Products | Standoffs

Overview

Standoffs are a versatile family of fasteners designed to hold a fixed gap between two panels via some static attachment. They are made from rigid bar stock in round or hex profiles based on the application requirements. A standoff with a male attachment has external threads like a screw or bolt, while a female attachment has internal threads like a nut. Some SNAP-TOP® or KEYHOLE® standoffs can forego threads in order to solve specific application problems.

Application

A common application for standoffs is the mounting of PC Boards to manage potential short circuits. The housing of a gaming PC is essentially a large, current-carrying metal box; raising the motherboard away from the housing helps eliminate the risk of a short circuit between components.

Alternative Solutions

Some prebuilt PCs have integrated standoffs or ‘nubs’ designed into the housing to minimize the number of loose parts. While this may be cost effective for a mass-produced assembly, it limits the opportunity for customization. For custom PCs, it wouldn’t be reasonable to develop several cases with standoff nubs in every possible location for different components. Fasteners would allow for more freedom of placement.

Common Attachment Technologies

On the manufacturing side, if a company has several models of prebuilt PCs, greater placement flexibility can be achieved by using self clinching standoffs. They can decrease tooling or assembly costs and facilitate production modifications for new designs. Broaching or surface mounted (SMT) standoffs are used for spacing an additional panel or component above a circuit board in a PCB-to-PCB junction.
