the right spring.
- Application context — what the part does and what it mates with
- Working envelope — available bore, hole, or shaft dimensions
- Load or deflection target — even rough values help
- Operating environment — temperature, media, cycles, corrosion
- A photo or a sample — of the part you're replacing
If you can ship us a physical sample, we can reverse engineer it, document the geometry, and reproduce it with documented tolerances.
- 1. Print, sketch, or photo
- 2. Quantity (and any release schedule)
- 3. Material preference or environment
- 4. Target lead time
- 5. Application notes (load, fit, mating part)
No drawing? Send a sample. No sample? Send a photo with a ruler.
Materials & Finishes
Common Materials We Run.
Material selection drives load capacity, fatigue life, and corrosion behavior. We help match material and finish to the application and budget.
Music wire (ASTM A228), hard-drawn (A227), oil tempered (A229), chrome silicon (A401), chrome vanadium (A232).
302/304 (A313), 316, 17-7 PH for elevated temperature and corrosive service.
Inconel® X-750, Inconel® 718, Monel®, Hastelloy® for downhole, high-temp, and chemical environments.
Phosphor bronze, beryllium copper, brass — for conductivity and non-magnetic needs.
Passivation, zinc plating, black oxide, powder coat, e-coat, shot peening, and stress relief.
0.012" – 0.625" wire diameter capacity, with round, square, and shaped wire available.

Built for Buyers Who Need Parts That Show Up and Work.
We started Integrity Spring & Fab in 2021 because Houston-area engineers and purchasing teams kept running into the same problem: long lead times, hard-to-reach suppliers, and parts that didn't quite fit. Our promise is the opposite — easy communication, fast response, and parts built for your application.
We can provide FAIR samples when required, and our quality process includes first article inspection and final inspection before parts ship.
