  • TypeSockets
  • 1-inch drive fits heavy-duty impact wrenches
  • 1-1/8 inch SAE opening targets large fasteners
  • 6-point geometry grips flats to reduce rounding
  • Chrome molybdenum steel withstands high torque
  • Black phosphate coating resists corrosion

Socket size and drive

The Westward 21WM20 is a 1-1/8 inch SAE impact socket with a 1 inch drive and 6-point geometry. It is built from chrome molybdenum alloy steel for professional technicians who need a heavy-duty socket for large fasteners. The black phosphate finish resists corrosion in shop environments.

ASME standard and clearance

The socket meets ASME B 107.110 dimensional standards and provides 1 1/32 inch bolt clearance. This specification ensures consistent fit on compatible impact tools and adequate space for bolt heads during high-torque applications. The standardised profile supports repeatable engagement.

Heavy fastener capacity

The 1 inch drive and 6-point design deliver the contact area needed for large industrial and automotive bolts. It handles high-torque impact work on standard SAE hardware within its size range. The socket is not suited for smaller drive tools or metric fasteners outside its 1-1/8 inch specification.

Questions about this item

Will the chrome molybdenum alloy steel socket need replacement after heavy impact use?

The chrome molybdenum alloy steel construction resists wear under impact loads; replace only if the 6-point opening rounds or the black phosphate coating shows deep pitting.

What stops the 1 in drive socket from turning a seized 1-1/8 in bolt continuously?

The 1 1/32 in bolt clearance limits how far the fastener can seat, so the socket bottoms out before full engagement on extra-long studs.

Does the black phosphate finish get hot or slip after all-day impact work?

The phosphate coating reduces glare and corrosion but does not insulate; the socket transmits torque directly and stays cool enough to handle bare-handed.
