| 1156907 | 2010-11-27 08:18:00 | I am now assuming that this is what you are refering to and need a small driver to fit In the past I have used the square tapered tang of a file and hammered it into a piece of steel tube of the appropriate size until the tube deforms into the square shape required to fit. This method is usually only good for loosely tightened bolts Failing that as mentioned before, the 12 point socket is the way to go. Good luck |

| 1156910 | 2010-11-27 19:25:00 | OK, it's a square. That is the top is a square, not a square hole in a screw. The problem is, it's down a tube and it's small so you can't get a wrench in it, you can't even get pliers in it. Tweezers maybe but they aren't strong enough. You'd need a tiny wee square socket type thing. Anyone know where to buy such a thing? The DSE set does not have one. The nearest idea that works is what Happy Harry said. |

| 1156912 | 2010-11-27 21:14:00 | PCTEK : Number of points Modern nuts and bolt heads are made with hexagonal gripping surfaces and as such limit the number of positions a wrench can adopt when placed over them. Sockets are produced in 6-point (hexagonal) and 12-point (double-hexagonal) configurations. 12-point sockets can be used on square nuts and fasteners, and also offer double the amount of starting points, but greatly increase the chance of rounding or slipping off a nut or fastener. In general, 12-point sockets, being faster and more versatile, are used in general purpose applications, while six-point sockets are used where greater torque values are needed. 8-point sockets are still available from some manufacturers, allowing socket users to adjust square-shaped fittings rather than hexagonal ones. They were much more easily available some years ago, but square-head bolts and nuts, once common, have become a rarity in modern toolmaking. |

| 1156913 | 2010-11-28 00:28:00 | May be easier to just take it to a repair shop and ask them to do it. Which is what husband said is probably the reason for using such a thing. It's for adjusting the mixture on the chainsaw, which used to be a simple screw once, now it's recessed and this thing. It's annoying the hell out of him. And no he won't take it in, he does all his own motor repairs and maintenances. As you should be able to. We'll go with Happy harrys idea........ |

| 1156914 | 2010-11-28 00:39:00 | It would be useful to know the across flats dimension and the diameter of the access hole. It may not be necessary to make a box spanner with a square hole. The screw wont be tight. A piece of mild steel strip of thickness equal to the A/C flats size with a slot cut and filed in the end having a width equal to the square would also do. IE. it would be like an open ended spanner. The width of the strip would have to fit the access recess. It wouldn't have the strength of a tube, but it should be adequate to turn the mixture screw. Edit: Or cut a slot in the end of a piece of suitable round rod. |

| 1156915 | 2010-11-28 18:08:00 | It might even be possible to turn it with a single flat blade screwdriver rammed between the screw head and the wall of the cylinder it's in. In this case you want to encourage the screwdriver to move in an arc around the edge of the cylinder. Rough as guts, but possibly quick and cost free. Good to hear your man is on his feet again. |

| 1156916 | 2010-11-28 19:23:00 | I don't know what it is called or even if it has a name . It was utilised, originally, as a security screw - as was the philips screw - so people could not easily undo the screw . These days most people have a screwdriver that will do it . Robertson and Phillips were developed for production line use not security . Power driven screwdrivers need a bit that stays centred . Robertson "injured his hand while demonstrating a spring loaded screwdriver and after a little spare time in his workshop, applied for a patent in 1906 for a socket head screw . " The US emissions control laws are responsible for mixture screws that are plugged or need special drivers . This is an attempt to stop poor adjustment . Assuming that pctek's chainsaw is a Husky this is what the tool probably looks like . ebay . com/ADJUST-TOOL-CARB-CARBURETOR-HUSQVARNA-CHAINSAW-TRIMMER-/390025452838" target="_blank">cgi . ebay . com You won't get a socket in the hole . |
