Frequently Asked Questions

How does this compare to standard impact sockets without wheel protection?

Standard impact sockets lack the protective nylon sleeves that prevent scratches on alloy wheels. This ESCO set's thin wall design also provides better access to recessed lug nuts, while the color-coding system speeds up socket selection in busy shop environments compared to unmarked standard sockets.

Will these sockets work with my 1/2" impact wrench?

Yes, these sockets are specifically designed for 1/2" drive impact tools. The CR-MO alloy steel construction handles high-torque applications without damage, making them perfect for pneumatic and electric impact wrenches up to professional shop specifications.

What makes the thin wall design better for automotive work?

Thin wall sockets have reduced outer diameter while maintaining strength, allowing access to lug nuts in tight wheel wells and recessed mounting points. This is especially important on modern vehicles with complex wheel designs and limited clearance around brake components.

Are replacement protective sleeves available if they wear out?

While the nylon sleeves are durable and designed for extended use, ESCO does offer replacement parts for their professional tool lines. Contact your tool supplier for availability of replacement sleeves for model 40306.

Warranty & Shipping

This ESCO impact socket set comes with a limited lifetime warranty on the sockets themselves, covering defects in materials and workmanship under normal professional use. The warranty demonstrates ESCO's confidence in their CR-MO alloy steel construction and professional-grade manufacturing standards.
