1/4" Drive Deep Metric Socket Set
The STEELMAN 78521 set contains nine chrome-vanadium steel sockets ranging from 6mm to 14mm. Heat-treated satin finishes give a non-slip grip when hands are greasy. Laser-etched size markings allow quick identification in low light. The clip-on storage rail keeps the sockets organised on a bench or in a drawer.
Check drive size and fastener range
Verify that your ratchet or breaker bar uses a 1/4-inch square drive before ordering. Confirm the fasteners you service fall within the 6mm to 14mm metric range supplied. The thin-walled profile suits confined spaces but cannot replace deep sockets for longer studs. California Proposition 65 warnings apply to chemicals in the product.
Clip-on rail and laser etching
The included storage rail snaps each socket into place, reducing time spent searching for the right size. Laser-etched markings resist wear better than stamped numbers, so sizing stays legible after heavy use. Satin finish resists corrosion without adding bulk that could limit access in tight areas. No additional software or accessories are bundled.

Questions about this item
Does the 78521 set include the clip-on storage rail shown in the photos, or must I buy a rail separately?
The nine deep sockets ship on a clip-on storage rail that is included in the box, so no separate rail purchase is needed.
Should I choose the 78521 nine-piece metric set or look for a larger SAE version for the same drive size?
The 78521 covers 6 through 14 mm in 1 mm steps; if your fasteners are metric this set matches them directly, while an SAE version would cover inch sizes instead.
Will the thin-walled 14 mm socket from the 78521 fit onto a 14 mm bolt head recessed inside a caliper bracket on my car?
Yes, the thin-walled design on every socket in the 78521 set is made to reach fasteners in confined spaces such as caliper brackets.
