5/8 inch bolts. Get them home Depot, stainless steel with washers both top and bottom.

I used a 1/4" diam. lag bolt into an 2x10 but hole was probably 5/16" diam. The hinge is very solid and the plastic bearing is perfect.

My husband measured the bit he will be using to drill the holes for my pulls, and he said it takes a 5/32 drill bit, or if you want the hole a little larger, use 11/64 bit size. Hope this helps!

Jim, The plate measures 8-5/8" from top to bottom and 6-15/16" wide. I didn't want to take out the bolts to measure the holes but the top holes are tapered. The bottom section of the holes on top is 3/4" which tapers up to approx. 1/2". I'm using a bolt with a 9/16" head for this. I'm using a bolt with a 3/4" head on the bottom holes. I have it mounted on a wall. This is a great unit. Get the Goodyear hoses. I had a Chinese wall unit w/ hoses before this and it was junk.

They look to be #10 straight shank approx. 2 1/2 inch long with flat head. I think larger screws or lag bolts would require you to drill out the holes a bit. hope this helps.

Standard drywall screws. I believe they were 3" in length. I also used a washer to make sure the head did not push through the hole.

I believe either 1/2" or 3/4". You should be able to find specifics on basepump.com

I am using my engine for a custom built hydraulic log splitter. There are two bolt mounting patterns. One recessed around an inset circle and fits standard hydraulic pump brackets perfectly. The other is a square bolt pattern 'on top' of the circle. Those are I believe 5.25" on center, but I can't measure at this point because the pump bracket is mounted. I believe the documentation noted their size. Based on the bracket I am using, I would guess they are a very standard size because mine worked flawlessly...

They're standard size bolts. I had to make some adjustments for my Miata, but only because I only had two holes drilled for each plate, instead of four. It didn't look right with just two. Take a look at your plate to see just how your plates attach.

Take the bolts and nuts to any ACE or True Value Hardware stores. The folks there should be able to find equivalent sizes (if not identical threading) to replace the stock hardware with longer versions. Go with stainless steel if you can find it -- the few bucks extra will be worth it once you see how quick regular steel hardware can rust (and forced to replace it over and over). Cheers and all the best, -Rob

Not sure what bolt holes or screws you are talking about, I didn't have any problems putting mine together with the instructions that came with it. Sorry I'm not any help.

Most likely, you need 1/2-13 X 3 carriage bolts (1/2-inch diameter, 13 threads per inch, 3 inches in length). Stainless steel is best.

Not sure about the hole size. I've had too many different types. Just test drill on scrap wood to make sure you have the right size bit for the threaded nut to fit in.

The screw mounts are recessed. I think the bolts I bought had a 1/4" head on them, about 1/2" length. I think the holes are 1/8" diameter. I had another mount on a platform on my bike, removed it, and put this one in without having to modify the holes. Even used the same bolts. Best advice I can give you is wait till your get yours then take it with you to the hardware store as you will have several options on bolt length and head size.

Unfortunately, there is no way to determine what type of hardware needs to be used without seeing where it will be installed; the best person to determine this would be the professional who installs it. The holes are approximately 7/16". Please let us know if we can be of further assistance!
