We do not manufacture brass threaded insert just for specification. We cut them to perfect fit that hold, moves, flexes, and shrinks over time. Every batch we dispatch goes to through tight quality checks, quality thread gauge inspections, and real press-fit logic.
Required heat set insert for Nylon, Flanged press-in for glass filled PC? We have manufactured every type of Brass Threaded Insert in the book. We complete one batch of M8 inserts that loose in field installs. We changed knurl geometry, and ran a 15 piece test, and looked at it.

We make threaded inserts for everything from injection molds to aerospace grade enclosures. Each design type serves a different job. Geometry matters.
We manufacture all of these above listed. Some batches need OD tolerance maintained down to ±0.05 mm and some need to thread pitch to be looked within class 2B. If your part calls for something not off the shelf, we can do it.
Brass straight-knurled insert designed for press-in mounting in plastic housings and injection-molded components.
Brass diamond-knurled insert designed for press-in installation in plastic injection molding.
Brass diamond-knurled insert designed for heat-set installation in injection-molded and 3D-printed plastic parts, electronics assemblies, and industrial plastic components.
Brass diamond-knurled insert with chamfered thread entry, designed for press-in installation in injection-molded and 3D-printed plastic parts.
Brass threaded insert with angled knurling, designed for heat-set installation in injection-molded plastic part.
Brass threaded insert with internal ISO metric M6 thread and straight knurling, suitable for installation in plastic components.

You will not find unclear specs here. We thread on Swiss type lathes, clean taps, and bore check every critical batch.
In our one order a plating vendor left buildup inside M5 threads. We checked go gauges on all 2000 Pieces and caught 180 pieces that failed. Cleaned, recut and rechecked. That is why our threads work when they hit the line.
Unlike generic Brass Inserts , these are all about threads that hold under load, vibration, and torque.
| Insert Type | Install Method | Tools Needed | Strength Profile |
|---|---|---|---|
| Press-In | Manual/Press | Arbor press, jig | High pull-out resistance |
| Heat-Set | Heated tip | Thermal driver | Medium to high, fast fit |
| Self-Tapping | Screw-driven | Driver gun | Quick install, moderate strength |
| Expansion | Threaded bolt expands body | No external press | High lock after set |
Every insert type behaves differently. Press-ins need sharp OD knurl. Heat sets demand tapered bodies and chamfer rings. Expansion types? We tap those slots and ream bores to ±0.05 mm so they flex clean.
This is where our inserts actually use:
Each batch and order has a story. One drone OEM requested to pull out data at 800N for their carbon reinforced parts. We tested on 5 blocks, pressed 10 samples testing and delivered.
We cut threads with carbide taps and single point tool. It is depending on thread depth and geometry. After cut:
Some of our flanged closed end inserts need a blind thread to ±0.10 mm from the base. It is mean by setup checks, tooling stop, and thread relief bore matching.
We do not ship threads we would not bolt into ourselves.
Threaded inserts look simple until something goes wrong and it does. We have witnessed everything and we try to avoid it.
Plastic may have cracked because of knurl height was too aggressive. We can fix with by maintaining perfect OD and testing in five ABS pilot blocks.
Some materials are smear. We had one order of C385 that pushed a burr on thread exit. Our QC team caught it during GO/NO-Go testing. Swapped the tap, added a pass with air-blast, and shipped clean threads.
Collet was off by 0.03mm. We did not wait for response and re-ran the lot. Client never found the issue.
Threads came back nickel plated with tight pitch. We now oversize threads 0.02 mm before plating and run 100% gauge test after.
We do not expect inserts to install “close enough.” We make them right and we ship them.
Getting the result of 1,000 parts right is one thing. Getting them right each time, six months later? That is where our process we holds
We do not just repeat the drawing – we repeat the manufacturing.
Yes. We manufacture non-standard threads for OEM clients across our entire range of Brass Products. We need a clear thread pitch and tolerance zone in the drawing.
Yes. We work with RoHS and CE plating partners for nickel, tin plating. Threads are cleaned and gauged after plate. We do not ship plated threads unless they pass fit.
We cut closed end inserts all the time. Some are as short as 5 mm with only 3-4 full threads. We use short form taps and single point threading to control thread start and finish.
Yes, we handle efficient shipping to the USA, UK, and throughout Europe. We are a leading supplier for Threaded Inserts in the Netherlands and provide high-quality Brass Threaded Inserts in Germany, as well as other international territories.
Yes, Every order goes through strict quality checks. We can send inspection reports, material certifications, and dimensional verifications to meet your requirements.
Simply you have to send product drawing or sample for diameters. Then we offer you quick quote. We also support competitive pricing for bulk quantities.
Whether you need press-in, self-tapping, closed-end flanged inserts, we machine them with thread-first accuracy and full inspection.
We ship regularly to the USA, UK, Europe, and Asia.
