Product Description
ARS-G515-ISW - Internal Tooth Star Washer for UHF / SO-239 and Type N Connectors
The American Radio Supply ARS-G515-ISW is a precision Internal Tooth Star Lock Washer manufactured from 410 stainless steel and designed for use with standard UHF (SO-239) and Type N (RFN) female connectors. It provides increased locking tension and resistance to loosening while helping establish reliable metal-to-metal contact between the connector and mounting surface.
The internal serrated teeth grip the mating surface as the assembly is tightened, helping prevent the connector from rotating or loosening due to vibration. The smooth finished exterior edge makes an internal-tooth washer particularly useful where a cleaner appearance is preferred over an external-tooth lock washer.
410 Stainless Steel
The ARS-G515-ISW is manufactured from 410 stainless steel, a martensitic stainless steel commonly selected when greater hardness and strength are desired.
410 stainless steel offers resistance to:
- Good for dry atmospheric conditions
- Fresh water, stream and hot gases
- Mild alkaline and acids
410 stainless steel is magnetic, making this washer suitable for applications where a magnetic stainless-steel material is preferred.

Internal Tooth Lock Washer Design
The inward-facing teeth engage the mating surface when the connector assembly is tightened. This adds locking tension and increases resistance to loosening.
Internal-tooth lock washers are particularly useful when:
- A secure connector installation is required
- Vibration resistance is important
- The washer is installed beneath a fastener or connector hardware
- A smooth, finished exterior edge is preferred
- Reliable mechanical contact and bonding are desired
