Coiled Spring Pin Installation

Coiled spring pins were designed for assembly.

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 absence of a gap eliminates pin nesting and interlocking. The most common type of spring pin is coiled. What differentiates a coiled pin.

They are made by forming strips of metal into a spiral shape. Coiled pins can be easily identifi ed by the 21 4 coil cross section. Drive the pin to the desired insertion depth and be careful not to damage the host. Coiled pins can be easily identified by the 21 4 coil cross section.

Also known as a spiral spring pin it features a coiled spring that expands when inserted into a hole. Compared to other pins the square ends concentric chamfers and lower insertion forces ease installation. First align the coiled pin up to the hole by hand. 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.

Three types of coiled pins.

They also have higher dynamic load capacities and accommodate wider hole tolerances. Before installation the diameter of a spring pin measures slightly larger than a drilled hole. Coiled spring pins are flexible after installation so they absorb shock and vibration better than slotted spring pins. This provides the tension necessary to keep.

Spring pins use tension created by compression to lock tight in a hole drilled through two or more components. A spring loaded alignment pin is fixed on the installation table. Actual diameters are slightly larger than the diameters shown allowing pins to fit tightly when installed. The simplest coiled pin installation method is to use a hammer.

The diameter of the spring pin shrinks as it enters a drilled hole. Next simply hammer the coiled pin into the hole as if it was a nail.
