- What does No. 8-32 mean?
- No. 8 is the screw diameter (about 0.164 inch) and 32 is the number of threads per inch. It threads into a matching 8-32 nut or tapped hole.
- Can I use these in wood?
- Not well. Machine screws need a threaded metal hole or a nut. For wood, use wood screws instead.
- Are they good outdoors?
- Only short term. The zinc plating slows rust but will not hold up to rain or salt. Choose stainless steel for outdoor use.
- What head and drive do they have?
- A flat (countersunk) head with a Phillips drive. The head sits flush in a countersunk hole.
- Do they come with nuts or washers?
- No. The box contains the screws only, so buy 8-32 nuts and washers separately if you need them.
