Indicative Pricing With Allowance for P&P

These things are tiny any usually sold in packs of at least 20 for about £1.50. You’ll actually use very few of these, perhaps 4 making an effective price of around 40p each.

These must be a small round head as some designs include cavities for the head. You could use a non phillips head fitting but it isn’t recommended as the screws are just a bit harder to handle.

So far these is only a need for two of these and you can order two via the link above for 75p each. You might as well buy a few more for little extra cost in case we use them again. As a compromise on indicative price I’ve suggested 50p each.

Allen key head looks good too. Stainless steel or black is nicer but costs more.

Indicative Pricing With Allowance for P&P

These are quite a rarely used size which makes the unit price effectively more than the other lengths of this machine screw. You could just buy a pack of two as that is all that is used so far in AuthentiKit controls, which would make these about 75p each. As there may be occasional further uses an indicative price of 35p has been chosen.

ATK1C425 M4 Countersunk Screw x 25mm

M4 Countersunk flat head phillips head machine screw 25mm long

  • Manufacturer: Various
  • Product ID: Various

Use either zinc plated or stainless steel. Get philips head if you can as the PH2 but fits them very nicely, otherwise pozidrive will do. These tend to only get used with Roten6003 units where for stability you need the screw to go all the way through the base with some clearance.

These are not a common length with AuthentiKit designs and as you tend to have to buy packs of at least 10 the unit price is effectively higher than other lengths.

Pozidrive is an option if you can’t get phillips head.

These things are tiny any usually sold in packs of 50, 100 or even 500. Unfortunately we don’t use these much in AuthentiKit controls and you will probably only use 2, maybe 4. You may be able to get a pack for as little as £2 putting the unit price at £0.50. With a bit of luck though you’ll have some lying around.

You can get away with as little as 5mm in length and 8mm at a push. You’d probably also get away with M2.3
