I think you’ll find the bench bolts will work fine. I put some on my bench when I built it 45 years ago and the base is still as Rock solid as when built it. Back then the bench was moving to new job sites every week or two and I wanted something that would break down flat, sort of like IKEA designed stuff. The last time the bench moved was about 1998.
Every 5 years or so i snug them up a little. Be aware that most bench bolts I’ve seen are for 1/2” bolts, And are designed for 1” thick material or have the bolt center 1/2” from the surface to sit flush, so you have to allow for that.

The cost is outrageous even if it is for four. Try googling for bed bolts or bunk bed bolts…
I wasn’t sure about the price because I’ve never bought this kind of thing before. But now that you mention it, I suppose it is a bit expensive. I wonder if bed bolts are as strong though. Being for beds I’d have to assume they are.
Thanks for the recommendation.
With regard to the original question, I see 3.5mm diameter drills at Grainger of various kinds and lengths. They have a high speed steel drill for about $10 US that is 112mm overall with 72mm long flutes, although it is marked for metal working. Remember that sometimes when you are boring through two pieces, as in this case, you can clamp up the pieces, bore as deeply as possible, then unclamp and run the drill into the hole in the 2nd piece. Since the first, overlaying piece is out of the way, you can continue that additional depth. You do want to be able to go deeply enough into the 2nd piece that the hole will start and guide the drill.

By the way, here is a link to the full search for long 3.5mm drills at Grainger. There are 4″ long 3.5mm drill towards the bottom.
I don’t know if that link will work or if you have access to Grainger in the UK. Some of the drills are from France, so perhaps just having their names will help you find them if you still want to go that route.
22 October 2019 at 8:12 am #620425Hi Mark68,
I had exactly the same problem with my bench build so I ended up using some hex head coach screws (similar to ones I used to attach the vise) and then because I had no intention of moving my bench I bored a hole to take a wooden plug to hide the heads. I’ve been using the bench for a year now and it is as solid as the day it was finished.
BTW if you Google M10 barrel nut you will find quite a few hits, some as cheap as 48p each…

Isn’t it just a dado?Another idea would be to use bed hardware
the plate with the hole on the leg-frame and the hooks in the dado on the apron (not tested).
Hi Paul
Thanks for the reply. The ‘M10’ search results are very similar to the other search parameters I used; M10 furniture bolts and barrel nuts.
The problem is trying to find M10 x 120mm furniture bolts with the requisite barrel nuts in one package. So much so I think I have to just, buy the veritas bolts. Sometimes I find Google more of a frustrating experience than anything else.
Incidentally, I did find furniture bolts and barrel nuts of the required measurements, but when I added p&p to the total, it wasn’t far off the veritas asking price of £29.95.
In the end, I went for Turbo coach screws. I’ll fasten two into each leg and hopefully, that will be that. It was the cheaper option and seeing as the bench isn’t going to be moved, it should be fine.
Thank you all for the help and advice, it is appreciated.
