Questions about this product
- What lengths and diameter do these screws come in?
- These are M4 screws available from 70mm up to 200mm long. The long range suits deep-set jobs in thick wood or behind switch boxes. Head diameter is about 8mm, typical for an M4 countersunk head.
- Do I need to drill pilot holes first?
- No, the self-tapping point cuts its own thread in wood and soft materials. That speeds up installation and means fewer tools on hand. For very hard or thick stock, a small pilot hole still helps prevent splitting.
- Will these screws rust outdoors?
- They're 304 stainless steel, so they resist rust and atmospheric corrosion well. That makes them fine for indoor work and general outdoor use. The countersunk flat head sits flush for a clean finish.
