Quality is the true measure of productivity.
(Peter F. Drucker)
We have acquired Licensed Japanese Industrial Standards, a proof of business confidence and authorization of ISO9001-2000.

Soon after establishing the company, we adopted a system to develop a factory with Licensed Japanese Industrial Standards that keeps providing the continuing high quality JIS products.　We obtained "Written permission of Licensed Japanese Industrial Standards" for "JIS E 1108 Track spike" in October in 1952.　Shortly after that, we obtained the written permission of the Licensed Japanese Industrial Standards for "Hex. Bolt" and "Track bolt".　Including the screw spike, we obtained the written permission of the Licensed Japanese Industrial Standards and the authorization of Licensed Japanese Industrial Standards for 4 items.

Permission and authorization of representation are footholds of quiet self-pride for the quality of our products and our productivity, as well as proof of customer reliance to us.

We have adopted many inspection facilities for the inspection of mechanical property. We changed the Tensil Testing Machine from 50 tons kgf to 100 tonskgf. The Bolt Torque Testing Machine for the measurement of axial tension, and an enlargement projector, for the measurement of shape were adopted to verify the quality stability with our best efforts at any time.

To ensure the quality stability further more, we obtained the authorization of 《ISO9002》 in 2002 in addition to JIS, and changed it to 《ISO9001》 in 2003.

"Tohoku bolt MGF. Co., Ltd." will positively keep improving and developing to respond to customer reliance without a break.

A veteran's experiences and wisdom that draw out the potentiality of the existing facilities.
A young person's courage and quest to challenge the innovativeness.
Fusion between low technology and high technology,Collaboration between dissemination and creation.
Pursuit, discovery and flight...
Could we be adaptable to needs for greater diversity and sophistication?
TOHOKU NEDI supports a greater world by exploring a more exquisite world.
