براغي رأس أسطوانية M3-0.5 × 4 مم | محرك سداسي | خيط كامل | ستانلس ستيل 316 (1400 / عبوة)

The hex socket drive grips the Allen key perfectly, so no more rounded-out heads on these M3s. The 316 stainless finish looks clean and should hold up well in my jigs, and the 1400-count box is a solid value for the price.

I was tired of stripping cheap hardware on my robotics jigs, so I grabbed these M3-0.5 x 4mm socket cap screws. The 316 stainless steel has held up perfectly in a humid workshop environment without a hint of rust.

Needed some corrosion-resistant fasteners for a jig that sees coolant mist every day, and these 316 stainless M3s are exactly what I was after. The fully threaded design grips nicely even in thin materials, and the hex socket drive lets me torque them down without stripping.
