براغي رأس سداسية M6-1 × 40 مم | محرك سداسي | ملولبة بالكامل | ستانلس ستيل 316 (200 / عبوة)

Used these to secure some marine fittings, and the 316 stainless held up perfectly against the salt spray during testing. The hex socket drive made installation quick and easy with no stripped heads. Exactly the quality I needed for a long-term build.

Having just rebuilt a precision jig, I can confirm these 316 stainless screws threaded perfectly into existing tapped holes without any binding. The fully threaded shaft gave me exactly the grip length I needed for a secure assembly.

The hex socket drive on these M6-1 x 40mm screws grabbed my Allen wrench perfectly without any slipping, and the 316 stainless steel feels sturdy for the jig I built. The fully threaded body made adjusting the fit in my machinery setup a breeze. I'm glad I went with a 200-pack for future projects.
