Been goin thru some of my Dad's tools and found a few wrenches in 32nds. Is there anything built anymore using that demention? Has there been for yrs & yrs? Only use I remember them for is when another bolt has been "rounded" some they will work. Any idea's?
Could the 11/32 wrench be part of an ignition wrench set ? I have a set like that which has many various x/32 wrenches .
No idea. There are open/box, open/open of different size & box/box of different size. Different makes too. I have boxes & boxes of wrenches/tools. Dad had his,his Dads,Mom's Dad's, and Mom's step Dad's. Many over 100 yrs old I'm sure. Even got a Model T thread chaser in there somewhere. My favorite is the "one drop oil can". About the size of a cigarette. Unscrews & has 2" wand. My guess is it was for sewing machines or fishing reels, but what do I know? Thanks for the reply.
I've heard some tell of "Whitworth" (sp?) wrenches for some vehicles that were said to be fractional in increments between the 1/16".They were said to be for UK built vehicles (can anyone else confirm this?). I've used 11/32" for nuts on numbered size bolts possibly #8.If you have larger wrenches maybe "Whitworth"?
9/32 and 11/32 fit ignitions on alot of vehicles, i have an ignition wrench set that has those sizes, and usually very thin little wrenches too..
Yes Whitworth wrenches were for British cars. The 11/32" wrenches were not Whitworth. Some larger size strange measurement wrenches were used on antique Chrysler products. I never get rid of any size wrenches because you never know when you will need them. There is a British brand wrench called "King ****" which I am sure a lot of people on The Hamb can make comments on.
Yep,correct.I still have a few Whitworth wrenches.They were phased out,I think,in the '50's early '60's and replaced with UNC and UNF(Unified fine and course) threaded fasteners to be compatible with AF and AC,using the same wrench sizes.
In most cases those sizes date back to prior to WW II-before Unified Thread Series design and before the S.A.E. standardized screw head sizes by screw diameter.
Triumphs ran whitworth off and on up into the 70's, even going so far as having some bikes have standard and whitworth parts. real pain in the *** metric or standard doesn't properly work on whitworth heads and the thread pitches are even different. first few triumphs were a real treat until i got a decent set of whitworth wrenches and sockets and now have a british hardware drawer
On 228-302 GMC's and 216-261 Chevy's ,there's a pointy bolt with a lock nut to secure the oil pump.I have found on some that the nut is actually 19/32's.Usually guys pound on a 5/8 or ****** up the nut with an 11/16.
I've wondered about this also I have a 19/32 socket never seem to have a use for it. If i remember corectly it fit some body mount bolts on a 80's Chevy, but the may have been metric. The question I have in countries that use metric do they still use 3/8" and 1/2" drives for their sockets or are they metric also? And do they make true metric drill bits? All the metric sets I see look more like there just relabled standard bits - 4.325mm,6.21mm ect. not trying to get OT Just curious.
You forgot very early seventies Trumpets with Whitworth, SAE AND Metric!!! Talk about a pain in the ***...
BSW (British Standard Whitworth) wrenches are in the toolbox of every A&P that works on British-built aircraft. DD
I have a couple of old combo box ends with 25/32 and 29/32. Never have needed to use them though...I wonder if those sizes were used by a certain trade? (not auto)
Everything I've seen in European tools use the same drive sizes for sockets as US tools use. Drills are made in a full range of true metric sizes. In addition to the full number sizes, they are made in 1/10 mm increments and some smaller ones are made in .05mm increments. Some of the common non-integral sizes common in the US would be ones for use as tap drills for tapped holes. The tap drill for a metric thread is sized by taking the nominal thread diameter and subtracting one thread pitch. For example, a M5 screw has a 0.8 mm pitch, so the tap drill is 5 - 0.8 = 4.2 mm. Very easy way to figure out the proper drill size if you need to drill and tap a metric hole. FWIW, the same thing works on USS and SAE threads. Taking a simple one, 3/8-16 for example. 16 threads per inch, so the thread pitch is 1/16". Tap drill size is 3/8 - 1/16 = 5/16" Good to remember if you don't have a tap drill chart handy. Another item where inch sizes are used worldwide is wheels. In Europe or Japan or wherever, 14", 15", etc wheel sizes are used the same as here in the US.
I have many 3 /32 wrenches I have used for lots of things I have found that take them. i have 7, 9, and 11/32 in my kit. Also, forgive me if I am wrong, but I believe the Brit sockets are called Wentworth. I have a set of those I used when I rebuilt the 1969 BSA 650 I bought from my brother way, WAY back.
I still have some 21/32 &23/32 plus a 29/32 sockets and end wrenches and crow foot type tools that I came into possession of while in the air force about 50 years ago...These were used on jet engines and aircraft.. All my friends always ask what the F&%# when they pick up these size tools... Bobby..
A good comparison chart of US, Metric, and Whitworth wrenches with decimal inch dimentions can be found at http://www.semgtr.org/resources/Wrench_Size.pdf. Whitworth thread, bolt, nut, and wrench sizing gets real interesting real fast. Googling "Whitworth wrench sizing" will bring up a number of sites with a lot of detailed history and information that will clear up many common misconceptions about what the British used over the years.

i use 11/32" wwrenches on 10ghz.waveguide flanges on microwave antennas on communications towers. i find them at pawn shops.
As stated before the smaller sizes 32nd wrenches are mostly for ignition use.My first set of tools(received at 16) included a couple of Snap-On 3/8ths drive sockets in 17/32nds and 19/32nds.I was told that the 19/32nds was for use on certain GM exhaust manifold bolts.Never have had occasion to use them. Awhile back I purchased some really old(1920's-1930's era)tools mainly because I wanted the box and in it were some really strange stuff including a 1/2" drive set of 4 point sockets(3/8ths to 7/8ths);two hex drive sets(different sizes)and a set of 1/2" square drive sockets from 3/8ths to 1-1/4" including a 25/32nds and 31/32nds socket.
I bought a very old socket set at an auction once without looking at it too close and it turned out to be 7/16 drive.
The 17/32, 19/32, 21/32, ect. wrenches were for Weatherhead fittings. The fittings are still made in those sizes, but most people think they are metric. The reason for this was Metric wrenchs would work, so they could sell the same fittings everwhere. I have a old set of Weatherhead branded sockets I inherited from my grandfather.
