There are still a few products that require the flat head screw. Dynaudio drivers used them and some terminal cups still do.
The new Dayton Audio RST28 tweeters will use these. They are a tad small but still do the job.
If you have the need, we have the product!
- #6 x 3/4″
- Flat Head Phillips
- Black Oxide
When using on plastic products, be careful not to over tighten as the screws will split the plastic.
