- What is a machine screw used for?
- Machine screws join metal parts or hardware using a nut or a threaded hole. They are not for driving into wood without a nut or insert.
- Do these work outdoors?
- Zinc-plated steel handles indoor use but will rust outdoors or in damp spots. Use stainless steel for exterior work.
- What driver do I need?
- A standard Phillips screwdriver. Match the tip size to the screw head to avoid stripping it.
- Will the flat head sit flush?
- Yes, if the hole is countersunk. In a plain hole the head will sit on top of the surface.
- How do I know the size?
- The pack label lists the diameter and length. Check it against the old screw or the hole before buying.
