Product Overview and Core Value
A stainless steel hex insert is a threaded insert component used in plastic, injection molded, metal, wood, or structural parts. It provides a metal internal thread for screw or bolt assembly, making it suitable for products that need repeated installation, maintenance, or long-term fastening.
For injection molded parts manufacturers, the key is stable assembly. The outer hex size must fit the part correctly, the internal thread must run smoothly, and the insert must stay secure after installation.
The hex outer body helps the insert hold more securely inside the part and reduces the risk of rotation during screw tightening. Stainless steel material supports rust resistance, corrosion resistance, and long-term use.
Clean internal threads help screws install smoothly and reduce jamming or rework. Thread size, thread depth, outer hex size, height, tolerance, material, and surface finish can be customized according to drawings or samples.
Custom Options
As a custom threaded insert for plastic parts, this product can be produced according to drawings, samples, or assembly requirements. Key details should be confirmed before bulk production so the insert can match the final part and installation process.
| Custom Item | Available Options |
| Internal Thread | Metric thread, inch thread, custom thread size, thread depth |
| Outer Hex Body | Hex width, height, chamfer, tolerance, anti-rotation fit |
| Material | Stainless steel 304, stainless steel 316, or specified material grade |
| Surface Finish | Natural finish, passivation, polishing, or project-based surface requirement |
| Production Basis | Drawing-based production, sample-based production, OEM / ODM customization |
| Packaging | Bulk packing, bag packing, label, carton mark, or customer packaging requirement |
Production Control and Inspection Support
For custom stainless steel hex insert projects, production capability and inspection control need to work together. The insert must have an accurate outer hex size, smooth internal thread, stable height, clean chamfer, and consistent material quality to fit correctly into plastic, metal, wood, or structural parts.
Zeyao Hardware supports custom fastener production based on drawings, samples, and technical requirements. Depending on the product structure, production can include turning, milling, threading, grooving, cold forming, and CNC machining. Before shipment, key details such as internal thread size, thread depth, outer hex dimension, height, chamfer, surface finish, and packaging are checked against the approved drawing or sample.
This helps buyers reduce assembly problems, insert rotation, thread jamming, batch variation, and quality disputes during bulk production.

FAQ
Q: What is this insert used for?
A: It is used to create a stronger internal thread inside plastic, metal, wood, or structural parts. It is especially useful when the product needs repeated screw assembly or better thread durability.
Q: Is it mainly used for injection molded parts?
A: Yes. Injection molded parts are one of the most common applications. The insert helps plastic parts gain a metal internal thread and reduces the risk of thread stripping caused by repeated screw installation.
Q: Can the size be customized?
A: Yes. Internal thread size, thread depth, outer hex size, height, chamfer, tolerance, material grade, surface finish, and packaging can be customized according to drawings or samples.
Q: Can you produce according to samples?
A: Yes. Samples can be used for size checking, thread confirmation, surface finish reference, and production evaluation before bulk manufacturing.
