Fasteners Shelf

A wall of labelled drawers and a few organisers beside it. Each drawer is one size: M3 x 10 DIN 7985, M4 x 20 DIN 965 HEX, M3 NUTS and so on. The label is the contents, so there is no guessing.

Fasteners are what every project needs once it leaves the breadboard: mounting a board in a case, building a frame, bolting down a motor, fitting standoffs.

Reading the labels

• M3, M4 — thread diameter in millimetres.
• The number after the x — screw length in millimetres, from 4 to 40.
• DIN 7985 — pan head with a cross slot, the ordinary machine screw head.
• DIN 965 — countersunk head: it sits flush in a chamfered hole.
• HEX — a hex socket for an Allen key rather than a cross slot.

Separate drawers hold nuts and self-tappers; the organisers hold washers, lock washers and the small things that have no drawer of their own.

How to use

1. Find the size by its label and take what you need.
2. Close the drawer and put the organiser back. A fastener in the wrong drawer is a lost fastener: nobody is going to identify it by eye among thirty drawers.
3. Do not tip leftovers back at random. If you are not sure which drawer, leave them beside it and tell us.
4. If a drawer is empty, say so: we restock what gets used.

Fasteners are included in your access within reason — a handful of screws for your project is what the shelf is there for.

Access

The shelf is in the hackspace room, so a plan that includes hackspace access is required. No induction is needed.
