M4-M12 Stainless Steel SS304 J-Type Foundation Bolt and U-Bolt for Construction
This product is a stainless steel J‑type foundation bolt and U‑type bolt pipe clamp designed for embedded fastening, structural fixing and pipe support applications. It is available in metric thread sizes from M4 to M12, making it suitable for small equipment, brackets, concrete foundation assemblies and pipe‑clamping structures.
The J‑shaped design can be embedded into concrete or used with structural supports to create a secure anchoring point. The U‑shaped version is suitable for clamping pipes, tubes, conduits and other cylindrical components to support frames or mounting bases. Stainless steel construction provides a clean appearance and is suitable for projects where corrosion resistance and long‑term service are important considerations.

Surface Treatment Options
Plain Finish
The plain finish retains the basic stainless steel surface and is suitable for general construction fastening, embedded anchor assemblies and applications where the fastener will be covered or installed in a protected position.
Polishing
The polished finish provides a smoother and brighter surface appearance. It is suitable for visible installations, equipment supports, architectural structures and projects where a cleaner visual finish is preferred.
Surface treatment should be selected according to the installation environment, appearance requirements and the type of connected material.
Application
Embedded Foundation Connections
The J‑type foundation bolt can be positioned in concrete foundations to create a fixed threaded connection for steel plates, base frames, brackets and support structures.
Pipe Support and Clamping
The U‑type bolt pipe clamp can be used to hold pipes, tubes, conduits and cables against support channels, frames or mounting plates. Matching nuts and washers help secure the pipe clamp during installation.
Equipment Anchoring
The bolts can be used for fixing equipment bases, machinery frames, light structural components and support brackets where metric threaded anchoring is required.
Construction and Structural Installation
These fasteners are suitable for building construction, concrete support assemblies, metal frames, mounting brackets and general structural fastening projects.
Workshop and Fabrication Projects
The M4‑M12 size range supports smaller fabrication work, custom brackets, pipe racks, frames and maintenance assemblies requiring compact stainless steel anchor components.
Matching Fasteners
| Product Size | Suggested Matching Fasteners | Typical Use |
|---|---|---|
| M4 | M4 hex nut, flat washer and spring washer | Small brackets and light assemblies |
| M5 | M5 hex nut, flat washer and spring washer | Equipment panels and support fixtures |
| M6 | M6 hex nut, flat washer and spring washer | General mounting and small pipe supports |
| M8 | M8 hex nut, flat washer and spring washer | Structural brackets and equipment bases |
| M10 | M10 hex nut, flat washer and spring washer | Foundation supports and pipe frames |
| M12 | M12 hex nut, flat washer and spring washer | Heavy support assemblies and anchoring |
For J‑type foundation bolts, a matching nut and washer set can be used to fasten base plates, brackets and structural supports. For U‑type pipe clamps, the selected nuts and washers should match the pipe diameter, mounting plate thickness and installation load.
Packing & Delivery
