Key Features of Wave Tooth Spring Roll Pins
Slotted Spring Structure
The longitudinal slot allows the pin body to compress during installation and recover radially after insertion. This flexibility helps the pin maintain contact with the mating hole.
Tooth Profile for Retention
The formed tooth profile provides localized engagement with the hole surface, supporting pin retention under suitable assembly conditions. Performance depends on hole dimensions, material properties, and installation quality.
Heavy-Duty and Light-Duty Configurations
Available configurations follow Q/PES 002-2026 for heavy-duty pins and Q/PES 003-2026 for light-duty pins. Buyers can select the appropriate type according to dimensional requirements and assembly conditions.
Multiple Material Options
Depending on the applicable specification, material options include carbon spring steel, alloy spring steel, and stainless steel. Material grade and hardness should be selected according to the required mechanical performance and operating environment.

FAQ
What is the difference between a Saw Toothed Pins and a standard slotted spring pin?
A Saw Toothed Pins incorporates a formed tooth profile that changes how the pin contacts the mating hole. A standard slotted spring pin relies primarily on radial spring pressure. The appropriate design depends on the required retention characteristics and assembly configuration.
How should the mating hole be designed for a Saw Toothed Pins?
The hole diameter, tolerance, roundness, and surface condition should follow the requirements specified for the selected pin. Excessive clearance or an undersized hole may affect insertion force and retention, so compatibility should be verified before production assembly.
Can tooth spring roll pins be used in vibrating equipment?
They may be suitable for certain vibrating assemblies, depending on the pin design, joint loading, and operating conditions. Engineers should evaluate vibration intensity, cyclic loads, hole wear, and the consequences of pin movement before selecting a fastening method.
