Bowworks™ Thread Stainless Screws with Bronze Eyelets

About the Bowworks™ thread:

This thread was developed by Bowworks™ founder Steve Beckley and has become increasingly popular over the years because of its superior engineering and design. This thread form is designed for repeated lateral transport with steep angles for low friction and polished rounded crests and valleys to avoid cutting into the softer metal of the eyelet during the many decades of use this thread was designed to perform for.

We feel confident that our new bow screws are the right thread form for violin family member screws and eyelets and will still be in service 200 years from now.

The screws are made of stainless steel and the eyelets of bronze. These are tough and durable materials that will last a lifetime. We offer these in finished lengths for Violin and Cello as well as in extra long blanks.

Our violin screws and eyelets are made by Paulus GmbH of Germany. Paulus has been recognized worldwide as the leading manufacturer of violin bow parts and they have maintained this leadership position by setting the standard in quality for generations.
