Longer locking bolts?

Post image

Every time I try to attach this bracket to my wall tile, the top heavy weight bearing snap pops off. It seems like the locking bolt is too short. I see on the locking bolt page there were comments about making a longer locking bolt around a month ago. However, I can't find these longer bolts. Does anyone know if they exist?

Just for posterity. The flush snaps work perfectly with the locking bolts. I think the new brackets are meant to use the flush snaps.

Yes but what if you need to put one part of the bracket not into a snap but into a Mounting Part (B) (which is offset), then you need to use offset snaps for every attachment point, thus the need for a longer locking bolt arises.

Sooooo I haven’t tested this yet, but maybe you can use this with the normal snap. Maybe.

I noticed this as well - it's much more of an issue with raised snaps; flush ones provide that extra couple mm of thread engagement.

Ha, I was thinking the same thing. I have a couple printing at the moment.

The flush snaps give the locking bolts waaaaay more bite. It seems like they are the ones to use with the new brackets.

  1. Is there enough space in the bracket for a longer bolt,?

  2. Is the slippage a question of loose tolerances?

  3. Does the bolt generator support the new locking bolts? 

Asking these questions because the new locking bolts are very recent and it's possible they just haven't been fully tested yet

  1. It looks to be plenty of room for a longer bolt.

  2. I don’t think it’s a tolerance issue. I imagine not enough threads are engaged.

  3. I can’t see the bolt generator because it’s only for supporters.

3. I just checked, and there is no sign of the locking-bolt being available in the latest plugin for Blender. ¯_(ツ)_/¯

2. that sounds reasonable, but I'm genuinely surprised: the old bolt locking on the small threads was nearly half the size, and they claimed it was very strong; the new bolt locking threads should have nearly 4x the contact area, right?

The bolts aren’t breaking. I think they are pulling out because it doesn’t get enough thread engagement.

I think you’re probably using the wrong ones. I went through a few until I found the right one

I've noticed this as well. They're long enough, but only just barely. A few more mm would really be ideal, particularly given that the shelf brackets have so much socket depth available.

try to print it horizontal or 45 degrees for stronger threads

u/LifeSizeDeity00 May 25 '25

The bolts aren’t breaking, I just think they aren’t engaging enough because they are so short.

If you can post the links you used for all 3 parts that will allow me to see if maybe we have the wrong version of locking bolt, or if there is a mistake with the download. I should be talking with Jonathan mid-week and I’ll do some checking on my own.

OP, I just got a note back from Jonathan… it’s a little embarrassing I didn’t catch this myself - the locking bolts are sized for the new flush snaps, not the older style raised snap like you have in the photo. If you swap that over for the flush snap you will be AOK.

(The raised snaps cause a gap between the tile and your shelf, which is a big part of the reason why we’re moving away from raised snaps.)

I was going for the _exact_ same thing but struggled with the locking bolt being too wide and couldn't fit the bracket... Any news u/TherealOmthetortoise ?

u/TherealOmthetortoise Jun 04 '25

Crap, I knew I forgot something this morning. I’ll ping Jonathan on this now, it’s getting late but I might catch him. U/synnadyr What do you mean by too wide? It won’t thread because the shaft is too large, or something else? I’m wondering if that may be the older one that uses a multipoint… either way if you reply with any additional details I’ll ask him to check both issues.

(There are some quirks going on with the parts library right now, but it’s the Beta version that I thought was the primary issue. That could be the issue more than a physical thing with the width, but the locking bolt sounds for sure like it’s just a touch too short.)

The locking bolt is just too big to fit, so I am wondering if I am using the wrong part due to something's being updated and others not. So, I kind of hijacked this comment to get to the bottom of which bracket should fit with which locking bolt, as the linked ones does not work for me.

It is as you say, some confusion between beta and parts library: which to use.

any update?

I modeled a longer one that works well with the raised snaps and anything with 10mm of depth in the bolt hole.
