I know you're asking for screws, but have you ever considered using rivets
as a better alternative?

| I like these skates a lot, planning to make slight variations.

| The aluminum flat bar is 1/16" thick from McMaster. Seems springier
| than Lowe's aluminum and apparently harder so it doesn't clog my
| tools.
|
| After sanding the sides of the skate frame and the wheel fork (the two
| aluminum flat bar pieces), the pieces are coated and Super glued
| together. The wheel ends up precisely aligned.
|
| The skates are taking a beating, that's what they're for. Most of the
| forces are shearing type. Twisting pressure is handled by the
| flexibility of the frame. I have high confidence in the bond,
| otherwise I wouldn't be skating on them (away from cars and with lots
| of protective gear). At the same time, I would like to provide a
| better backup fastening than the single cheap screw currently being
| used.
|
| I would ask about screw placement, but that's probably a fine detail
| that I should determine here. The current single screw is where I
| think the bond is most likely to fail. I'll probably use more screws.
|
| Again, the aluminum flat bar is 1/16" thick.
| The skate frame thickness is somewhere between 1/16 and 1/8". I don't
| know exactly, but I think it's a pretty hard alloy of some type.
|
| Which of these McMaster machine screws would be most nearly
| acceptable?

| Is there a matching nut for a rated screw like that? How important is
| a nut on the other side of the threaded hole? I'll probably use
| superglue to secure the screw.

| Thank you.
