براغي رأس مقبس 1/4-20 × 1-1/2 بوصة | محرك مقبس سداسي | ملولبة جزئيًا | برونز سيليكوني (100 / عبوة)

I’ve been using these silicon bronze screws for a boat cleat repair, and the hex socket drive made seating them in tight corners effortless. The partially threaded shaft gave just the right grip without bottoming out.

The partially threaded design made installation quick since I didn't have to cut the threads down for my assembly. These bronze screws feel solid and the hex socket seated perfectly with my driver.

I needed these for a jig I’m building, and the partially threaded design let me seat them perfectly without binding. The silicon bronze has a nice weight that feels solid in hand, and the hex socket drive seated easily with my Allen key.
