The plain finish 18-8 stainless steel headless spring anchor with hex jam nut has a single-grooved body and a threaded end to connect an extension spring to a component, and is made in USA. The included hex jam nut installs with a wrench to secure the anchor. The 18-8 stainless steel material provides strength and offers good corrosion resistance in many environments. The material may be slightly magnetic.
Spring anchors are fasteners that connect extension springs to moving or stationary components in a system. Also known as spring connector studs, they have a head or other unthreaded portion on one end that holds the extension spring and a threaded body on the other end that connects the spring to the component. Spring anchors may have a drilled hole in their head to hold the spring, or they may have one or more grooves on their body for the spring to wrap around.
