M20-2.5 x 40mm 육각 머리 볼트 | 클래스 8.8 강철 아연 도금 | 풀 나사산 (25개/팩)

Pulled these out of the package and the zinc coating looks even and clean, no rough edges on the threads. The hex head seated perfectly with my 19mm socket on a motor mount repair, and the 8.8 grade gives me confidence they'll hold torque without stripping.

The fully threaded body made cinching down a heavy equipment mount straightforward, and the zinc coating still looks clean after a week of workshop use. Even with a wrench torquing them firmly, the hex heads held their shape without any stripping.

Pulled these out for a job securing heavy steel brackets, and the Class 8.8 rating gave me confidence they won't strip. The hex heads fit my socket perfectly, and all 25 threads were clean with no burs.
