Coiled Spring Pin Installation

What differentiates a coiled pin.

Coiled spring pin installation.

Coiled pins can be easily identifi ed by the 21 4 coil cross section. This provides the tension necessary to keep. 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 diameter of the spring pin shrinks as it enters a drilled hole.

They also have higher dynamic load capacities and accommodate wider hole tolerances. Coiled pins can be easily identified by the 21 4 coil cross section. 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. Upon insertion a coiled spring pin will begin to expand to create a strong and secure environment for the joined.

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. Coiled spring pins were designed for assembly.

The absence of a slot eliminates pin nesting and. First align the coiled pin up to the hole by hand. Three types of coiled pins. The absence of a gap eliminates pin nesting and interlocking.

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. The simplest coiled pin installation method is to use a hammer. The most common type of spring pin is coiled. Compared to other pins the square ends concentric chamfers and lower insertion forces ease installation.

Coiled spring pins are flexible after installation so they absorb shock and vibration better than slotted spring pins. They are made by forming strips of metal into a spiral shape. A spring loaded alignment pin is fixed on the installation table. Spring pins use tension created by compression to lock tight in a hole drilled through two or more components.

Drive the pin to the desired insertion depth and be careful not to damage the host. Also known as a spiral spring pin it features a coiled spring that expands when inserted into a hole.
