M6-1 x 8mm 內六角螺絲 | 平頭內六角驅動 | 全螺紋 | 10.9級合金鋼鍍鋅 (900個/包)

The hex socket drive grips the Allen key without any wobble, which made seating all 900 into my jig plates a lot less fiddly. The zinc plating looks uniform and hasn't chipped during handling. Good value for a full box of Class 10.9 hardware.

I needed exactly 900 of these for a production fixture, and the class 10.9 alloy steel feels much tougher than the standard stuff I've used before. The flat head hex drive sits flush perfectly in my jig plate.

Got these for a jig I’m building, and the hex socket drive seated perfectly with my Allen key—no stripping even when torqued down. The 10.9 alloy steel feels solid for the price, and the zinc plating hasn’t chipped after a few days of handling.
