1/4 Inch Hex Knob (3/16th's Hex)

This knob allows you to open a 1/4" socket head bolt with just your fingers. No key or wrench needed. You can use it as a tool or permanently mount it to your bolt with some CA glue. No more searching for that specifc 3/16's allen or hex key. My incra miter sled had a dozen ¼ inch bolts and now I can use it completely tool-less. Happy Printing.
