M24-3 X 50mm 外六角螺絲 | 10.9級鋼本色 | 全螺紋 (10個/包)

Threads were clean and the 10.9 rating on the head is easy to read, which matters when you're sorting a bin of fasteners. Drove them into a steel bracket with a socket and they seated flush without any galling. Solid value for a ten-pack.

Installing these on a press jig this week, and the Class 10.9 steel held up perfectly under full torque—no stripping or stretching. For the price, getting ten pieces of this grade is solid value.

The hex head gave my socket a solid grip without any slipping, and the threading cut into the steel plate cleanly during assembly. These bolts feel much sturdier than the grade 8.8 ones I used last time, so I’m glad I went with class 10.9 for this heavy-duty frame.
