Fasteners

Fasteners (aluminum or insulating securing units, double or triple nuts, screws, washers…)

Thanks to our experience in high currents and numerous laboratory tests, we have developed certain parts to optimize the quality of electrical contact. Indeed, the materials used are sometimes very soft, such as aluminum 1050A, and special care must be taken to ensure good contact over time and not deform the contact surfaces.

Support washers: to guarantee uniform contact pressure, we use non-standard diameter washers.

Spring washers: in the field of power connection, the spring washer must work in compression and expansion. We have developed our washer that works in its optimal elastic range; the steel and surface treatment have been determined to guarantee the maintenance of the spring effect over time and galvanic compatibility.

Double/triple nuts allow easy tightening of the connections by one person instead of two. Since tightening is often done in multiple steps, and the tightening control must also be carried out on each screw, time savings are significant.

Additionally, the shape of the double/triple nut ensures uniform tightening pressure. The material of the copper-aluminum double/triple nut also guarantees low friction and prevents seizing.
