Coiled Spring Pin Installation

Coiled spring pins are flexible after installation so they absorb shock and vibration better than slotted spring pins.

Coiled spring pin installation.

Prior to installation all spring pins have the common characteristic of a pin diameter larger than the hole diameter into which the pin is installed. The use of a spring loaded alignment pin is recommended for assemblies with through holes to ensure alignment is maintained between the pin and the holes of the assembly components throughout the entire installation process. They are made by forming strips of metal into a spiral shape. Before installation the diameter of a spring pin measures slightly larger than a drilled hole.

Actual diameters are slightly larger than the diameters shown allowing pins to fit tightly when installed. Next simply hammer the coiled pin into the hole as if it was a nail. They also have higher dynamic load capacities and accommodate wider hole tolerances. Coiled spring pins were designed for assembly.

The absence of a gap eliminates pin nesting and interlocking. What differentiates a coiled pin. Coiled pins can be easily identifi ed by the 21 4 coil cross section. Three types of coiled pins.

Additionally coiled pins can accommodate wider hole tolerances better than any other pin type because they compress during installation and conform to the shape of the hole. The simplest coiled pin installation method is to use a hammer. Upon insertion a coiled spring pin will begin to expand to create a strong and secure environment for the joined. Coiled pins can be easily identified by the 21 4 coil cross section.

Compared to other pins the square ends concentric chamfers and lower insertion forces ease installation. Drive the pin to the desired insertion depth and be careful not to damage the host. A spring loaded alignment pin is fixed on the installation table. Also known as a spiral spring pin it features a coiled spring that expands when inserted into a hole.

The most common type of spring pin is coiled. This provides the tension necessary to keep. The diameter of the spring pin shrinks as it enters a drilled hole. They also have higher dynamic load capacities and accommodate wider hole tolerances.

The absence of a slot eliminates pin nesting and. Coiled spring pin assortments coiled spring pins are flexible after installation so they absorb shock and vibration better than slotted spring pins.
