Our take on the SQUIRE Stronghold Stainless Steel Padlock SQ-ST50S

The Squire Stronghold ST50S is a 50mm solid stainless steel padlock built for marine and outdoor use. It carries a CEN 3 security rating, a 6-pin anti-drill cylinder with 260,000 key differs, and a body Squire says survived 480 hours of salt spray testing. That puts it well above general-purpose brass or laminated padlocks for coastal, gate and shed duty, though it is heavier and pricier than a basic weatherproof padlock. It suits boat owners, dock and yard security, and anyone locking up in wet or salty air.

Questions and answers

Is the ST50S suitable for saltwater and coastal use?
Yes. The body is solid stainless steel and Squire rates it for 480 hours of salt spray, so it is built for marine and coastal conditions. Rinse it occasionally and keep the keyway clean to get the most from it.
What does CEN 3 mean?
CEN grades padlocks from 1 to 6 on resistance to attack. CEN 3 is a mid-to-high grade, well above basic household padlocks, and is often the level insurers ask for on outbuildings.
How does it compare with a brass weatherproof padlock?
Stainless steel resists salt and rust better than brass, and the CEN 3 rating and anti-drill cylinder are stronger than most brass padlocks offer. The trade-off is more weight and a higher outlay.
Can I get several locks keyed alike?
Squire offers keyed-alike options on the Stronghold range, but availability depends on the seller. Check the listing or ask the store before ordering if you need matching keys.
What size shackle does the 50mm body take?
The 50mm body uses a shackle sized for standard hasps and lockers. Measure your hasp opening before buying, since a 50mm body is chunkier than a 40mm padlock.
Is it too heavy for everyday carrying?
It is noticeably heavier than a small brass padlock, so it suits fixed applications like gates, sheds and boat lockers rather than pocket carry.
Where is the SQUIRE Stronghold Stainless Steel Padlock SQ-ST50S cheapest?
At Smallwood Lock & Supply, for $99.45, 35% under what the other stores charge, as of our latest check.
