Precision That Fits: Custom & Modified Fasteners from SC Fastening Systems
In a perfect world, every part would be readily available, but in the real world of manufacturing, construction, and assembly, that’s not always the case. That’s where SC Fastening Systems comes in—with expert custom and modified part solutions tailored to your exact requirements.
From specialty fasteners to non-standard dimensions and unique finishes, we provide engineered solutions that save you time, improve performance, and help your projects stay on track.

Why Custom and Modified Parts Matter
Sometimes, the fastener you need doesn’t exist—yet. Whether it’s because of extreme environmental conditions, unique load-bearing needs, or limited space constraints, standard hardware can fall short.
Common Scenarios Requiring Custom Solutions:
- Extreme environmental conditions
- Unique load-bearing requirements
- Space constraints
- Legacy equipment compatibility
- Special material requirements
- Aesthetic considerations
- Assembly efficiency needs
- Regulatory compliance
Rather than reengineering your design around a standard part, let us deliver a solution that meets your specs exactly.
What We Can Do
SC Fastening Systems specializes in a broad range of modifications and customizations:
Thread Modifications
- Custom thread pitches or conversions (UNC ↔ UNF ↔ Metric)
- Partial threading or full threading adjustments
- Thread locking patches and pre-applied adhesives
Length Modifications
- Cut-to-length bolts, rods, and studs
- Re-chamfering and re-threading after cut
- Tolerances held to precise specs
Head & Drive Modifications
- Custom head shapes (round, hex, square, pan, truss, etc.)
- Drive type changes (Torx, Phillips, slotted, hex socket, etc.)
- Head trimming or reshaping
Material Changes & Upgrades
- Alternate grades of steel, stainless, brass, nylon, etc.
- Heat-treated parts for higher hardness or strength
- DFARS-compliant or domestic-only sourcing available
Special Coatings & Finishes
- Zinc, yellow zinc, black oxide, phosphate, nickel, and more
- Custom powder coating in any color
- Corrosion-resistant plating options for marine or outdoor use
Stamping & Identification
- Custom stamping, part numbers, or lot identification
- Color-coded parts for easy recognition in assembly
- Laser marking and engraving services
Prototype Support
- One-off or short-run fastener solutions for product development
- Collaborative design assistance and material suggestions
- Speedy turnaround for initial testing or trials
