Bench › Bulk Parts Packs

Bulk parts packs: technic parts and compatible building blocks by the handful (8 packs)

Deep mixed packs for people who build every weekend and keep running out of the same four pieces.

What sits in this drawer

There is a point in every building habit where sealed sets stop making sense. You are not following instructions any more, you are designing, and what you need is quantity: forty of the same friction pin, a hundred bushes, enough beams to brace a frame twice. These packs are built for that point. They are a parts library, not a model, and the only picture on the front is of parts.

Each assortment covers the regular-sized mechanical parts that technic building leans on — bricks, bushes, pins, shafts, bolts, connectors, chain links. They are compatible with LEGO® Technic and other building blocks of the same system, which is why classrooms running EV3 kits buy them to keep a set of trays alive. The large packs ship with a random colour mix: we would rather give you the piece count than hold a run back for a matching shade of grey.

Questions about this drawer

Which brands of building blocks are these compatible with?

Anything moulded to the standard technic system, including LEGO® Technic. Pin diameters, axle cross sections and stud spacing all match.

Why is the colour random?

Because a bulk pack is for structure, not for show. Holding back a run until one colour is in stock would double the lead time and the price.

Can I buy these as replacement parts?

That is their main job. When a robotics kit starts to thin out, a bulk group refills it far more cheaply than ordering single pieces.

One drawer over

This is one drawer of a longer bench; the ASTEM collection covers the rest of the job. We measure before we pack: technic gear teeth, axle cross and pin fit, so the building set you open is compatible with the LEGO® parts on your table. Most of what we fix comes from builders writing in; a customer note about the experience of opening a bag beats any lab test.
