Product Description

Zirconia Ceramic Screw and Bolts

Typically, ceramic screws are used in low-stress & high temperature conditions. These conditions are most commonly found in electronic equipment, where ceramic screws are particularly attractive due to their lack of electrical conductivity. Another benefit of ceramic screws over polymer based ones are that they have much higher and longer lasting performance due to their ability to withstand sustained heat cycling.

 

Supply in M2x5, M3x10 and M4x10 screws with nuts, customized size is acceptable.We recommend to use the screws only together with the supplied nuts. The usage with metallic threads might not fit as the ceramic parts are manufactured in moulds and reach their final dimension after sintering. Hence they have other tolerances than metallic threads.
