Cross-Over Genius Inventing
Ultra S.S. Anti-Corrosion Screw
Mr. Hsiang Wu, president of Best Quality
Wire, is one of the classic Taiwanese figures breaking industry boundaries
for innovation. He is a Taiwanese wire rod maker by profession, with a strong
curiosity to learn about screws. He asked for advice from a fastener friend, who
was touched by him, supported his creative concept and allowed him to learnabout screw manufacturing. The opportunity led him to understand the pain
points of certain screw products during production. In his decade-long journeyof learning, he had moments of being looked down upon, but always believed
he could contribute to the fastener industry. Eventually he was able to create apatented revolutionary technique called “Forming Method for Stainless SteelScrew Capable of Direct Drilling and Fastening”.
Hsiang Wu found bi-metal screw production requires multiple procedures andis lower in speed and output capacity compared to stainless steel screw production.
The pain point, he discovered, is the inability to form bi-metal screws in one piece.
His new patent was born to tackle this pain point. Using his forming method, hesuccessfully manufactured “Ultra S.S. Anti-Corrosion Screw”— a new productfrom Best Quality Wire.

Patented Technique—
Rust-Prevention Level Above S.S. 304/316 & Replacing
Complicated Bi-metal Screw Procedures
The biggest feature of this stainless steel screw is the ability to be formed in asingle process, not requiring dual-material welding, turning, threading, cleaning,surface treatment and other processes pertaining to bi-metal screws. Comparedwith bi-metal screws, “Ultra S.S. Anti-Corrosion Screw” has surface hardness up
to 550HV, core hardness over 520HV, tension coefficient at 173kgf/mm2, resisting
corrosion for over 3,000 hours and acid rain for over 50 cycles. The screw itself isrust proof and corrosion resistant, not requiring surface treatment.
With this patent, “Ultra S.S. Anti-Corrosion Screw” can replace bi-metalscrews, with an added value of significant cost production reduction for clients,
faster production, higher production volume, shorter lead time, energy saving andlower carbon emission. “I can guarantee the use of this screw for 20 to 30 years
without rust. I hope to extend its use to yacht, wind/solar power, construction andautomobiles. With global inflation and EU carbon tax pressing on, I hope thisscrew can help clients face the carbon tax challenge and be more cost-competitive,
thereby contributing to environmental protection”, said the president.

Fastener World no.202/2023 惠達雜誌This technique has earned patents in Taiwan,
Europe and the U.S. “Ultra S.S. Anti-Corrosion
Screw” has of f icia lly appea red at Ta iwa nInternational Fastener Show this year, gaining
many inquiries and acclaims from domestic
and overseas buyers. The potential is not to beoverlooked.

3 Pillars to Go Along the Carbon
Reduction Era
The president has been long focused on
environmental protection. He previously invented
the “Auto Sludge Discharging & Oil Recycling
Machine” which separates oil and water sludge
from production line. Following “Ultra S.S.
Anti-Corrosion Screw”, his next step is to focus
on the revolutionary optimization of wire rod
ma nufact u r ing process. He will develop aproduction line that integrates wire drawing,pickling, roughing and finishing, and phosphoricacid coating into a single process. In other words,
his future production line will be able to form
wire rods in one process. Additionally, he has been
preparing for carbon inventory since five years
ago. An inventor, Hsiang Wu has the new patentbolstering Green Manufacturing, the “Ultra S.S.
Anti-Corrosion Screw”, and a future optimized
manufacturing processes, altogether ready to face
the carbon reduction era!
