مسامير رأس مقبس 5/16-18 × 1 بوصة | محرك مقبس سداسي | صناعة أمريكية | كامل الخيوط | ستانلس ستيل 18/8 (100/عبوة)

I’ve been using these for jig builds on the shop floor, and the 18/8 stainless finish hasn’t shown a single speck of rust after a month of coolant exposure. The fully threaded length makes alignment a breeze in tight spots.

The hex socket drive seated perfectly with my Allen wrench, and every single one of the 100 threads cut clean without a single burr. These are going into my jig fixtures and I don't expect to swap them out for years.

I needed some durable fasteners for a precision assembly, and these fully threaded 18/8 stainless steel screws did the job perfectly. The hex socket drive made installation smooth with my Allen wrench, and they feel solid in hand.
