Buy fasteners & hardware in South Africa with parts you can trust
When a project stalls because you can't find the right screw, standoff or rivet, time and budget are lost. Communica keeps thousands of common and specialist fasteners in local stock so South African makers, students, technicians and procurement teams can finish builds on schedule. Fast access, clear specs and branch collection from Samrand, Pretoria CBD or Cape Town mean shorter lead times and fast VAT invoicing for campus purchases and company accounts.
What we stock and who it's for
Our ranges cover machine screws, self-tapping screws, hex bolts, nuts, washers, standoffs, spacers, rivets, cable ties and panel hardware - sizes for PCB mounting, sheet-metal assembly and 3D-printed enclosures. Popular maker-friendly brands and industrial lines are available; explore our categories on the Collections page to match parts to your project.
Fastener selection - pick the right part the first time
Choose by thread, diameter, length and head style. For electronics assemblies you’ll typically use M2-M4 machine screws with nylon or metal spacers; for sheet metal, self-tapping or thread-forming screws work best. Consider material: stainless steel for corrosion resistance, zinc-plated for general purpose, brass for conductivity where required. For education labs, low-cost bulk packs keep spares on hand without overspending.

Compatibility and accessory bundles
Match screws to nut thread form and hole clearance. For PCB work, pair M3 pan-head screws with nylon washers or PCB nylon nuts to avoid shorts. We offer pre-packed bundles: PCB mounting kits (screws, spacers, washers), enclosure hardware packs and high-strength bolt kits for mechanical prototyping - ideal for labs and classroom projects.
