براغي رأس أسطوانية #10-24 × 5-1/4 بوصة | محرك سداسي | ملولبة جزئيًا | سبائك فولاذية بأكسيد حراري أسود (100 / عبوة)

I needed longer screws for a jig I was building, and these 5-1/4" socket caps fit the bill perfectly. The hex socket drive made installation straightforward, and the black oxide finish looks clean and professional.

The partially threaded design made these perfect for my machinery fixture, and the black oxide finish looks clean against the steel. They seated firmly with a hex key, and all 100 screws had consistent threads right out of the package.

I needed these for a jig where standard-length bolts just wouldn't reach, and the 5-1/4" length was exactly right. The hex socket drive made installation straightforward, and the black oxide finish feels durable against rust.
