Tall Turret Lugs for .125 inch board above

Plated Turret Lugs for the 1/8th (.125) inch thick circuit board material I sell on this page
These lugs fit my Pre-drilled Hoffman style boards.
Turret lugs are more expensive than an eyelet because they are a solid piece of brass that is turned on a lathe type machine
Once the desired shape is there, the lugs are then sent to a plating company and plated with a very nice coating so that they can be soldered to.
Turret lug construction is much nicer than eyelet construction, IMO.
I have my turret lugs custom made for in batches of 100,000, these are not off the shelf lugs.
Use the 3/32" drill on the Tools page to drill the holes in your circuit board and install the turret lugs.
Use the lug and eyelet installation tool on the Tools page to install the lugs.
Go to this page to see how turret lugs are installed in a circuit board and how parts are mounted.
Order a couple more lugs than you need in case you damage one or the counting scale I use is off by a count of one

Tall eyelets for .125 inch board above

Tall eyelets for the 1/8" thick circuit board on this page.
You can use the pointy end of the turret lug tool I sell to flair out your eyelets.

Note on installation: The eyelet goes into a hole on the board.
It sticks out past the back side of the board just a little.
You then swage or flair out the backside of the eyelet so that it stays on the board.
The lug and eyelet installation tool can be found on the Tools page.
