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.

Sheet metal tapping guidelines

Sizing & hole requirements

Sizing limits apply to flat parts before bending for sheet metal

Sheet metal

Min part size (flat) sheet metal	1″ x 1.5″
Max part size (flat) sheet metal	36″ x 46″

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).

Available tap sizes for sheet metal and plastic

Model your hole at the size listed below for the tap you want. We automatically resize laser cut holes to the correct drill size.

Thread/Tap Size	Hole Size (in)	Hole Size (mm)
4-40	0.091″	2.32
6-32	0.116″	3.00
8-32	0.138″	3.51
10-32	0.164″	4.17
1/4-20	0.209″	5.31
1/4-28	0.221″	5.62
5/16-18	0.266″	6.76
5/16-24	0.278″	7.07
3/8-16	0.323″	8.21
3/8-24	0.341″	8.67
1/2-13	0.435″	11.05
1/2-20	0.459″	11.66

Additional tapping resources

If you’re designing parts for tapping, these resources may help:

Pre-flight checklist for sheet metal and plastic

File is in a format that we accept (2D: .dxf, .dwg, .ai, .eps; 3D: .step or .stp)
All holes and cutouts are at least 50% material thickness for laser cut parts
All holes and cutouts are no less than 0.070” for most waterjet cut parts
All holes and cutouts are no less than 0.125” for all CNC routed parts
File is built at a 1:1 scale, preferably in inch or mm units
2D files: all objects on the same layer, text converted to outlines, no open contours, all shapes united or merged, floating interiors bridged or stencilized
3D files: single solid sheet metal body, uniform thickness with a face at every edge, modeled at stock thickness with matching bend specs
All stray points, duplicate lines, empty objects and text areas have been removed

CNC Machined Billet tapping guidelines

Sizing & hole requirements

Sheet metal

Min part size: billet	1″ x 1 x 1″
Max part size: billet	7″ x 7″ x 12″

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

  I ran into an issue replacing an old sink and needed a stainless steel spacer.  SendCutSend was amazing!  Awesome AI Tool to help me design exactly what was needed, round the edges to match my sink and get the order placed!  Very reasonable pricing and about a week and a half later, I had my spacer!  Will definitely use them again!

  What a great company, website is easy as can be, part was machined perfectly, every step of the process was updated VIA text and part was shipped and delivered days ahead of schedule at a price that can't be beat. I work in R&D at a company with 50+ CNC machines and prefer to use these guys because our machines are all running production programs and down time to do one-offs is a hassle. Send Cut Send is a true resource that even well equipped shops can benefit by using them.

  Needed some custom panels for my audio build and was running out of ideas so went to their website and used their templates and made the panels i needed to my measurements and a few days later they arrived. They were just how i wanted. Will be using them again in the future.

  First time experience with SCS and they deliver excellence. Sent over dxf file of vintage carburator spacer suited for my 1947 Studebaker M15A. Selected the 1/2" G10 fiberglas isolator and pressed go. Rapid service and dispatch. Got the final product delivered to Norway and same day installed with perfect results. Very happy customer!
