مسامير عربة 1/4-20 × 4-1/2" | ملولبة بالكامل | فولاذ عادي A307 درجة A (150 / عبوة)

The square neck on these grabbed into the wood instantly, so I didn't have to fight a spinning bolt while tightening them from the other side. For 150 pieces at this price, the fully threaded shaft makes them a solid deal.

The full 4-1/2" length is perfect for the thick timber brackets I'm working on, and the plain steel finish feels solidly machined. Threads ran smooth all the way down with a wrench. Exactly what I hoped for at this price per piece.

The square neck under the head really locked into the wood, preventing any spinning. For a 150-pack of fully threaded 1/4-20 steel bolts, the value is solid. A307 grade feels sturdy enough for my outdoor bench repairs.
