Import Source Development

We've improved fastener plants in Taiwan and Japan, and in 2002 we set up Asian headquarters in Shanghai to do more work in China. If you're not receiving conforming products, we'll determine what problems exist and in a tactful manner eliminate them. Additionally, we can evaluate new sources, assist with contract wording for quality protection, and facilitate importing products direct to you. Further, we can be very valuable regarding joint ventures or manufacturing agreements.
