It states you need a 1/4 inch hole to mount these. What is the actual diameter of the bolt? I have a 1/8 inch hole to put it in.

i have a micrometer i could mic them if you really needed. I can tell you with 99.9% certainty that .125" (1/8") hole is too small and will not work. I would believe the specs. as .250" (1/4") is around the dimension I would say the bolt is. I recomend looking at another product. Hope this helped.

Hi David, The holes are 4 7/8" apart all 4 holes & 6 7/8" on the cross/diagonal. The holes are casted as part of the base plate casting. They are not drilled/machined. I state this as there may be a rough edge at the top of the holes. I used a 1/2" drill bit to deburr edge,thus using 1/2" diameter bolts to mount.

The hole takes a SAE 1/4" x 20 bolt and the Allen bolts are 3/16" SAE. I have the 48-55 MM clamps

1/2" bolts fit through the holes with enough clearance, holes are not perfect.Center to center is 1 7/16 to 1 1/2"

Mine are mounted, but eye balling the outside diameter where the chrome is, was about 4 3/8"

I would say yes. They seem to be a one fits all size. May have to take up some slack in anchor belt if to long. I did this by tying 2 knots in it just above mounting bolt......

I tried to use these with my kreg hole system and they are not a snug fit. The kreg drill bit is 1/4"

Double check your bolt pattern. I believe these are 4.25 inch 5 bolt rims. I checked them with a tape measure, but they are installed and it was hard to tell exactly, but I am certain they are under 4.5 inches on center. I hope this helps.

I purchased longer ones that were made for heavy duty leaf springs. I think there about 1/4 or 1/2 inch longer which will make it easier to re-mount the u-bolt.

The mount holes are 3/8 inch diameter. These hooks are the best I've seen ; they also come with 3/8 x 3 inch ss lag bolts.(the description doesn't say so but I ordered several sets of swing hooks and each one had lag bolts included) Hope this helps? Best of luck.

I recently used them with full 1" thick doors which worked but made the install very tight ..........7/8"should be no problem.

You need to use anchors that expand when you put them into the hole you drill. They will lock in when you bolt them down.

These were specifically made for a 7/8 inch bar diameter. That's not to say you can't make them fit but it will look wrong. It will be up to you to decide whether or not it bothers you but techincally, yes, they can be made to fit. It also may require you replacing the hardware that comes with the kit with longer hardware since the one inch diameter bar you will be mounting them to will effectively spread the clamp further apart.

They come with a 1 inch bolt. I had to purchase some #8 x 32 x 1 1/4 inch for ones where I could not countersink from behind. For the countersink I used a 3/8 inch spade bit. They are a good knob and look great.

They're actually internal mount. They slide into the bar ends. They will fit inside the end of a 7/8 inch bar and come with and adapter that will fit a 1 inch bar. You need to measure your inside diameter for these, but it sounds like you have a 1 inch bar. 7/8th and 1 inch are pretty standard on most bikes. I have 1 inch bars and with the adapter they fit good.

Hi Virginia, I am afraid you have to drill two 1/4 " holes as It calls for in the instructions.Regards,Guenter

Mounting holes are 0.9 inches X 1.3 inches. Much smaller than the ones I replaced. I had to drill new mounting holes to use.
