Padlocks: FAQ

How do I ensure the shackle fits my gate or locker?

Always check the shackle diameter in millimeters (mm) listed in the technical specifications. Compare this measurement to the hole size of your latch to ensure the lock fits securely without being too thick to insert.

How can I tell if a padlock is truly rust-proof for outdoor use?

Look for '304 Stainless Steel' or 'Hardened Brass' in the material specs. Sellers that provide salt-spray test results in their product images are the most reliable choices for high-humidity or coastal environments.

What specs indicate a lock is resistant to bolt cutters?

Prioritize shackles labeled as 'Hardened Steel' or 'Boron Alloy.' Additionally, choosing a 'Shrouded Shackle' design makes it physically difficult for bolt cutters to grip the metal, significantly increasing security.

What should I look for in a smart biometric padlock?

Check the IP rating (IP65 or higher) for water resistance and ensure it has an emergency USB charging port. Always verify if the lock includes a physical backup key in case the battery fails or the sensor malfunctions.

Recommendations for buyers

✓
Material Composition
Select hardened steel for maximum theft prevention or solid brass and stainless steel for superior corrosion resistance in outdoor settings.
✓
Locking Mechanism Type
Disc-detainer and high-pin count cylinders are much harder to pick than standard wafer or low-pin locks. Check the 'cylinder' specs for these terms.
✓
Shackle Clearance
Ensure the vertical and horizontal clearance of the shackle provides enough room for your specific application, such as thick chain links or double-door handles.
✓
Security Rating Certifications
Look for mentions of international standards like CEN or ASTM ratings in the description to verify the manufacturer's durability claims.
