HOLO-KROME 72294 براغي غطاء مقبس 5/8-11 × 6 بوصة | محرك مقبس سداسي | سبيكة فولاذ معالجة حرارياً أسود (10/عبوة)

I was a bit skeptical ordering fasteners online, but these 5/8-11 x 6" screws threaded in perfectly on my jig build. The hex socket drive made installation quick with an Allen wrench.

The black oxide finish on these screws held up perfectly when I used them to secure the tooling on a heavy-duty press. Thread engagement was smooth right out of the box, and the hex drive seated without any rounding.

These bolts handled the jig I built without a hint of flex. The socket drive seated perfectly with my hex wrench, and the 6-inch length gave me just the right reach through the steel plate.
