❓ FAQs – M6 Nickel Plated Countersunk Screws
🔸 How is length measured for these countersunk screws?
For these countersunk screws, length is measured from the underside of the head (the flat bearing surface) to the tip, not including the head. For example, an M6 x 20mm screw has a 20mm threaded shank. This matches the measurement method stated in the product description.
🔸 Are these screws fully threaded? What is the thread pitch?
Yes – they are fully threaded from just under the head to the tip. The thread pitch is standard M6 coarse: 1.0mm. This ensures compatibility with standard M6 nuts and tapped holes.
🔸 Will the nickel plating rust or wear off?
Nickel plating provides good corrosion resistance for indoor and light outdoor use. It holds up well for machinery, furniture, and automotive applications. With repeated driving, the recess may show some wear, but the overall finish is durable for most general use. For constant moisture or saltwater, we recommend stainless steel.
🔸 What Phillips screwdriver size should I use for M6 screws?
Use a PH2 (size #2) Phillips screwdriver bit. This provides the best engagement and prevents stripping. A quality PH2 bit is standard for M4–M6 screws.
🔸 Can I use these screws with nuts, or are they self‑tapping?
These are standard machine screws – they require a matching M6 metric nut or a pre‑tapped hole. They are not self‑tapping. For best results, pair them with steel or stainless M6 nuts.
🔸 What lengths are available for M6?
We offer M6 lengths from 12mm to 90mm. Common increments include 12, 16, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, and 90mm. Please select your desired length from the dropdown options. If you need a length not listed, contact us.
