مسامير عربة 3/8-16 × 9-1/2" | فولاذ مطلي بالزنك درجة A307 A (50/عبوة)

The square neck grabbed the wood perfectly on my fence repairs, so no spinning once I got them seated. Nine and a half inches gave me plenty of bite for sandwiching two thick boards together. These should hold up well with that zinc coating.

The zinc plating looks even and hasn't shown a speck of rust after sitting in a damp shed for two weeks, and that rounded head sits flush against the wood like it was meant to be there. These 9-1/2" lengths gave me plenty of bite for sandwiching two 4x4s without any wobble.

I needed longer carriage bolts for a heavy timber frame, and the 9-1/2 inch length was spot on. The square neck grabbed perfectly, keeping them from spinning as I tightened the nuts.
