Composite Screw Contacts

In many applications, Deringer composite screw contacts offer greater economy through minimal use of costly precious metals, using the contact for more than one purpose, choices of designs and materials and a reliable bond.

Composite screw contacts are used in applications that require one or more of the following:

1. quick, easy adjustment or replacement in the field,
2. in-manufacture or field calibration,
3. where the screw economically serves as both the electrical contact and fastener.

These contacts are normally made by fusing or brazing, depending upon size, materials, electrical requirements and cost. When fused, backing is usually nickel-plated steel because of its strength, low electrical resistance through proper bonding and excellent resistance to corrosion.

Since such composite screw contacts can serve so many functions, the size charts list only several standard or typical sizes. When you have an application that may involve a composite screw contact, Deringer engineers will work with you to determine that particular design, combination of materials and manufacturing process best suited and most economical for your specific application.
