Do any of you know if you can somehow convert an Allen bolt with some sort of cap you can put on the head so you can use your fingers instead of requiring an Allen key? Have been scouring the web but either I'm lame at searching online or it's a product I fabricated in my mind.

Some bolts are also suitable to be replaced by kip handles

I used to have a box of 100 + / - of the Press Fit knobs. They are available in all manner of size/ shape. A few cautionary notes:

When pressing them in, you will need a mallet not a hammer. They should be resting knob facing up and socket head resting down against the center circular spud molded into the knob. Using a flat wooden surface instead of a metal one does reduce the potential for shattering the knob.

You'll waste one or two fine-tuning your strike force so you can accomplish the real goal: A very centered vertically mounted bolt with knob. It is possible due to the design of the press-fit knobs to press it into place using a mallet and have it not be dead vertical. This could be annoying, or it could be a dealbreaker.

Shattering a knob or having a bolt be seated not vertical is a small loss for the knob. One must take some serious effort, however, to remove the plastic spud that has been pressed into the hexagonal Allen Wrench hole at the top of the socket head cap screw. I used to use a small Dremel boring bit to crack the pieces out without damaging the integrity of the socket head hold.

My two cents.

Best to all,

Peter Abraham, S.O.C.

Or you could do it the proper way with either a Bench Vise or a C-Clamp and actually PRESS fit them

Striking them with a hammer or mallet is both ill advised and silly when you can do it correctly so easily with a c-clamp or bench vise
