Selection Criteria and Comparisons
How to Choose
Match drive size to your impact tool, confirm the fastener size at 39 mm, and choose shallow length when clearance is tight. Compared to generic sockets, this Tekton offers dual size markings, full-length well geometry, and Cr-Mo impact steel.
Alternatives
Standard chrome hand sockets lack impact-rated Cr-Mo construction; deep sockets add length you may not need. The SID22139 hits the affordable value point for a brand-name 39 mm impact socket.
Use Cases
- Heavy truck axle and wheel fastening
- Agricultural and construction equipment service
- Industrial maintenance on large hex hardware
