Solid brass for durability, made to order in small batches. A few on hand and several more in the queue.
These nest securely into the pierce cup inner diameter, so there's no risk of slipping out. The hex on the back will fit a standard 1/4" screwdriver extension or nut driver.
$22 shipped in the US, or buy them on my website.
