loctite 601

Postby Ian Austin » Sat Mar 09, 2013 11:31 am

Am constructing a High Levels gearbox and have reached the stage where I need to put the worm onto the motor shaft. As its too tight it needs to be eased slightly. The Instructions say to use Loctite 601 to fix. Where can one buy Loctite 601 (10ml size)? I Have trawled the internet without success and have onlyf ound it in quantities (50ml or more) that would last a lifetime. Superglue has been suggested to me as an alternative.

Ian, 10ml will last a modellers life time.... Look in the big hardware chains, here in Australia, we can pick up a small range of loctite products which I think included thread loc... which could do the job also!

Loctite 601 I thought was obsolete, look for Loctite 603.

601 is still available at RS and Amazon, google it!

I've had the same bottle of 601 for about 12 years now. Still as effective now as it was back then!
That would be an ecumenical matter.

This "longevity" of Loctite has been discussed before.

It does have a shelf life. Newer bottles even have a "use by" date. I eventually had to replace my umpteen years old 601 when it stopped working.

Googling, I found Loctite's own listing of products: http://www.loctite.co.uk/cps/rde/xchg/henkel_uke/hs.xsl/fullproduct-list-loctite-4995.htm?countryCode=uke&BU=industrial&parentredDotUID=productfinder&redDotUID=productfinder&param2=mode%3Dfull%7C. The shaft-retainer potions are all in the 600 series.

603 and 601 are both on this list, so presumably both in production, and seem to have different specs: 603 is quoted as oil tolerant and 601 not.

Note the different gap-filling specs: 0.1mm up to 0.5mm.

The site also has full data sheets for products: http://www.loctite.co.uk/cps/rde/xchg/henkel_uke/hs.xsl/technical-data-sheets-5361.htm

Many thanks to all respondents. I thought Loctite 603 was for using when you might have to consider removing the item wheras 601 I understood was permanent. I do have some 603 and I will obtain some 601 from one of the various sources suggested. Thank you all once again. What an excellent helpful I Society belong to. Cheers.

They'll both let go if you get them hot - above 1500C. Major difference is that 603 is more tolerant of contamination (oil) on the joint.

Hi Will
Thanks. Hadn't realised 603 had similiar qualities, oil tolerance apart.

I think Branchlines might stock it. They attend Epsom, EM, P4 shows and probably others. Not much of a web presence though.
Make Worcestershire great again.

I got some Loctite 603 a year or so back, in a 10ml bottle complete with dropper, from Reeves model engineering suppliers at Austrey, near Tamworth - http://shop.ajreeves.com/contact-us-2-w.asp. Can't remember what the cost was but as it'll probably outlast me.... :(

£10.80, according to Reeves' website.

Umm I was wondering around the newest Hardware warehouse here in Melbourne (the new Masters for those closer to home) they have a thread locker which is removable and then there is a permenant version. This is not locktite but another version. I was thinking to myself that the permanent version might do if my 601 has lost it's stick! Of course all in the "glue" isle and at only about $4 for a couple of ml it doesn't sound so bad.

Branchlines are quick to respond to e-mails, though. I think they would prefer not to be involved in the whole website thing.

Pardon the pun, but I came unstuck using 603 with Gibson wheels. The 603 attacked the plastic.

Does 601 work with plastic centred wheels?

I see Chronos have a cheaper equivalent to 601. Anybody have experience with it?

The official Loctite data sheets refer to plastic compatibility I believe and also state what size botttles are available. Would advise you buy from someone who turns their stock over quite fast - you don't want some that's been around for a year, which is about the official shelf life.

Has anyone looked at the original post which referred to a worm that was too tight a fit on a shaft, so how Loctite came in I don't know? Would warn that it creeps everywhere - the stuff that isn't contained sets very slowly, if at all and can end up in nearby bearings.

Enquired of Chronos about their substitute, Delta 88. It is apparently NOT compatible with plastic.

That was 8 years ago so I hope Ian has long ago sorted his worm.

What are the suggestions for preventing this? I found out when there was creep from outside cranks to axle bearings in the outside frames and it cost me a DCC chip and a new chassis (that I’m currently building).

That's easy - don't use it, although doing the job properly with press-fits does take patience. If you must use it then plan the job carefully. Shellac can be used in some applications.

Will Lichfield recommended winding cotton around the axle to prevent migration. I assume it acts both as a barrier and absorbs some of the excess. He does caution to use loctite sparingly.

Let the Loctite set in the actual joint, then clean the item in meths. That's how I assembled hundreds of wheelsets for 2mm use - plastic jar of meths, floating in a waterbath in a (cheapo) ultrasonic cleaner. Dunk items in the meths, ultrasound for a minute.
