Custom Fasteners
Customized Fastener Solutions
We understand that different industries require specialized solutions. Our experienced engineering team collaborates closely with clients to develop tailored fastener designs that optimize performance, durability, and cost-efficiency. With our five-axis machining and CNC capabilities, we can meet the most complex and precise fastening requirements.
TSM Technology specializes in precision-engineered custom fasteners designed to excel where standard solutions fail. We manufacture mission-critical fastening components in premium titanium (Gr.1-Gr.23) and nickel alloys (Inconel®, Hastelloy®, Monel®), utilizing advanced 5-axis CNC machining and precision forging (±0.5mm tolerance) to produce complex, non-standard geometries. Our expertise delivers:
- Unconventional Designs: ACME/UNJ threads, micro-fasteners (0.5mm+) and oversized bolts (M100+)
- Specialized Materials: High-temp alloys (to 1000°C), biocompatible titanium, and EMI-shielding polymers
- Enhanced Performance: Xylan®/DLC coatings for friction control, silver plating for conductivity
Customization Options
▸ Head Styles – Socket, flange, countersunk, or proprietary designs
▸ Drive Types – Torx®, hex, square, or tamper-resistant
▸ Coatings – PTFE for galling prevention, silver for conductivity
▸ Markings – Laser-etched part numbers/barcodes
