Fast turnarounds to keep your projects moving

Add durable, production-ready threads without extra steps. Tapping ensures consistent fit and repeatability across parts.

Consistent, production-ready threads

Threads are applied with controlled tooling to ensure reliable fit and repeatability across every part.

Thread sizing guidance

Reference our detailed sizing chart to ensure proper hole dimensions for every thread.

In-house production

Tapping adds just 1–2 days to standard production times.

“The bends came out perfect (1/4” steel). Everything was tapped to perfection, the edges had a nice finish. “

Design guidelines for tapped parts

Following a few basic design guidelines will help ensure your parts are properly tapped and pass SendCutSend review.

Sizing & hole requirements

Sizing limits apply to flat parts  before bending for sheet metal

Sheet metal

Min part size (flat) sheet metal1″ x 1.5″
Max part size (flat) sheet metal23″ x 23″
  • Tapping direction is perpendicular to the main surface only
  • All threads are right-hand
  • Verify min hole sizes for your material in the Material Catalog
  • Keep the center of any tapped hole at least this distance from other cut features:
    (tap hole size ÷ 2) + minimum tap hole-to-edge distance for the material
  • The minimum tap hole-to-edge distance varies by material and thickness. Find it on each material info page.
  • Tapped holes near bends: Place tapped holes at least ½ the full die width away from the bend line. See bending guidelines.

What to expect with tapped parts

  • Parts may have light oil residue
  • Some deburring may be needed
  • Tapped holes near bends may distort and need chasing
  • All threads are right-hand

Choosing a thread type and size

UNC (Unified National Coarse) — Standard for most applications. Easier to tap, stronger in thinner materials, more resistant to stripping in soft metals.

UNF (Unified National Fine) — Better when space is limited or when working with harder materials that can support more threads per inch.

Metric (M) — Based on ISO standards. Choose if your project already uses metric hardware.

Rules of thumb:

  • Larger taps for thicker parts or higher load capacity. Smaller taps for thinner sections or tight spaces.
  • Thread engagement beyond ~1–1.5× the bolt diameter doesn’t significantly increase strength.
  • Keep thread depth ≤ 3× the tap diameter (3XD).

  • Tapping direction is perpendicular to the main surface only
  • Keep thread depth ≤ 3× the tap diameter (3XD). Example: a ¼-20 tap (.25″ diameter) maxes out at .75″ depth.
  • Through-holes will default to through-tapping under a certain ratio. Blind holes will be tapped to modeled depth under a certain ratio. Holes outside these limits need specific instruction or case-by-case review.
  • Keep tapped hole centers at least 1.5× the tap diameter from any part edge or shoulder. Example: a ¼-20 should be ≥ .375″ from hole center to part edge.
  • All tapped holes are reviewed case-by-case since clearance can vary by design.
  • Tool access: Make sure there’s enough clearance for the tap and collet to reach the hole. If nearby geometry blocks access, we may not be able to tap as requested.

What to provide at upload

In the tapping dialog at checkout, specify:

  • Tap size and matching hole diameter
  • Whether all holes of that size should be tapped
  • Through or blind
  • Desired tap depth

What to expect with tapped parts

  • Threads are right-hand
  • We machine from the model you upload. No prints or drawings needed
  • Holes that fall outside our defaults will be reviewed case-by-case
