About Mechanical Parts & Packs
Every build ends with the same question: what holds it together? This section collects the small mechanical hardware that makers reach for again and again: machine screws and nuts in the common metric sizes, self-tapping screws for plastic cases, brass and nylon standoffs for mounting circuit boards, and brass heat-set inserts that give 3D-printed parts strong, reusable threads.
The parts come in compartment boxes with each size in its own cell, and every product page lists the sizes and quantities in tables. Metric sizes are given as diameter × length in millimetres (M3 × 6 is a 3 mm screw, 6 mm long).
Like our component packs, the hardware packs are assembled to order from several boxes and priced as complete sets. Compartment counts are packed by hand by our suppliers, so a cell can occasionally hold a piece more or less than listed. Buy any 3 or more parts packs in one order and save 10% on all of them. If you need a particular size in quantity, send us a message for a quote.
