- What does No. 10-24 mean?
- No. 10 is the screw diameter, about 0.19 inch. The 24 is threads per inch, a coarse thread that matches standard 10-24 nuts and tapped holes.
- Can I use these in wood?
- No. Machine screws need a threaded hole or a nut. For wood, use a wood screw or a bolt with a nut and washer.
- Will they rust outdoors?
- Zinc plating handles indoor and light outdoor use. For decks, fences or anything wet and salty, use stainless steel instead.
- What head do these have?
- The listing does not name the head style. Check the product photos or package before buying if your driver must match.
- What length should I pick?
- Measure the material being joined plus the nut and washer. The 1-inch length works for thin brackets and panels; thicker stacks need a longer screw.
