1/4\" x 4\" 彈簧銷 | 開槽 | 鋼鍍鋅 (1000個/包)

Slipped these into a heavy machinery guard mount earlier today, and they drove in evenly with no binding across all 1000 pieces. The zinc coating looks consistent and should hold up fine against shop moisture.

Had to secure some shed shelving brackets under constant vibration, and these pins held solid without any shift. The zinc plating seems decent—no rust after a few days in a damp garage. Exactly what I needed for the job.

Used a handful of these to secure a bracket on a heavy-duty trailer ramp, and they drove in cleanly without galling. The shear strength is noticeably solid, and the zinc plating holds up well even in damp conditions. Exactly what I needed for the job.
