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. The absence of a gap eliminates pin nesting and interlocking. 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.

Spring pins use tension created by compression to lock tight in a hole drilled through two or more components. Coiled pins can be easily identified by the 21 4 coil cross section. 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. 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. A spring loaded alignment pin is fixed on the installation table. 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.

Coiled spring pins were designed for assembly. The absence of a slot eliminates pin nesting and. They are made by forming strips of metal into a spiral shape. 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. Actual diameters are slightly larger than the diameters shown allowing pins to fit tightly when installed. First align the coiled pin up to the hole by hand. 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.

Coiled spring pins are flexible after installation so they absorb shock and vibration better than slotted spring pins. The most common type of spring pin is coiled. The simplest coiled pin installation method is to use a hammer. Three types of coiled pins.

The diameter of the spring pin shrinks as it enters a drilled hole. 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.
