As Dave noted they are specialty fasteners made specifically to join and tap into plastic parts. The tell tale sign is they have a flat tip, not pointed or material cutting.

I am for enjoying the battle, so not having 8:1 ratio with mucho BBs isn't a deal breaker for me

Still fishing the old Penn 49's on stripers and blues, some prewar, updated carbon drags, big diameter body 3 1/2 ratio, and cheap and plentiful to buy.
For trolling they mostly live in the rod holders. I'd put in a 5 disk drag if it were available, but the 3's in carbon have been fine.
The new top shelf stuff is fine, but I can buy one Avet or a dozen or 2 of the 49's for the same cake.  Difference in landed fish for me. Zero.

Truss or pan head self tapping

Bought them in 50# cartons of 304 or 316 stainless in both 1 and 1 1/4" lengths depending on the contract.

What's your application?

In reels I find them in the Chinese cheapo's, quick production, lifespan not so much.

The Penn Fathom LPs are coming out of the same design and factory of Abu Garcia LP reels in Korea. Definitely a welcomed addition to the Penn lineup having some great LPs with solid design.

Get a 5 ft. taylor's soft tape.  They're really inexpensive too.

One more note:  I am not sure if there is a standard for thread geometry and pitch for thread forming screws like these.  If so, best to use the original thread screw or official replacement part if possible.

1. Sheet metal screws have a tighter thread pitch, a different thread geometry, and a pointed tip.  Sheet metal screws are technically thread rolling screws,  as rolling (using the sheet metal working term) is how the thread is shaped in the sheet metal hole.

2. Thread forming screws squeeze the plastic around the screw thread to form the female threads, forming the plastic into the thread shape in 3D, without any cutting to remove  material, and minimizing any surface deformation.

3. "Self-tapping" is a generic term for any type of screw that does not require a hole  with female threads.

I am nitpicking here because this is important for work on reels with plastic parts. When you are putting screws into plastic holes without threaded inserts, the only proper screw type is a thread forming screw.
