Spring Pin (for General Purposes)

Spring Pin (for General Purposes)【1-1,000 Pieces Per Package】

OCHIAI

[Features]
· Cylindrically coiled thin plate with a slit. When inserted (by press fit) into a hole with a diameter slightly smaller than that of its outer diameter, the pin applies internal pressure to the hole (force due to its expansion), preventing it from dropping out from the hole.
· This hollow pin contributes to weight reduction when compared with solid pins.
· Used for positioning, turn prevention, and retention, etc.
· Used for simple fastening and positioning, etc.
· Its grip prevents it from dropping out from its mating hole.
· When it is necessary to increase the shear load, use a double-pin structure. (The load is made by adding the shear load on the outer and inner pins.)
