Brass Threaded Insert Flanged Step Bushing for Plastic and Metal Parts

Qimao Metal Manufacturer is a professional Brass Threaded Insert Flanged Step Bushing For Plastic And Metal Parts factory and supplier in China. The flange gives it a positive stop so you don't push it too deep. The step design matches different material thicknesses. We've been machining these for about seven years now. Small part. Makes a big difference in how long your assembly lasts.

Product Advantages

The flange prevents installation mistakes

No flange means guessing depth. Press too far and you crack the plastic. Not far enough and the screw bottoms out. Our flange gives you a hard stop. Press until it touches the surface. Done.

Step design fits varying material thicknesses

Standard Brass Threaded Insert Flanged Step Bushing For Plastic And Metal Parts are made for one wall thickness. Our step design works across a range. The smaller diameter goes in the hole. The larger diameter pilots it straight.

Brass won't rust

Some people use steel inserts in humid applications. Six months later, threads are seized. Brass handles moisture. No red rust. No stuck screws.

Knurling or smooth — your choice

Knurling bites into plastic. Smooth OD works for press-fit into metal. We do both. Not sure which one? Tell us your material and we'll recommend.

Consistent threads, every time

We cut metric threads to 6H tolerance. Standard for most applications. Not too tight, not too loose. A screw should go in by hand without wobbling. Ours do.

Installation Tips

We've seen customers struggle with the product Brass Threaded Insert Flanged Step Bushing For Plastic And Metal Parts installation. Here's what works.

For plastic parts — Heat is your friend. Heat the insert with a soldering iron or a dedicated heat-set tool. Press it in straight. Let it cool for five seconds before touching it. If you press it cold, you'll crack the plastic about half the time.

For 3D prints — Use a chamfered hole, not a straight hole. The chamfer guides the insert and gives displaced plastic somewhere to go. No chamfer? The plastic bulges out the bottom.

For metal sheets — Use an arbor press, not a hammer. A hammer can deform the flange. A press gives you controlled force. Press until the flange touches the sheet. No deeper.

For wood — Drill a pilot hole slightly smaller than the insert OD. Run the insert in with a hex driver or a flathead screwdriver that fits the slot. Back it out and run it in again to clear debris.
