براغي ذات قبعة مقبس 1/2-13 × 1-1/8 بوصة | محرك مقبس سداسي | ملولبة بالكامل | فولاذ سبائكي معالجة حرارياً بأكسيد أسود (50/عبوة)

Went through a full bag mounting jig plates and every single one threaded clean without a single bad dog point. The alloy steel and thermal black oxide give them a nice uniform look, and the hex socket drive grips the Allen key snugly. Exactly the right length for my fixtures.

The black oxide finish on these screws looks clean and should resist rust well in my shop environment. The hex socket drive made installation straightforward with no stripping.

I needed a batch of heavy-duty fasteners for a jig I’m building, and these 1/2-13 x 1-1/8" socket cap screws fit perfectly. The hex socket drive grabs the wrench securely, and the black oxide finish seems tough and residue-free. Pack of 50 is a nice bonus for the price.
