- What does 8-32 mean on these screws?
- It is a No. 8 diameter with 32 threads per inch, a common fine machine thread. It fits nuts, threaded inserts and tapped holes of the same size, not plain wood.
- What is a combination truss head?
- The head is wide and low with a drive slot that takes both a Phillips and a flathead screwdriver. The wide head spreads clamping force over more surface.
- Can I use these outdoors?
- Only briefly. The zinc plating resists indoor moisture but will rust with prolonged rain or damp, so stainless steel is the better choice outside.
- Do these come with nuts or washers?
- No. The pack contains the screws only, so buy 8-32 nuts or washers separately if your project needs them.
- Will the truss head fit a countersunk hole?
- No. A truss head sits on top of the surface rather than sinking in, so it needs a flat or slightly recessed area, not a countersink.
- Are these the same as wood screws?
- No. They have a machine thread for metal nuts and tapped holes. In wood they need a threaded insert or a nut on the back.
