Description
High-Performance Carbon Carbon Composite Fasteners
Our carbon carbon composite fasteners give engineers a complete range of high-temperature solutions for furnace assemblies. This product family covers CFC bolts, nuts, screws, threaded components, and custom hardware made for demanding thermal environments. Each fastener provides reliable performance inside vacuum furnaces, sintering systems, and thermal processing equipment.
We design these fasteners with C-C composite to deliver stable strength, low weight, and consistent behavior during rapid heating and cooling cycles. This makes them a dependable choice for any application that requires durable high-temperature fastening.

Key Features of Carbon Carbon Composite Fasteners
Engineers choose carbon carbon composite fasteners for several key reasons:
High-temperature stability
C-C composite keeps its strength at extreme heat levels where metal fasteners deform.
01
Low thermal expansion
The material ensures stable clamping force throughout furnace cycles.
02
Lightweight structure
CFC fasteners reduce thermal mass inside the hot zone, improving heating efficiency.
03
Oxidation resistance
The composite structure helps maintain durability and thread stability.
04
Long service life
These fasteners handle rapid temperature shifts without cracking or warping.
05
Customized Fastener Solutions by SHJ-CARBON
At SHJ-CARBON, custom fastener production is more than machining parts to size. We work side-by-side with engineers to develop fastening solutions that perform reliably inside high-temperature furnace environments. Our experience with carbon composite materials allows us to support customers from concept through final production.
Engineering Support for Application-Specific Designs
Every furnace layout has different stress points, thermal loads, and structural constraints.
Our engineering team reviews your drawings, temperature requirements, and mechanical demands to create fastener geometries that deliver accurate fit, stable clamping, and long service life.
Guidance on Selecting the Right Composite Structure
Different carbon-carbon composite grades behave differently under heat, load, and cycling.
We help identify the composite type that best matches your project-whether you need higher stiffness, improved wear resistance, reduced thermal mass, or better dimensional stability.
Precision Machining With Tight Tolerance Control
We manufacture custom bolts, nuts, and threaded hardware using controlled C-C materials and dedicated machining processes.
Each fastener undergoes dimensional checks, thread verification, and visual inspection before shipment to ensure consistent, furnace-ready quality.
Flexible Prototyping and Short Production Runs
For development work or system upgrades, we support low-volume or prototype orders with quick turnaround times.
This approach allows you to validate new fastener designs, test performance in hot zone conditions, and refine specifications before scaling production.
At any stage-design, material selection, machining, or prototyping-our goal remains the same: to deliver custom CFC fasteners that improve the stability, efficiency, and reliability of your thermal processing equipment.
Industry Applications and Use Cases
Our fasteners work across many high-temperature sectors, including:
- Vacuum furnace hot zone frames
- Graphite fixture assemblies
- Heat-treating and sintering equipment
- Semiconductor processing furnaces
- Carbon composite support structures
Their stable performance helps maintain the strength and alignment of thermal processing equipment.
Product Features
Each fastener offers:
- Precise machining and thread accuracy
- Uniform C-C composite structure
- High strength under load
- Stable performance during repeated cycles
- Custom sizing and tolerances for unique furnace layouts
You can choose standard components or request specialized designs.
