#8 zinc plated wafer head screws are ideal for attaching wicks to your props. These are the same screws we use for our staffs and many other props. The flat head holds the wick securely and sinks below the wick, so you do not have any protruding hardware, reducing potential injury from burns or scratches.
The self-drilling points drill through aluminum and steel when screwed in, so you do not have to predrill the holes in the prop.
1" screws are appropriate for most staffs and larger props. We use the smaller 3/4" screws for small props like fire wands or small torches.
