For a machine one of our customers has we need to find some replacement screws that hold the cutters in place. The machine manufacturer has gone out of business so we can't obtain spares from them.

The required screws are a shouldered M5 countersunk Torx (T20) head 13mm long with a 6mm diameter shouldered portion, the shouldered portion is around 6mm long (including the countersink head). They look like a larger version of the screws that hold inserts into lathe tools.

Would anyone have any Ideas for a possible supplier?

Any suggestions welcome

Thanks

Martin

You could try *** Accu *** they manufacture, mainly stainless will do specials but can't say as to order quantity required.

These screws sound like the screws that hold a carbide tip into a holder! If you do you may be able to buy one from a local engineering supplies.

Thanks for all of the replies. Can find a lot of similar ones but nothing exactly matching our requirements. I've given details to one of the suppliers but they have come back with a price of over £2000 for 500 custom made screws. Back to searching.

Try speaking to similar tool suppliers. I used to be involved with a lot of special cutting tool designs but these always used standard parts from the likes of Sandvik.

Could you buy M5x13mm Torq screws and turn a shoulder piece and secure with locking fluid.

Whilst I have not used them for a few years, the 'Non Standard Socket Screw' company (in Birmingham I think) might be able to help. I have purchased custom made batches of SS and HT SHCS in ridiculously long lengths and the prices were definitely reasonable at the time.
