I'm hoping someone on the Forum can help me here.

I'd like to find someone that can make a set of 4 screws for me, in order to replace some damaged items.

Screws are M6 thread and need to be either SCH or Torx but the length/profile/heads are not standard so will need to be adapted from existing screws or made as 'one offs'.

I lve near Wisbech, Cambridgeshire and don't own a lathe to make them myself, hence the request.

Anyone?

I can't really help, but suggest that more details of the intended use would help.

Hello from Wales

Changing the length is easy, as long as it involves removal of metal. Other changes are not so easy, it depends on what shape you need, what shapes are available in that length, and what material. So, if you can offer a sketch or a photo of what you need, as well as some detail of what it is for, we can offer further (perhaps better) advice.

Regards, Tim

Reducing length, or OD of a M6 SCH screw is fairly easy, in most cases.

How about some details of what you are looking for as a end product?

I am in Peterborough, if that is any help.

Send me a PM?

LH screw:-

o/all length = 37.3mm

Head diam = 10mm

M6 thread

Threaded portion (to the shoulder) = 9mm

Plain shank (under head to the shoulder above the thread) = 26mm

R.H screw:-

o/all length = 26mm

Head diam = 9.8mm

M6 thread

Threaded portion = 12.5mm

Plain shank = 9.5mm

Head thickness = 4mm

Max torque loading on these will be 4.5Nm

I think the above covers all the detail and I'd be looking for 2 off of each screw.

Those are stndard firearms components so take a look in one of the big gunsmithing catalogues or portals and you will probably find them there

Have you tried Sterling Nut and Bolt in Royce Road, Peterborough? They have a minimum order of £5 + VAT, so your 4 screws will cost you £6.

Might be worth a phone call or better a visit, especially if you can take examples.

Bob - You're correct in that they are standard gun screws but these are slotted head. I'm looking to replace them with SCH or Torx before the slotted heads get too chewed up. The screws are readily available as an upgrade in the USA but not in Europe. USA stores won't ship internationally because of ITAR (International Traffic in Arms Regulations).

Howard - Hadn't thought of Sterling. I'll give them a go tomorrow but surely they only deal in run of the mill stock?

In my experience, Sterling keep a wide range of types. Got to be worth visiting to ask the question, and seeing what they can offer

If they are, indeed, gun smithing screws, surely the place to get them would be from a gunsmith? Dave at Whittlesey would likely sell you a couple of each. Probably slotted - they do not get damaged if treated properly with the appropriate turn-screw.

Then there is Elderkins at Spalding. Plenty of others, too. I’m thinking they might be for ‘scope mounts for the second example, although a bit big, maybe?

Hello Iain,

If they're for an airgun, have you tried T. W. Chambers or John Knibbs?

Many thanks for the responses chaps. Much appreciated.

The bolts are the bedding bolts for a CZ rimfire.

Replacement screws (i.e. same ones) can be found in abundance but isn't what I'm looking for. As mentioned in my earlier post, what I'm chasing is to upgrade the bolts, replacing the slotted head with either SCH or Torx.

Agreed, slotted heads do not get chewed up if treated correctly but 1. you don't always have the luxury of guaranteeing that previous owners have used the correct tools (it's secondhand) and 2. I've given up trying to find a 10mm wide screwdriver bit that fits in to a 1/4 drive torque wrench.

Have you looked in Brownells They have a lot of torx screws.

A thought -

If a supplier is not willing to supply because sending arms abroad is forbidden, order them 'For repairs to a Vintage Car'. It is not clear how a screw can 'always' be identified as 'arms' - what happened to the American idea of interchangeable parts?

Hope this might help

There are 10mm screwdriver bits with 1/4" hex fitting. And adaptors for hex drive to 1/4 square. And ditto with 5/16 hex and 3/8 drive.

There is no distinction between engineering and ingenuity.

Cheers, Tim

Iain, replace with standard screws and grind a screwdriver (turnscrew to fit) and have a couple of spares just in case the previous owner slipped already!!

By the looks of your screw on the left the tor’s or hex socket will be fairly small for the size screw as there is no real head to be able to rotary broach a decent size into. Surely the screw on the right is a straight mod from a shoulder bolt.?

Tried Sterling Nut & Bolt in Peterborough without success (it was worth a try - thanks for the suggestion Howard).

I've got some standard sized SCH screws so I'll adapt those. It won't be a perfect or pretty job but it'll at least get me to where I want to be.
