مسامير زنبركية 5/64 بوصة × 1-1/8 بوصة | مشقوقة | فولاذ مطلي بالزنك (4000/عبوة)

Used these on a small assembly jig that gets a lot of vibration, and the slotted heads made installation quick. For 4000 pieces the price is hard to beat, and they all seem to be uniformly sized.

The zinc plating is holding up beautifully so far, no rust after a week of outdoor use. I used them to pin a trailer hitch coupler and they drive in tight with zero play, and having 4000 in one box means I won't need to reorder for years.

Just what I needed for a heavy-duty assembly job — the zinc plating really holds up against vibration, and having 4000 in a pack means I won't run out mid-project. Worked perfectly for aligning some stubborn brackets on a farm gate.
