SATA ST21106 1/4" Drive Torx Bit Socket T30

It features a precision-fit tip, large stamped size markings for quick identification, heat-treated construction for durability, and S2 steel insert bits for strength and longevity.

The socket is made from chrome vanadium steel with a chrome-plated finish for corrosion resistance, and it uses S2 steel insert bits to maximize strength and durability for demanding tasks.

The 1/4" drive indicates the square fitting size that mates with most ratchets and extensions in that standard, enabling compact use in tight spaces.

The precision-machined tip provides a snug grip on Torx screws, reducing slippage, protecting fasteners, and minimizing wear on both the bit and screw during tightening and loosening.

It's versatile for automotive work, electronics assembly, and general mechanical tasks that involve Torx T30 fasteners.

Attach the socket to a compatible 1/4" drive ratchet or extension, ensure a secure, fully seated connection, and apply steady, even torque to avoid slipping or over-torquing.

Wipe it clean after use and keep it dry. Store in its case or a organized toolbox to prevent corrosion. Avoid harsh solvents that could affect chrome plating.

Both are 1/4" drive Torx bit sockets from SATA, but ST21104 is the T25 size while ST21106 is T30. If you need the smaller fastener size, choose T25; for larger Torx fasteners, T30 is the match. See: https://fepy.com/products/sata-st21104-1-4-drive-torx-bit-socket-t25

ST21107 covers the T27 size, which sits between T25 and T30. If you’re working with T27 fasteners, this is the better fit; for T30 applications, ST21106 is the appropriate choice. See: https://fepy.com/products/sata-st21107-1-4-drive-torx-bit-socket-t27

Look for the large stamped size on the socket—this model clearly shows T30, making it easy to identify at a glance and avoid mix-ups in a busy toolbox.
