Fabrication reference charts
Bookmarkable reference tables for the numbers that come up on every sheet metal drawing — gauge thickness, bend radius, self-clinching hardware hole sizes, and tap drills. Standard data, cited to source, with plain-English notes on how to read it and where each one trips people up.

Sheet metal gauge chart
Gauge to inch and millimeter for carbon steel, stainless, and aluminum — and why the same gauge number is a different thickness in each material.

Bend radius chart
Minimum inside bend radius by material and temper as multiples of thickness, plus a worked radius table in millimeters for common gauges.

PEM hardware hole size chart
Recommended mounting-hole size, minimum sheet thickness, and edge distance for common self-clinching (PEM-style) nuts, studs, and standoffs.

Tap drill chart
Tap drill sizes for 75% thread — UNC and UNF inch threads with the standard drill, plus metric coarse — and the formula to size any hole.
