The word linchpin is an alteration of the Old English word "lynspin," which people began using in the mid s to mean "axle pin. Since the linchpin is the device that keeps a wheel together, it is no surprise that over time a second definition of the word, meaning an abstract element that keeps a complicated process together, was born.
A person might say, "The wedding planner was the linchpin that made the entire ceremony and reception a success," to indicate how good the person was at keeping track of even the most minute of details. This phrase is in common enough of use for it to appear in major newspaper headlines.

Dowel pins are short cylindrical rods made of either metal, plastic, or wood.
Dowel pins are a simple part that can be removed with basic hand tools. In most cases, the dowel is used as a guide for assembly and will have a protruding end after a part has been disassembled. To remove the dowel pin from a part, securely grasp the protruding end of the pin with a pair of pliers and pull outward. For stubborn dowel pins, a dowel pin puller can be used to effectively extract the pin from its mating part. For applications where the dowel pin is flush to its mating part and its ends are visible on both sides of the mating part, a small punch and hammer can be used for removal.
First, use a punch with a tip slightly smaller in diameter to the pin. Place the tip of the punch on the head of the pin and strike the end of the punch with a hammer.
This will cause the pin to move out the opposite end of the hole it is in. Continue to strike the punch until the pin can be pulled out by hand or with a pair of pliers.
Transcript: Dowel pins come in a variety of shapes and sizes. With the exception of the DIN 7 metric dowel pin, they all measure the same way. The first thing you want to measure is your diameter and then you want to measure the overall length. The overall length on a dowel pin is measured from end to end. And it's that simple to measure a dowel pin. Transcript: What we have here is a DIN 7 metric dowel pin.
The first thing you want to measure on one is your diameter. And then when you measure the length, you're going to measure from edge to edge.
By edge the edge that means you're measuring just to the edges and not the crown of the dowel pin, and it's that simple to measure a DIN 7 dowel pin.

Hair pins, also referred to as hitch hair pins or hairpin cotter pins, are a simple fastener that is primarily used for securing grooved pin applications. To install the hair pin, grasp the looped end of the pin and position the split end in the groove of the shaft, spindle, or pin to be secured. Push the hair pin forward until the first indentions of the pin rests overtop and underneath of the secured part.
To remove, simply grasp the looped end of the hair pin and pull back until the pin is free from its mating part. Hair pins can be measured by three values: the wire diameter, the pins eye diameter, and the overall pin length from end to end. To measure the wire diameter, use a caliper and adjust the jaws until they are touching the outside edges of the wire.
For measuring pin length, open the jaws of the caliper so that one jaw touches closed end of the pin and the other touches the tip of the split end. The last measurement of the hair pin is the eye diameter. The eye diameter is the inside distance between the two wires at their widest point of the second indentation.
To measure the eye diameter, open the caliper jaws so that each jaw touches the inside surface of each wire. For additional information on the different hair pin types G. Huyett offers, check out our online catalog. Huyett is the master distributor and manufacturer of non-threaded fasteners including clevis pins.

The large protruding button at the grip of the pin provides an easily-accessible method to release the detent balls, allowing the pin to be quickly inserted and removed. Ball lock pins are designed with a metal precision ball protruding out on the side of the pin near the end of the pin shaft.
The ball is supported by either a metal spring or rubber cylinder that allows the ball to be depressed into the pin when the pin is forced into a hole. As the ball end of the pin is pushed out the open end of the hole, the ball springs out to lock the pin in place. There are different varieties of ball lock pins, some of which release the ball by use of a button on the handle, and others that rely on force to depress the ball.

As the master distributer and manufacturer of pin and wire form fasteners, we carry one of the largest selections of spring pins in the industry. Spring Pins, sometimes referred to as slotted pins, rolled pins or coiled rolled pins, are hollow, cylindrical tube-style press fit fasteners with chamfered ends. There are several methods that can be used to install a spring pin. Which method is best depends on the environment, be it in field repairs or large production lines.
The simplest method of installing a spring pin is to use a hammer. First, line up the pin to the hole by hand. Next, tap the end of the pin with a hammer driving it into the hole. Special care needs to be made to not damage the pin or its mating part. Another method of installing spring pins is the use of a pin driving chuck with a press or air hammer.
This method works well in small to medium production environments providing better alignment, control, and quicker cycle times. Securely attach the chuck to the air hammer or press and insert the pin into the open end of the driver leaving an exposed end of the pin.
Next, insert the exposed end of the pin to the hole of the mating part and apply force from the air hammer or press until the pin has reached its desired fitment. For large volume installations, spring pins can be installed by an automatic inserter. These automatic inserters are self-contained units with a hopper that vibrates pins into position for installation into a desired part. This process eliminates the need for manual handling of the pin. The inserter does require an operator to monitor the machine and replenishing it with pins as needed.
Proper removal of a spring pin will depend on if the pin is in a blind hole or a through hole. A blind hole is a hole drilled to a specific depth that does not breach the other side of the work piece. A through hole is a hole that goes completely through a work piece. To remove a spring pin from a through hole, use a properly sized roll pin punch.
This will prevent damage to the pin or the mating part. Align the punch to the pin tapping the top of the punch with a hammer driving the pin out the opposite end.
