PS-E39 Embedded Weld Nut
PS-E39 Embedded Weld Nut for bottle bosses, rack bosses, frame inserts, and accessory mounting points. Includes mapped product render, dimension drawing, asset status, engineering notes, and CAD request support.
Engineering Role
This embedded insert provides a controlled threaded or locating feature for bicycle frame programs. It is intended for weld-in, brazed, bonded, or press-fit interfaces where tube wall thickness, boss seat, and thread protection must be reviewed before sampling.
PS-E39 Embedded Weld Nut is mapped from the PremFixer technical asset library with source reference 646-113-270. The page keeps the render, drawing, and CAD status together so engineering and sourcing teams can review the item before sending a formal RFQ.

Dimensions & Interface Control
Use the mapped dimension drawing to confirm thread specification, boss height, flange or shoulder form, weld seat, and frame tube wall thickness. Final production dimensions should follow the customer drawing, mating component, assembly stack, and bicycle brand service requirement.
- Main image and dimension drawing are linked in the media panel for quick visual review.
- Confirm mating parts, frame material, coating stack, torque path, and service access before sampling.
- Custom length, profile, thread, hole position, finish, and packaging can be reviewed during RFQ.
Material, Process & Finish
| Material direction | Steel, stainless steel, aluminum, or drawing-specified material |
|---|---|
| Process direction | CNC machined, cold formed, welded, brazed, or bonded insert |
| Finish options | Plating, black coating, anodizing, or finish prepared for frame painting |
Material and finish are selected against the drawing, corrosion target, weight requirement, and mating assembly. Alternative grades or coatings can be reviewed when the application needs higher strength, lower weight, better wear resistance, or a specific cosmetic target.
Quality & Traceability
PremFixer can support drawing-based inspection for thread gauges, outer diameter, height, concentricity, coating thickness, and weld-seat appearance. Batch traceability, incoming material checks, coating reports, hardness checks, salt-spray validation, and dimensional reports can be prepared according to project requirements.

Start RFQFrequently Asked Questions
Confirm fit, drawing control, finish options, and documentation before RFQ.
Q1 What installation method is used for these weld nuts?
These are embedded weld nuts installed via TIG welding or brazing into the bicycle frame. Thread protection during welding and post-weld cleaning should follow the frame manufacturing procedure.
Q2 What thread sizes are available?
Standard M5 × 0.8 for bottle cage and accessory mounts. Custom thread sizes and lengths available per drawing.
