Termilock Terminal Screws Applications
EAD-69 Terminal
Screws Line

Terminal screws are electrical screws with captive self-lifting spring clamps. The formed clamp allows for multiple wire configurations and prevents the wire from loosening under fatigue or being pulled out. This is a critical safety feature of terminal screws; without which the contact would heat up and eventually lead to failure. Eisen designs and manufactures terminal screws for UL and IEC Compliant applications. Eisen’s Termilock™ are the gold standard in terminal screws using captive washers. These products are uniquely engineered with tighter tolerances and made using custom raw materials on special purpose machines. All this effort allows us to make the highest performing terminal screws in high volumes. Electrical manufacturers all over the world use Eisen’s terminal screws for motor contactors, terminal blocks, relays, timers, and grounding contacts. Eisen’s Termilock™ terminal screws with captive washers are offered in alloy steels, brass, and stainless steel.

Terminal Screws with Captive Washers

In today’s more sophisticated world of electrical distribution, consistently reliable electrical contacts are essential to product performance and safety. Our design and manufacturing capabilities provide virtually any type of stamped terminations pre-assembled to a wide range of screws. Even multiple washer assemblies are available to meet special termination needs. These washers can be flat and smooth or dished and ribbed. Dished or arched washers increase torque absorption, clamp load, and allow for single/dual wire terminations. Furthermore a complete capability to engineer and develop a wide variety of Saddle Clamp Sems is also available to assure positive wire retention. 

UL and IEC Compliant

Eisen is an American company that designs and manufactures Termilock™ terminal screws. Termilock ™ are designed to withstand both UL 486 and IEC 60999 torque, secureness, and pullout tests. These terminal screws are available in all typical head styles and recesses, such as cheese heads, combination phillips/slotted, milled slots, etc. Self-threading terminal screws are available for chip-free forming of threads in untapped contacts. All terminal screws are available in steel and stainless steel.

Jam Proof

In some products our specialized machines and tools manufacture the terminal screws to very tight tolerance. This helps prevent jamming of screw threads by separating the clamping plate from the threads. Additional features lift the clamping plate straight up when the screw is loosened for a smooth release of the wire.
