Fixed Factory Tension
Fixed Factory Tension
Quick look
- Adjustment access: None—pivot is riveted or thread-locked at the factory.1
- Closing feel: Consistent when new, but impossible to tweak if it loosens mid-service.1,2
- Ideal use case: Student kits, backups, or travel tools where simplicity and price outweigh fine-tuning.1
- Care level: Low, but once the pivot drifts you must send it out or replace the shear.1
Why it matters
Fixed factory pivots are set once during assembly and then locked. They show up in cosmetology kits and budget shears because they eliminate user adjustments—and the hardware required to support them. When you simply need a tool that cuts out of the box, this keeps costs down.
How it works
- The pivot is riveted, pinned, or thread-locked so the screw cannot rotate.1
- When tension drifts, a technician has to drill out or rebuild the pivot to restore clamp force.1,2
- Because there’s no access, you can’t fine-tune for different textures or techniques.1
Best for
- Cosmetology schools supplying simple, low-cost shears.1
- Backup kits where multiple stylists grab the same tool occasionally.1
- Travel or backstage kits that take a beating and may be replaced frequently.1
Watch-outs
- Once hair starts folding you can’t fix tension mid-service—plan a replacement shear.1
- Rivets wear faster under heavy use, shortening the tool’s lifespan.1
- Impossible to customise for high-precision work; pros quickly outgrow it.1
Maintenance notes
Clean and oil the pivot like any shear. If blades start folding or gapping, retire the tool or have a sharpener rebuild the pivot—but the repair often costs more than replacing the shear.1,2
