Threaded Rods & Studs Types

Equal thread length rods and studs are double-ended threaded studs that have an equal number of threads on each side and a smooth body in-between. Threads can be right-handed on one end and left-handed on the other. The studs may also have hollow centers to allow venting, or they may have female threads on the inside of the stud.

Fully threaded rods and studs, are threaded along their entire length with either right- or left-handed threads. They are useful where quick assembly and disassembly are needed. This style of fastener is sometimes called an "All Thread" rod.

Press-in captive studs, also known as self-clinching studs, are placed into a punched or drilled hole and squeezed into place with a standard press. The squeezing action embeds the head of the stud into the panel, creating a flush-head assembly and securely locking the stud into the panel with high torque-out and push-out resistances.

Unequal thread length studs are double-ended thread studs that have a different number of threads on each end and a smooth body in-between. There is a self-locking version of these studs that have threads suitable for a nut on one end and threads for a tapped hole on the other end.
