These stainless steel anchor studs offer excellent corrosion resistance. The head swivels 360° so the spring stays straight and properly coiled. Attach an extension spring to a stud and then thread the stud into your part for a secure connection. To make tightening easier, anchors have a hex socket on the bottom and wrench flats at the top of the threads.

Create an automated system to test continuity in circuit boards. Combine these spring-loaded test probes with Spring Test Probe Sockets that are permanently attached to testing fixtures. Test probes and sockets are sold separately.
30° spear probes test flat and female surfaces without marring. 90° cup probes guide protruding objects, such as terminals and pins. Waffle probes have many points of contact to test flat surfaces as well as terminals and pins without marring.
When installing test probes and sockets, adhere to the "minimum spacing between probe centers" to maximize testing points while preventing probes from interfering with each other. Spring test probes will produce optimal results when your system is set up to achieve the working stroke length. Initial spring force is the force required to start compressing the probe; maximum spring force is the force applied at the working stroke length.
