What is tolerance in sheet metal?
Generally speaking, +/-. 003” is a reasonable and functional tolerance. Hole to Hole +/- . 005” – Accuracy of the distance from one hole to another is dependent primarily upon the machinery used to process the sheet.

What is sheet tolerance?
A sheet metal tolerance’s tolerance band refers to its range of allowable dimensions. Engineers and designers take different approaches to tolerance bands. A “looser” tolerance has a larger range between the upper and lower limits. Meanwhile, “tighter” tolerances have shorter tolerance bands.
What are the general tolerance followed in sheet metal design?
A +/- 1 degree tolerance on all bend angles is generally acceptable in the industry. Flange length must be at least 4 times the material thickness. It is recommended to use the same radii across all bends, and flange length must be at least 4 times the material thickness.
What is the thickness of 12 gauge sheet metal?

|---|---|---|
| 11 | 1/8 | 53.82 |
| 12 | 7/64 | 47.09 |

What is a reasonable flatness tolerance sheet metal?
Flatness is the deviation of the surface of a sheet from a perfectly flat surface. For parts under 36” in both width and length, flatness should not exceed ¼”. For parts whose length is between 36” and 72”, the flatness variation should not exceed 75% of the flatness of a 10′ sheet for that given width.
What gauge sheet metal should I use?
What gauge sheet metal should I use? Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge differs between ferrous (iron-based) metals and nonferrous metals such as aluminum or copper.
How do you measure sheet metal thickness?
The most precise way to measure a metal’s thickness is to use a caliper. Calipers are hand tools designed to precisely measure the distance between two points. Just fit the two tips of the caliper around the metal you need to measure to determine its thickness.
What is the standard thickness of 14 gauge steel sheet?
Fourteen gauge standard steel is 0.0747 inches thick, while galvanized steel measures 0.0785 inches across. Galvanized steel has a zinc coating that guards against corrosion. In either case, the smaller the gauge, the thicker the steel. Both galvanized and standard 14-gauge steel have a variety of household and commercial uses.
