Every Fastener. Every Dimension. Ready for CAD.

Find it. Configure it. Build it.

ScrewTube is a self-hosted parametric fastener workshop. Pick a standard fastener or start from a blank diameter, adjust every dimension, inspect it in 3D, and export real CAD geometry.

Find it

Start from an ISO preset — socket head, hex head and countersunk screws, hex nuts and plain washers — or design from scratch with just a diameter.

Configure it

Every dimension is a parameter. Change any value; ScrewTube tells you when you leave the standard table and checks geometric feasibility.

Build it

Each part is generated on demand by a B-rep CAD kernel. Download genuine STEP for engineering, or STL/3MF for printing.

All standards data is currently draft and has not been verified against the purchased standards. ScrewTube makes no compliance claims for draft data.
