Coiled Spring Pin Installation

Coiled spring pins were designed for assembly.

Coiled spring pin installation.

This provides the tension necessary to keep. What differentiates a coiled pin. Also known as a spiral spring pin it features a coiled spring that expands when inserted into a hole. They also have higher dynamic load capacities and accommodate wider hole tolerances.

Coiled pins can be easily identifi ed by the 21 4 coil cross section. 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. Spring pins use tension created by compression to lock tight in a hole drilled through two or more components.

Installation flexibility spirolcoiled pin prior to installation slotted pin 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. They also have higher dynamic load capacities and accommodate wider hole tolerances. The most common type of spring pin is coiled. Actual diameters are slightly larger than the diameters shown allowing pins to fit tightly when installed.

Three types of coiled pins. Drive the pin to the desired insertion depth and be careful not to damage the host. 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. Next simply hammer the coiled pin into the hole as if it was a nail.

The absence of a slot eliminates pin nesting and. The diameter of the spring pin shrinks as it enters a drilled hole. The absence of a gap eliminates pin nesting and interlocking. 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.

Coiled pins can be easily identified by the 21 4 coil cross section. A spring loaded alignment pin is fixed on the installation table. They are made by forming strips of metal into a spiral shape. First align the coiled pin up to the hole by hand.

Upon insertion a coiled spring pin will begin to expand to create a strong and secure environment for the joined. Coiled spring pins are flexible after installation so they absorb shock and vibration better than slotted spring pins.
