Half Nut Hex M6 in A2 Stainless

Postby Tinpotflowers » 28 Apr 2020, 8:53pm

I am to purchase some Half Nut Hex (Lock Nut) M6 in A2 Stainless for use on Weinman side pull brakes.

The only source I found requires me to purchase @200 even though are a good price including shipping of £12 I will never use 200.

Can anybody recommend a souses recommend a place for smaller quantities.

Look on ebay. Quite a few vendors sell in packs of 10.

I have bought the toolstation ones and they are just the job. They are not £1.50 each, either.

There was one missing from our daughter's bike, but her's are centre-pulls. I believe the nuts are the same as for the side-pulls.

I just rummaged in my tin of nuts and bolts, and found one that fitted. The hex of the nut is held on by cutouts to stop it turning. The bolt end at the front is then tightened.

IIRC the nuts in the back of weinmann centre pulls are standard thickness M6 nuts. At the front of a side pull brake a (thinner) half-nut is used as a locknut.

No Brucey.
Half the thickness.

The one I fitted was full thickness, but it makes no difference.

These are blow-up photos.

I've just double-checked and Weinmann centre pull brakes are fitted with M6x1mm threaded nuts, 4.9mm length. These are ISO standard full nuts.

A half nut would be about half this thickness, and (not that it would be used here) would not have the strength to accept full bolt torque.

Sorry Brucey, I am correct.
Can't prove it coz I don't have the bike to hand.

The nuts on the back are the same thickness as the bolt heads ............... or they are in my experience from the past, and from our daughter's bike. Look at my photographs front vs rear.

well don't worry about 'proving it'; I have already wasted my time demonstrating what I believed to be the case is correct. The recesses into which the nuts fit are ~4mm depth. Standard ISO full nuts protrude by about 1mm, being about 5mm thick. Half nuts would be well underflush.
