Fine-Thread Metric 316 Stainless Steel Button Head Hex Drive Screws
Closely spaced threads on these screws fit in holes with a fine pitch. They're not compatible with standard metric threads. Made from 316 stainless steel, they are more corrosion resistant to chemicals and salt water than 18-8 stainless steel screws. Screws may be mildly magnetic. Length is measured from under the head.
