M5 X 16mm 平頭內六角止付螺絲 | 18/8 不鏽鋼 (500 / 包)

Put these into my CNC fixture’s adjustment screws, and the hex socket drive made torquing them down in a cramped spot a breeze. The 18/8 stainless feels solid and should resist corrosion well. Exactly what I needed for a precise fit.

Finally, flat point screws that don't strip when I'm driving them into aluminum angle. The hex socket holds the bit perfectly even in tight spots. Worth every penny for the stainless steel quality.

Used a full bag of these on a jig and not one stripped head, even with my impact driver on a low setting. The 18/8 stainless held up fine outdoors, and the flat point seated squarely every time.
