DIN 16903 threaded bushings

Particularly cost-effective due to in-stock standard bushings

Threaded bushings (threaded sleeves, threaded inserts, insert nuts) are often required in the plastic and casting industries. We work according to our customers’ requirements and DIN 16903.

In many cases, our in-stock standard bushings that meet the DIN 16903 requirements can be used instead of individually constructed, expensive varieties. Our customers benefit from our large stock of various types and dimensions, in particular at the product-sampling stage.
