These snap-off M4 bolts with sleeves are designed to be fairly universal in their size.
They have 'snap' points at varying lengths, allowing you to cut down or snap off the thread to shorten down the bolt for your application.
This removes the need to get perfectly sized screws as you can easily change it depending on your requirements!

Hi, guys. My name is Darrel and I'm head of the tech team here at Locks Online. Thanks for taking some time to tune in and have a quick look at one of our product review videos. Now, we put these short little videos together to be able to give you, our customers, the opportunity to see the products that we have to offer in hopefully a little bit more detail, in the flesh, so to speak.
A popular product that we have on our website is a very, very simple product. It is actually a M4 bolt that's designed to work with door furniture that requires to have a bolt through assembly. Now, most door furniture, you can either screw into the timber via using wood screws or, depending on the lock and the application, you may want to consider actually clamping the two handles together. It makes for a stronger and a sturdier sort of set up. It can be used also in other different applications, but that's what the majority of this particular type of set up is for.
Now, as you can see here, this is an M4 thread, but it has these cut-outs here and the idea is that you could cut this off, depending on the length. I'll get some measurements on that in a minute. And there's also then the sleeve, what the call here, the M4 bolt sleeve. It has a Phillips head at the end and both ends have Phillips. And the idea is then you are able to put one into the other and be able to screw those in there and be able to clamp up the two handles together on a door. So, therefore, then, making for a much stronger set up than you would normally get by just using wood screws, that if they're used aggressively, could actually rip the screws out of the actual door itself. So, there's the reason for this particular application.
Now, the overall length of this here, if I was to put that over there, you can see there's about 65mm from one end to the other. If I was to screw that in, say, to the first thread there, which I would say is a reasonable amount of thread to put in there, then the overall fixing then, you're looking at around about 75mm. So, 44mm doors, even 56mm doors, I wouldn't see there being a problem using this particular type of fixing.
But listen, if you need a bit more information on this or you want a bit more of advice, by all means, pop us over an e-mail, use the live chat that we have, or simply do it the old fashioned way and pick up the phone and give us a call. They're sold in pairs, by the way, so you know you need to buy one pair per handle set. But, like I said, if you need a bit more information, pop us over a call. So from me, Darrell, and all of us here at the Locks Online team, thanks for taking the time to tune in. Hope the video has given you a little bit more information. Hope to see you soon. Take care now. Bye.
