Being an Engineer S7E12 Flash Training: Design for Assembly: Why Fewer Screw Lengths Makes Everything Easier

When engineers design parts in isolation, it’s easy to unintentionally introduce dozens of slightly different fastener lengths into an assembly. That might not seem like a big deal during CAD, but it becomes a real problem on the shop floor.
In this short engineering pro tip, Pipeline automation engineer Mark Blakey explains a simple strategy he uses in SOLIDWORKS to standardize screw lengths across an assembly. By adjusting counterbore features and editing the Hole Wizard sketch dimensions, engineers can design parts so the same bolt length works across multiple locations.
The result: fewer fastener types, simpler purchasing, faster assembly, and fewer mistakes during build.
Mark also explains why this matters in critical applications where proper thread engagement, torque requirements, and thermal cycling all depend on using the correct bolt length.
If you’ve ever assembled a machine and had to hunt through bins for slightly different screws, this tip is for you.
