Electrical Connectors Information - GlobalSpec
Card edge connectors (also called edge card connectors) are embedded devices that mate with the edges of single-sided or double-sided printed circuit boards (PCBs) in order to provide an external electrical connection.
Globe Valves Selection Guide: Types, Features, Applications
Design Tip: Take care to not screw the valve shaft too far because there is a possibility it could damage the seating surface. For quick-acting globe stop valves, the stem is placed so the disk closes in the same direction as the fluid flow. Closing the valve is impeded by the kinetic energy of the media but opening is faster and easier.
Washers Selection Guide: Types, Features, Applications - GlobalSpec
Other Common Types : Flat washers, also referred to as Type A plain washers, are thin, flat, and circular general-purpose washers with a centrally located hole. Standardized flat washers may be designed by the use of imperial or metric dimensions. Standard imperial washers include SAE washers, for use with fine threaded nuts and bolts, and USS flat washers, for use with coarse threaded bolts ...
Hydraulic Fittings Selection Guide: Types, Features, Applications ...
Image Credit: Carr Lane Manufacturing. Bite-type fittings are compressive fittings with a sharpened ferrule that "bites" the vessel when compressed and provides the seal. Bite-type fittings, like standard compressive fittings, require no special tools to assemble, but provide a stronger, higher pressure connection.

Screws Selection Guide: Types, Features, Applications - GlobalSpec
Screw Features. Several integral features are available in screws, which increase their versatility. Breakaway screws have a hollowed shank that greatly reduces their shear load. This is useful in mechanical components which may experience overload, or in accident regulation.
Impellers Selection Guide: Types, Features, Applications - GlobalSpec
Impellers (also spelled impellors or impellars) are rotating devices designed to alter the flow and/or pressure of liquids, gases, and vapors.Impellers consist of various vanes — often blade-shaped — arranged around a short central shaft. When the shaft and vanes rotate, they suck in fluids or gases and impel them out the other side.
