Choose the Correct Fit
Match the exact socket model to the manufacturer’s retaining-ring chart. Confirm the socket body and drive, not just its fastener opening.
Use this ring for the published 9/16–1 in SAE socket selection. Do not assume it fits a larger socket because the drive size is the same.
Installation & Care
Align and seat the retention features as the socket and impact-wrench instructions direct. Check secure attachment before operation.
Inspect the rubber for cuts, cracking or stretching. Replace a damaged ring and never use it to lift, support or tether a load.

Important Product Questions
Is this a load-bearing safety tether?
No. The ring supplies socket retention only and must not support a suspended tool, socket or workpiece. Use approved lifting or tethering equipment when that is required.
Will it fit every socket with the same drive?
No. Socket-body dimensions and retention geometry also matter. Check the exact socket model against Milwaukee’s retaining-ring chart rather than choosing by drive alone.
Can I use it on another brand’s socket?
The published fit applies to matching SHOCKWAVE Impact Duty sockets. Confirm another manufacturer’s required retention system before combining parts; similar drive dimensions do not establish compatibility.
