Image Wrench.JPG moved to Monkey wrench. I'll move it back and accomodate it here if you think it needs it. Drover 20:41, 9 Aug 2004 (UTC)
Image was moved to Pipe Wrench, not Monkey wrench. — Drover 00:06, 10 Aug 2004 (UTC)

[edit] Any chance of "spanner" in the subject title?
"Spanner" redirects to "wrench", which is fine, but it's not the normal UK word for the tool. Any chance of the word "spanner" being put alongside "wrench" in the title, so as to not put undue emphasis on the American terminology?
- Fair question. I suggest that some mention is made of the different names for the 'Allen Wrench'. Specifically to point out that in the UK it is commonly known as an Allen key, given the fact that it is not used for gripping the outer diameter of something like a normal wrench does.
I don't see any way to change the main title (as the page was started in the USA and so named 'wrench' and redicted from 'spanner'), but I have added 'spanner' to the sub-headings. --Pcrawford 15:16, 1 February 2007 (UTC)
The page wasn't displaying correctly in Firefox 1.02 or Mozilla 1.7.6. The Contents box was either hiding beneath an image, or when it was closed, the page redraw was causing problems with the other images.
I've moved the adjustable spanner down to it's description and rejigged a heading.
Opera , FF and Mozilla are displaying it acceptably, hopefully IE will too. -- Graibeard 11:47, 24 Mar 2005 (UTC)
[edit] Nummular spanner
Please could someone knowledgeable add some info about a nummular spanner?
'Nummular' was the correct answer to a crossword clue "Type of spanner" but this spanner is not mentioned or described in Wikipedia, and a search on 'nummular' does not bring up anything relating to a spanner or wrench.
Many thanks!
[edit] Disambiguation
I think WRENCH needs a disambiguation page, there are actually quite a few ambiguities. Whoever's the wiki expert paying attention here, thanks in advance!
[edit] "Flat" to mean "open ended"?
Recent edits:
- "Combination wrench, or combination spanner" replaced by "combination Flat and Ring spanner",
- "Double open-end wrench or open-ended spanner" replaced by "double Flat spanner",
- "Open-end wrench, or Open-ended spanner" replaced by "Open-end wrench, or Flat spanner"
It seems that for the person who made these edits "flat spanner" means "open-ended wrench/spanner" (is this S. Afican English?). However, existing standard terms should not be removed, also there maybe confusion with "flat" to mean the general shape of the whole tool. LDHan 12:45, 26 December 2006 (UTC)
Certainly you can get both 'flat' ring spanners (where the ring end is in the same plane as the handle) and 'offset' ring spanners (the more common type where the handle is, as the name suggests, offset from the nut-turning ring part). For example, this web site http://www.deltec.net/impact.htm is offering "a complete range of Slogging Spanners in Flat and Offset Ringed". Which also reminds me, no mention of Slogging Spanner yet... --Pcrawford 20:26, 30 December 2006 (UTC)
[edit] Face Driving sockets
I removed this statement:
"In addition, face driving sockets are available. These are more durable still, and have the ability to drive a range of hexagonal head sizes, with less risk of damaging the nut or bolt head than traditional "corner" drivers."
As I have some serious doubts about its accuracy. Here are my concerns:
(1) If such sockets do not drive the corners, can they drive a round bar? No, as what they are talking about is trying to move the nominal drive point around on the corner (i.e. hex protrusion). Still driving the 'corner' then!
(2) There are numerous companies all claiming to have a better shape for a socket to drive a hex nut/bolt head, but has anyone yet demonstrated that the shape is more important than the free play?
(3) So far, I have never rounded off a nut/bolt due to using the correct size of socket or spanner. Normally the bolt/stud shank shears due to excessive torque first. Where I have managed to round a nut it has been due to using an adjustable spanner (where the jaws tend to open at high torque, even with a good quality one) or open ended spanner with poor access (i.e. not perpendicular to the bolt axis and/or not fully engaged).
(4) The "ability to drive a range of hexagonal head sizes" is asking for trouble. Again, quality of fit is important, and what we are talking about here is attempting to save money with a socket that is not quite right for some sizes, but pretending it is 'good enough'. Most cases of damage are due to using the wrong size spanner/socket, typically due to having only one standard of tool (e.g. AF or Metric) and using it on another standard's head size (e.g. Metric, AF, Whitworth or BA).
Having said this, I have used a socket that had the tips of the corner opened out, but the reason for this was to allow a good tight fit on the main 'flat' section without having problems of fitting the socket on if the tips of the nut have already been damaged. Again, the key factor here is a good fit.
Has anyone any comments or facts (e.g. test results, stress analysis, etc) about this? --Pcrawford 11:11, 9 January 2007 (UTC)
- I think the quote might be confusing two things: the "one tool fits all sizes" type of spanner (not adjustible spanner), and normal sockets made for one size of nut of bolt which drive the flats instead of the corners. LDHan 14:52, 9 January 2007 (UTC)
I think the original author was refering to the 'metrinch' (and similar) claims for both spanners and sockets such as: 'For example, with a spanner 19 mm it is possible not only to tighten or undo a metric nut or bolt, but also the inch bolts 3/4" AF, 3/8" BSW and 7/16" BSF'. This example is allowing for 1.02mm of difference in nut size and it is something I am sceptical of working well. This is why I wondered if anyone had actual facts to back up the marketing claims and vauge technical assertions that come with a lot of these tools. --Pcrawford 15:42, 9 January 2007 (UTC)

just curious... what kind of material or metal is commonly used in making wrenches, vise grips, etc.? (ex. AISI C1020 Annealed, etc.) —The preceding unsigned comment was added by 203.76.193.246 (talk) 17:21, 16 March 2007 (UTC).
