Excellent product. Could be a tutorial on how to use these double-threaded reversed screws as some vintage baffles use grill-cloth-head-facing single thread screws in the baffle to hold the speakers. Best way to utilize is to use a drill motor and gently strip out the wood (careful, it's particle board) with the original single head screw and then insert the Original Fender Vintage Speaker Mounting Stud, pushing all the way up to the larger reverse screw threads at the top and then screw in the rest of the way in a counter-clockwise motion til flush. This way the longer threads are not pushing back while you are trying to seat the stud. This method worked great for me. Any questions?

Working on a beat-up '67 Pro Reverb and wanted to replace the overly-long non-original speaker screws. Baffle is original, and the holes are sufficiently tight for a normal 8-32 screw to thread in the hole tightly. When this screw's reverse threads started entering the board, they pushed the particle board OUT, delaminating it! Because the 8-32 threads and the reverse threads are going in opposite directions, they spread the board apart. I backed the screw out and assessed the damaged hole. It now has wood puffed out around the hole and flaking off.

To work correctly, this screw would need a clearance hole for the 8-32 threads. I could have used them if I had enlarged the holes in my baffle slightly so the 8-32 threads wouldn't grab. I decided to just use regular 8-32 x 1-1/2" flat-head screws instead.

These are good screws for the right application, but don't expect them to pop right into your BF or SF Fender.

I am working on a stock '66 Princeton Reverb at the moment, and it has regular 8-32 x 1-1/4" flat head Phillips black oxide screws for the speaker. The writeup for this screw suggests that they were original equipment in these amps, and that's not correct.

They are good screws but the misleading description means 3 stars.
