Our predrilled, polished stainless steel piano hinges provide uniform strength throughout the entire length of the hinge. They offer smooth pivotal action and easy, accurate alignment. Piano hinges, also known as continuous hinges, are available in 6-foot lengths only.
Piano Hinges require Flat Head or Oval Head fasteners (screws/bolts with a countersunk head). For the Stainless Steel Piano Hinges, 1-1/16" requires #4 screws; 1-1/4" and 1-1/2" requires #5-6, and 2" needs #6. 1-1/4" - 2-1/2" centers. 1 1/2" and 2" are 2" centers.

Are thses 304 or 316 SS?
304 stainless steel.
can these be painted to match the wood doors?
Yes, you will need to sand it a little to ruff up the gloss.
Is this type 316 or 304 SS?
These are 304 Stainless.
Will the hinge open to 270 degrees from the closed position?
they will open 270 degrees + or - a degree
How reliable are they?
Very reliable. I have no trouble with them whatsoever.
I used this "piano" hinge in 2 locations, and it has held up well. The downside is that the size screw that you can use is limited to a #6 because a #8 screw's head would not go into the countersunk hole deeply enough to allow the hinge to close fully. That limit is overcome somewhat by having screw holes appx every 3 inches.
what kind of stainless steel are they made from?
These are made out of grade 304 stainless steel, thanks.
Is the pin diameter .25"? My application uses truss screws with .125" head.I will grind the head down a little, so when the hinge closes the screws don't hit each other.
The actual hinge pin is .120, hinge pin housing is .258.Screw hole opening is .180, holes are recessed.
Forgot to add this: This is the HNP2S 2"X72" hinge
What is the best way to cut to length a Stainless Steel piano hinge?
you could use a hacksaw or sawzall, but I used a 4.5" angle grinder with a SS cutoff disk. This gives a very clean cut, and very quickly. BTW, and angle grinder (good one costs about $50 at a home store) and some cutoff disks will do many a task, and right quick too.
I did it with a hack saw and filed down the cut ends. If you had some heavy-duty snips, that might work too and be a little cleaner.
Buzz,I padded the jaws of a wood vice with shop towels, clamped the hinge and slowly cut it with a hack saw blade. I then used a fine file to smooth off the burrs. I works great. Good luck. Niall

How far are the holes apart ?
On the stainless steel piano hinges I bought, the holes are 2" apart. I am quite satisfied with the hinge, by the way.
how much weight can they hold?
I do not know the exact weight, it works well to replace the hatch cover that is about 10 lbs. The strength seems comparable to the brass hinges that are sold for small boxes, about 1/16th " thick metal.
it depends a great deal on what fasteners you use. I used it for the ice box lid on my boat with small screws and adhesive so in that horizontal application it's not really holding any weight. it you were to through bolt it I suppose it could hold a good deal of weight. what did you have in mind ?
If installed properly it should be able to hold 25 to 30 pounds
I used rivets not screws can walk on lids i am about 185lbs
These are stout hinges but the amount of weight they can carry really depends on how long the hinge is, how long the screws are, what material the screws are embedded in etc. If your intended application is a safety related use such as supporting a gangway to a floating dock or something similar then this is not what the intended use of a piano hinge is for. The piano hinge is best for light load applications such as hatches, companionway doors etc. If your use has any pontential to injure then do the smart thing and upgrade your specs to stouter individual hinges.
I use these in a lot of different applications, I generally try to use heavier hinges on hatches and things. I have used lighter smaller hinges for hanging locker doors and the like. Not sure of the actual load rating but I have found making sure you install all of the fasteners in solid material is a tremendous help in gettng the best service from these hinges.
I don't know the exact amount of weight they could hold...but they are very sturdy. I use them for cabinet doors made of King Starboard. I would think the limiting factor is the small screws used more than the hinges.
A lot. Could probably hold your front door to your house, if you had the 6 foot hinge version and could anchor the screws in something solid. but... the screws are small, and will be placed fairly close to the edge of any wide stock, and the metal would probably eventually fatigue if subject to prolonged heavy weight while flexing the hinge under diagonal torsion (ie mounted vertically). If horizontal and no twisting force, you'd likely be good for most anything reasonable.

Sorry I don't know. I haven't used them yet.
The wright screws I order 1/4 inch by mistake. that was the default setting. they should not even sale 1/4 inch wood screws.

Great piano hinge
Good product and fast shipping.
Out door, no rust
heavy duty looks great
Use for seat hinge on cooler. the old ones were brass and the screw heads wore right through the holes. will never happen with these. Nice counter sinks for screws and beautiful polished finish.
Great Hinges for Salt Water
I have a center console bay fishing boat. I built a teak box in which to store various items (license, wallet, watch, etc.) and affixed it to the top of the center console. There is no substitute for stainless steel on salt water. These hinges work very well and they are easy to install. Would have preferred to have shorter lengths available but I will eventualy use the remaining four feet on other projects. Good luck on the water.

Cutting hinges to length
It's been a while since I used these hinges (for a fold-out, wall-mounted framed mirror), but to cut to length, I think I used a tool I use in my model aviation building hobby. Specifically a "Tuf-Grind" cutoff wheel mounted in a Dremel rotary tool. See the link below for more info on the cutoff wheel. I then "peened" over the hinge rod to prevent it from coming loose. It has worked well so far. I suppose you could cut the hinge with a hacksaw, but the stainless material is very tough. To use the cutoff wheel, you do need a rotary tool with fairly high RPM potential for it to work well.Good luck. BobAsheville, NC[@]
Just what I needed.
I looked locally and nothing matched the quality of what I recieved from Jamestown. It was recieved quickley and in great shape. Many of the six foot hinges at local hardware stores were of thinner material and had bends and warps.
