M10-1.25 x 20mm 육각 머리 캡 나사 | 클래스 10.9 강철 일반 | 풀 스레드 (850개/팩)

The hex head design grabs my socket wrench perfectly, and every single one of these 850 screws had clean, consistent threads. They drove into the steel frame with no issues, and the 10.9 hardness gives me confidence they won't strip under heavy load.

Took a chance on the 850-count box and the threading is flawless all the way down, which made torquing them into the equipment flange a breeze. The hex heads held up perfectly under the wrench without any stripping.

Packed these 20mm M10 screws into some machinery brackets, and the hex head held a socket wrench without stripping. The 850 count will last me through several small fabrication jobs.
