براغي ذات رأس مقبس M4-0.7 × 16 مم | محرك سداسي | خيط كامل | فئة 8.8 من سبائك الصلب مطلية بالزنك (900 / كيس)

The hex socket drive on these takes a standard Allen key with zero wobble, making assembly on my precision fixture feel very solid. Zinc plating looks uniform across all 900 pieces.

Used a full box of these on a custom jig build and every single one threaded perfectly into the tapped holes. The zinc plating on these M4 socket cap screws gave a nice consistent finish with no flaking, exactly what I needed for my precision assembly work.

The hex socket drive on these M4 screws fits my Allen wrench perfectly, no wobble at all. I used a whole bag for jig fixtures and every single one threaded cleanly without any burs or stripped heads. For the price on a 900-pack, the consistency is impressive.
