3/8" Drive Metric Socket Bit Set 8pcs
The Westward 54TM66 is an eight-piece metric socket bit set built for mechanics and technicians who need hex-drive fasteners in a compact drive size. Alloy steel construction and a chrome finish provide durability for professional workshop use. The set covers common metric sizes from 3 mm to 10 mm.
Drive Size 3/8 In. Female Square
The single specification that determines fit is the 3/8 inch female square drive, which accepts standard 3/8 inch ratchets and extensions. Each bit features a hex tip matching the included 3, 4, 5, 6, 7, 8, 9, and 10 mm sockets. ASME B18.3.2M-1979 compliance confirms dimensional accuracy.
Sustained Workshop Use
Alloy steel bits resist rounding when high torque is applied repeatedly across multiple fasteners. The chrome finish protects against corrosion during daily exposure to fluids and humidity. Overall length of 4-53/64 inches gives sufficient reach without excessive leverage that could damage smaller hex tips.

Questions about this item
What does the 3/8" drive size mean when I'm using these sockets with a ratchet?
The 3/8" female square drive fits standard 3/8" ratchets and extensions, letting you apply torque to the 3–10mm hex bits included in the set.
Which standard governs the hex tip dimensions on these bits?
The hex tips follow ASME B18.3.2M-1979, so they match metric fastener tolerances for a secure fit on 3mm through 10mm socket head cap screws.
How much space do I need in my tool drawer for the longest bit in this set?
The longest piece measures 4-53/64 inches overall, so allow at least that depth plus clearance for the rail or tray you store them on.
