Direct-mounting screws and bases
Description
Direct mounting of component holders to breadboards or tables gives very compact and rigid assemblies, and is especially useful for our stock-size lens holders and other items with standardised axis heights, allowing different items to be mounted coaxially. For standard axis heights, and packers to make up differences see Posts, thread adaptors and packers.
The simplest method of direct mounting is to use the special screws listed, which are inserted from the underside of a breadboard or platform. Part of the screw shank is unthreaded, allowing it to turn freely once inserted.
Direct-mounting bases are more versatile and convenient, not requiring access to the underside of the baseboard, and can be used on optical tables, stages, rod carriers etc. as well as breadboards. They are in two parts, having a removable insert which screws into the component holder. The insert rotates freely in the lower part until clamped by a thumbscrew, which also holds the component positively down in position. Components can therefore be quickly removed and replaced in the same position.
The simple circular bases hold a component directly over a hole in the breadboard etc.; the slotted bases allow freedom of positioning, and are narrow enough to be placed in adjacent holes (25mm centres) if required.
The bases listed accommodate the common American Unified threads as well as metric threads used in our own equipment.
