  • 1" drive handles high-torque applications
  • Six-point drive grips fastener flats securely
  • Black phosphate finish resists corrosion in wet environments
  • Laser-etched markings simplify size identification quickly
  • Meets ANSI standards for professional reliability

1" Drive 6-Point Socket 1-3/8

This 1" drive standard socket fits 1-3/8" fasteners with a six-point profile that grips the flats of the bolt head. The black phosphate finish resists corrosion in workshop environments. Large laser-etched markings allow quick size identification between SAE and metric sockets. It meets ANSI dimensional standards for impact and hand-tool use.

ANSI Standard Drive Interface

The 1" square drive follows ANSI specifications, so it fits any 1" drive ratchet, breaker bar or impact gun that conforms to the same standard. Six-point geometry distributes torque across the fastener flats rather than the corners, reducing rounding risk on stubborn bolts. The phosphate coating adds a layer of protection but does not change the drive dimensions or the socket's engagement depth.

Compatibility Check Before Purchase

Verify that your drive tools are 1" square drive and rated for the torque you intend to apply. Confirm the fastener you are turning measures exactly 1-3/8" across the flats. Ensure your workspace can accommodate the socket length and the drive tool swing radius. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item

How do I decide which drive size and socket capacity to choose?

This is a single 1 inch drive socket sized at 1-3/8 inch, so you select it when that exact combination matches the fastener you are working on.

What does the 6 point drive design do once the socket is on the bolt?

The 6 point drive contacts the flat sides of the fastener rather than the corners, reducing the chance of rounding off the head under high torque.

What does meeting ANSI standards mean for the socket in everyday use?

It confirms the socket meets recognised dimensional and strength requirements for 1 inch drive impact and hand tools, so it fits standard anvils and handles rated loads.
