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.

A spring loaded alignment pin is fixed on the installation table. The absence of a gap eliminates pin nesting and interlocking. They are made by forming strips of metal into a spiral shape. The most common type of spring pin is coiled.

What differentiates a coiled pin. The simplest coiled pin installation method is to use a hammer. Compared to other pins the square ends concentric chamfers and lower insertion forces ease 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. This provides the tension necessary to keep. Coiled spring pins were designed for assembly. Coiled spring pin assortments coiled spring pins are flexible after installation so they absorb shock and vibration better than slotted spring pins.

Before installation the diameter of a spring pin measures slightly larger than a drilled hole. Three types of coiled pins. Spring pins use tension created by compression to lock tight in a hole drilled through two or more components. The absence of a slot eliminates pin nesting and.

Next simply hammer the coiled pin into the hole as if it was a nail. The diameter of the spring pin shrinks as it enters a drilled hole. Coiled pins can be easily identifi ed by the 21 4 coil cross section. Actual diameters are slightly larger than the diameters shown allowing pins to fit tightly when installed.

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. Upon insertion a coiled spring pin will begin to expand to create a strong and secure environment for the joined.

Drive the pin to the desired insertion depth and be careful not to damage the host. First align the coiled pin up to the hole by hand.
