M6 thread locking/stiff screw

I asked what they used in the bike shop for such tasks and they said this stuff.

Here’s some info. about Nylon Patch screws [as per my IKEAscrounge]: **LINK**

Quite a useful device, I think.

My query seems to have brought out some useful information on this screw position retaining problem.

Thanks again to all for your input.

Thinking of the setting of the saddle gib strips, I have found two items, first on the www.madmodder.net site and then on softsolder.com.

I'll report back as to how I get on trying to solve the saddle screw positioning problem.

That's very interesting, Michael - I'd seen those before but assumed it was some sort of pre-applied Loctite, rather than nylon. Good find, thanks

Rob,

I do recall [from at least 30 years ago] reading about a similar-looking system which used micro-encapsulated anaerobic adhesive … released like the ‘scratch & sniff’ perfume samplers.

But I haven’t ever seen it on the general market

As Michael says, MEAS was very popular a long time ago, in industry. (Possibly still is? ) used on fasteners of all sizes, at the time

I have a small drawer filled with such 8 - 32 UNC grubscrews that I inherited. Try to use when locking a screw is needed, such as dutch keys. Too good to waste

Well the answer I have used to make stiff threaded screws is to place a length of thread down the hole before inserting the screw. The thread I used was model kite cord but I don't know what it is made from.

The screws can be re-adjusted it seems without loosing the stiffness.

I worked for a UK company that specialised in all forms of thread locking, sealing etc the micro-encapsulated anaerobic adhesive we applied was supplied by 3M's basically the hardener was suspended in the adhesive and when the fastener was screwed in to a thread the capsule was broken allowing the hardener and adhesive to mix most of the production was cylinder head bolts, in the case of the fasteners which a torx drive we had to make sure the adhesive was applied to the correct end assembly robots were not colour blind they were 'thick' not being able to tell one end from the other

I seem to recall that the tri lobed screws where called Taptite as they were hard and screwed straight into sheet material making their own threads. I still have some they must be at least 40 years old now!!

Just an up-date to say that following some use of the lathe, the carriage gib adjustment has not changed. So the use of a synthetic thread to stiffen the screws has provided a workable solution to this problem.
