Why choose local fasteners and hardware from Communica
Find the exact fasteners engineers, technicians and makers in South Africa rely on - stocked locally for immediate projects, classroom builds and production runs. We prioritise availability, clear specifications and practical bundles so you spend less time sourcing parts and more time building. With branches in Samrand and Cape Town and a national sub-distributor footprint, many items are available for same-week collection or delivery.
Practical value beyond the part number
Our selection focusses on parts that reduce assembly time and rework: pre-cut threaded rods, captive nuts for 3D-printed panels, self-clinching nuts for thin-sheet mounting, and insulated terminals for electronics enclosures. For educators and students we offer pre-kitted assortments sized for course labs - labelled, bagged and ready to issue.

Specification callouts - pick the right grade and finish
Fastener choice is often about material, thread form and finish. For electronics enclosures and low-current assemblies we recommend stainless or zinc-plated steel for corrosion resistance; for grounding or high-current joints choose brass or copper where conductivity matters. Metric sizes are the standard for procurement - keep an eye on length and thread engagement to avoid panel deformation.
| Part | Common sizes | Typical use | Material/finish |
|---|---|---|---|
| M3 / M4 Machine Screws | M3-M4, 6-20 mm | PCB standoffs, small enclosures | Stainless / Zinc |
| Hex Bolts | M6-M12, 20-100 mm | Frame assemblies, brackets | Grade 8.8 Zinc-plated |
| Self-tapping Screws | 3.5-6 mm | Plastics, sheet metal | Steel / Pan head |
| Rivets | 3-6 mm | Permanent joins on panels | Aluminium / Blind |
Accessory bundles that save time
We assemble practical accessory bundles: PCB mounting kits (standoffs, nuts, M3 screws), enclosure fit-out packs (rubber feet, captive nuts, machine screws), and fastener assortments (screws and washers labelled by size). These bundles are ideal for lab coursework and rapid prototyping where ordering individual SKUs slows progress.
