براغي رأس أسطوانية 1/4-20 × 2-1/4 بوصة | محرك سداسي رأس زر | فولاذ سبائكي (200 / عبوة)

The 1/4-20 threads cut cleanly into my jig fixtures without any binding, and the hex socket drive grabs firmly with my Allen key. All 200 came in a sturdy box, no bent threads or missing pieces—exactly what I needed for a batch of precision assemblies.

The button head sits nice and low on my jig, and the alloy steel feels solid when I torque them down with a hex key. Bought the 200-pack for a batch of fixtures and every single one threaded clean without any burrs—that alone saves me a headache.

I needed some heavy-duty fasteners for a jig I was building, and these 1/4-20 x 2-1/4" alloy steel button heads fit the bill perfectly. The hex socket drive made installation smooth, and the 200-pack gives me plenty of spares.
