the grip I needed. The 18/8 stainless feels solid and the hex drive seated perfectly without stripping.
