M14-2 x 40mm 육각 머리 볼트 | 클래스 8.8 강철 황색 아연 도금 | 풀 나사산 (50개/팩)

These bolts cranked down evenly without any binding thanks to the clean threads and consistent plating. The yellow zinc finish on the Class 8.8 steel gives them a solid, rust-resistant look for shop use.

Perfect thread match across all fifty pieces, and the zinc coating has that clean, even shine that tells you they’ll hold up on the machine frame. My 19mm socket drove them in without a hint of stripping, and the fully threaded body made alignment a breeze on the flange joint.

The hex heads on these bolts fit my socket perfectly, no rounding even under heavy torque. That Class 8.8 yellow zinc coating seems tough enough to resist rust in my damp workshop. Exactly right for securing a metal rack frame.
