Ball Lock Pins are ideal for fastening and locating appliances that require positive, secure holding yet have attributes such as the user-friendly, "tool-less" removal convenience provided by ball-lock technology. They operate on a principle of interlocking balls, assuring secure and safe fastening. These locking pins will not release until the button on the handle is depressed. Once the button is depressed, the balls retract into the pin allowing the pin to be removed from the hole. They have a high-strength stiff mechanical stop that prevents the pin from being removed unless the release button on the handle is depressed.

These pins are used for fast clamping and concurrent play-free clamping of slender machinery, predominantly where recurrent clamping and releasing is necessary. A characteristic application is the alignment and fastening of a sheet metal during a welding process. Ball lock pins are also used in airplanes and aerospace industry. Other applications include work piece location, sports equipment, racking or weight stacks. Ball lock pins are offered in three to 12 mm radius pin sizes in carbon or stainless steel and the length can be up to 89mm.

Ball Lock Pins are obtainable in single or double acting mechanisms, in several styles, or in an adjustable grip length version. The Ball Lock Mounting System allows in accurately locating and clamping at the same time, with just the twist of a hex wrench, and is ideal for mounting quick-change fixture plates on a sub plate. Ball lock pins are used for rapid connecting and securing of components or work pieces. By pressing the spring operated push button, the two balls are untied, and by the release the push button, the balls are locked.

Ball Lock Pins are usually used for fastening as well as locating operations. Some other applications include machinery manufacturing, nut and bolt replacement, mining machinery, automobile industry, agricultural machinery and electronics.
