Blocking Caps

[foxychick]

Anyone know where you can get the plastic blocking caps to insert in the hole where the bottle cage bosses screw in?

Never seen such a thing - I just get some allen bolts (I think they are M5) in stainless steel, and a washer to suit, and screw that in. All the unused threaded bits on my bikes are done like this, even on the dropouts.

could try at the LBS; some new bikes come with such things fitted. Plastic screws exist and they are just the job for blanking purposes too.

Mad thought; would the little end bit (with a little whittling to size) from a BIC ballpoint fit....?

I use these neat button head stainless steel bolts. M5 x 10mm. Also useful for blocking off any other 5mm unused threads

...or screw covers?

...or just stick a stainless bolt in there? ETA - as above

You could try these - come in different colours too!

Might be slightly too big as thread narrows the m5 hole down a bit

That's surely the way...... Then if you lose (for example) an M5 screw securing something else whilst on the road, you have an available spare!

Grub screws with some thread lock might be a neat way of doing it if bolts are not sufficiently low profile. You could finish it off with a drop of wax.

Hi,
Button heads all day long, that link above is very cheap too.

My better bike has all the unused bosses filled with disc rotor bolts which have a button torx head and as I had so many of them they all match.

Same here.

Hi

...with some thread lock

I wouldn't recommend thread lock in this case. Even the weaker varieties commonly available have a 6Nm breaking torque, which can be enough to cause problems

I agree that allen key grub screws are problematic if they need any high torque value to shift them. I would perhaps suggest that if you want to use such screws, a few turns of PTFE tape is usually enough to seal and make the screws stay put whilst allowing them to be removed later if required.

Never heard of such a thing OP.

Surely a still untapped opportunity for the carbon marketing teams?

I recall working on motorcycles where all of the allen bolts were wearing little caps, an ebay search for Allen bolt covers reveals you can buy them.
