STANLEY STMT71652 123-Piece Socket Set

The STMT71652 covers all three drive sizes — visible in the product images alongside SAE and metric sockets in both shallow and deep lengths. Metric range 3–14 mm confirmed from labeled tray images; SAE range covers 5/16 in. and up with larger sizes visible. The 10 mm metric is confirmed from images 3 and 4 with size labels clearly visible in the tray. Beyond sockets, the 123-piece count includes two ratchets, extension bars, a hex key set, screwdriver handle, and a bit set — approximately 55–65 actual sockets in the tray. Stanley's Max-Drive design markets a 6-point-style fastener engagement; the profile visible in images is consistent with 6-point construction. 4.7★ across 576 reviews with no rounding complaints identified. Hand-ratchet use only — not rated for impact drivers.

The right pick for a home mechanic who wants a single kit covering the full drive-size range — oil changes, brake jobs, engine-bay electrical work, and wheel and suspension fasteners. All three drive sizes in one case eliminates the need for supplemental sets, and the confirmed 10 mm metric presence covers the most commonly needed fastener. Skip if the set needs to be sourced new — STMT71652 is no longer listed on Stanley's website and is out of stock on Amazon as of 2026-05-19; availability is limited to used or third-party marketplace inventory. Also skip if you plan to use an impact wrench; these are Cr-V hand-rated sockets only, and impact use risks shattering.

No chemical exposure pathway — chrome-vanadium steel hand tool with no SDS. Chrome-vanadium steel is rated for hand-ratchet and breaker-bar use — not for impact wrenches; impact-rated sockets use a different alloy (chrome-molybdenum) and black-oxide finish, and using standard Cr-V hand sockets on an impact driver risks shattering. Cr-V steel is fully recyclable as scrap metal; the plastic clamshell case is not routinely recovered through curbside programs.
