Why this one
12-point engagement
The internal geometry engages the hex head at multiple rotational positions, so you can start turning even when obstructions limit your ratchet swing.
Low-profile 1/4 inch drive
The compact quarter inch drive keeps the profile low for work in congested engine bays, electrical cabinets and equipment housings.
Regular depth
A regular-depth socket that works with a short-handle ratchet for control, or with an extension bar when depth is the challenge.
Sizes 4 to 13 mm
Sold individually in sizes from 4 to 13 mm, so you can restock a worn favorite without buying duplicates.
Read the full description
Sitting toward the top of the 1/4 inch drive capacity, this Teng Tools 13 mm piece gives you the precision to work metric fasteners without jumping to a heavier drive size. The internal geometry engages the hex head at multiple rotational positions, so you can start turning even when obstructions limit your ratchet swing.
The compact quarter inch drive keeps the overall profile low enough for work inside congested engine bays, electrical cabinets, and equipment housings. Pair it with a short-handle ratchet for maximum control, or add an extension bar when depth is the challenge rather than width.
Sold individually, this piece is perfect for restocking a worn-out favorite, plugging a gap in an inherited tray, or keeping a dedicated size at a workstation that sees the same fastener day after day. No need to buy duplicates of sizes you already own.
Professional automotive techs, industrial maintenance crews, and dedicated home mechanics all benefit from metric coverage that is complete down to the last size. Drop this 13 mm piece into your Teng Tools layout and know that the next job will not stall for want of the right tool in the right place.
