Twist Locks
Twist locks are push-fit PCB supports and panel spacers designed to provide secure fixed-height stand-off mounting without the need for screws or tools. They are commonly used to support printed circuit boards and panels inside enclosures, holding components at a consistent distance from a chassis while providing insulated and vibration-resistant fixing.
What are twist locks?
Twist locks feature a round disc base that sits flush against a panel or chassis, a long body that sets the stand-off height, and a shaped locking head designed to locate and retain a PCB or panel edge once the part is installed. The fixing is pushed into a mounting hole, where it compresses for insertion and then locks into place.
Many twist lock designs are intended for non-round mounting holes and use a quarter-turn action after insertion to lock securely. Arrow head style shanks provide an extended panel thickness range and improved retention. Once fitted, the head positively supports the board or panel while resisting vibration and accidental release.
Twist locks are also known as snap-in PCB supports, locking board mounts, push-fit PCB spacers or nylon panel support pillars. These terms are commonly used across electronics and industrial fastening ranges to describe tool-free PCB and panel support fasteners.
