kmc0929 Posted February 27, 2010 Posted February 27, 2010 I chewed the **** out of the nut that holds the front sight blade on there when replacing it. I think I was using a 5mm or 5.5mm ignition wrench. Is there anywhere I can find a better wrench and a replacement nut? Quote

StrangerDanger Posted February 27, 2010 Posted February 27, 2010 5.5mm wrench, open ended one. There is no room for a socket. The Brownells link is a good place to buy the 10 dollar nut. I recommend you buy some other things to make the shipping charge hurt less. The nut is about 6.60 if you have a LEO account setup. Highly recommended. I had similar issues with my wrench. I put a drop of blue locktite on it to make up for any lack of torque that I couldn't get on the nut without rounding it. It along with the nylock washer in it should hold it in place. A 1000+ rounds later, and it hasn't shaken loose yet. Quote
kmc0929 Posted February 27, 2010 Author Posted February 27, 2010 Thanks, now here is the hard part I have to take the rounded one off, not to mention i put a dab of red loctite on there... i know.... i guess i will just heat it up and try to use that same 5.5 ignition wrench again. ANY ideas on a better wrench? Quote
Hookster Posted February 27, 2010 Posted February 27, 2010 Hi KMC, The 5.5mm seems to be the closest fit (standard or metric) although it still seems like a slightly loose fit. If it's too rounded to get off after heating it up you might need to get creative with a dremel Later, Hookster Quote
kmc0929 Posted February 27, 2010 Author Posted February 27, 2010 Anyone seen a different wrench other than the set at sears? the sears set is so thin i think that helps it round off the nut. a thicker wrench would be better. Quote

Snap on tools google them get the local mans number take your barrell to his truck and tadawwww Quote
Hookster Posted February 27, 2010 Posted February 27, 2010 I bought this one, I believe it's made in Germany, it is a bit beefier than the Sears wrench and I didn't have to buy the whole set http://www.amazon.com/Wiha-35002-Wrench-5-0mm-5-5mm/dp/B000IBOOBM later, Hookster Quote
heckler&kochp2000 Posted February 27, 2010 Posted February 27, 2010 (edited) I believe it's made in the U.S.A http://buy1.snapon.com/catalog/item.asp?P65=&tool=all&item_ID=4739&group_ID=529&store=&dir=catalog http://buy1.snapon.com/catalog/item.asp?P65=&tool=all&item_ID=4738&group_ID=529&store=&dir=catalog Edited February 27, 2010 by heckler&kochp2000 Quote
texas skeeter Posted February 27, 2010 Posted February 27, 2010 now here is the hard part I have to take the rounded one off you do know that your m4 IS NOT a MAC Truck!!;)ya cant keep wrenchin on a small little dainty nut!! just sayin..... Quote
StrangerDanger Posted February 27, 2010 Posted February 27, 2010 I think due to the design of the nut, a better quality wrench won't help much. It almost seems as if it has a slight taper on it. I considered grinding the round wrench down at the front so I could pass it below the nut. I figured I would do that if I couldn't get the nut tight enough with the open ended wrench. Once I began to feel the wrench start to strip past the high spots, I stopped. Bumps, hits and a 1000+ rounds later, it hasn't budged. If your sight is secure but just chewed up, I'd consider leaving it alone. Quote
kmc0929 Posted March 4, 2010 Author Posted March 4, 2010 benelli usa just told me on the phone it was a 3mm wrench... Quote
texas skeeter Posted March 4, 2010 Posted March 4, 2010 benelli usa just told me on the phone it was a 3mm wrench... well unless italy has different sizes in mm's than every other country, the person that told you that is WRONG!!!! i tried the 5mm= no good and the 6mm= no good. the 5.5mm worked, a little loose which was good as to not scratch the sh-t out of the nut while positioning for the next turn. and im pretty sure all mm's are a universal same size.

OhioM4 Posted March 4, 2010 Posted March 4, 2010 (edited) Has anyone tried a 7/32" English wrench? It's only about .003" different from 5.5mm and that may make a difference. Different manufacturers may have different tolerances for the opening. I think someone mentioned Snap-On earlier in this thread. I have used their tools to remove nuts, bolts, and screws that were mangled by cheap tools. Don't be fooled by the Europeans. I was in France and checked out a hardware store. The most common pipe fittings were 12.5mm (we call it 1/2"). There were a lot of bastardized mechanical things that are actually sized by the old English standard but given metric equivalents. I have not checked recently but my Jap cars still had English lug nuts and battery cable bolts. Edited March 4, 2010 by OhioM4 Quote
kmc0929 Posted March 5, 2010 Author Posted March 5, 2010 i just wish there was a clear answer to this. i have the new nut tightened on there but its not very tight. i want to tighten it down but 5.5 is going to round it off. what is the actual size, i wish i had some calipers. Quote
