American LockA5200D 1-3/4" Solid Body Steel Padlock

TL;DR: Solid padlock with advanced security features, surpasses average locks, great value, but there are higher-end options.Welcome to the clandestine world of padlock hierarchy, where not all locks are created equal. When I got my hands on this American Lock, I knew I was dealing with a heavy hitter in the lock league. Yes, American Lock joined forces with Master Lock, and some say it's like mixing champagne with soda, but I struck gold – mine was a genuine American Lock.This padlock isn't just a piece of metal; it's a fortress. With ball bearing locking lugs that laugh in the face of shimming attempts, an anti-bypass wafer that says "nice try" to intruders, and a core filled with serrated and spool pins – it's like the lock version of a high-security bank vault. It's a step above those run-of-the-mill locks you'd find at Home Depot, yet it doesn’t burn a hole in your wallet.While this lock is a bruiser in its own right, it's important to remember it's not the heavyweight champion of the lock world. If you're guarding Fort Knox, you might want to scout around for something even more formidable. But for the average Joe looking to keep their garden shed or gym locker safe, this lock is a solid, trusty choice.

Many people don’t recognize that there are various levels of padlock security. I know American Lock was purchased by Master Lock and the quality is declining, but the Lock I received was a genuine American Lock. This Lock has ball bearing locking lugs (prevent shimming), anti-bypass wafer, and serrated and spool pins in the core. The level of pick protection is superior to your typical Home Depot padlock without getting crazy expensive. This is a solid lock, but there are certainly better ones out there if you need to level security.

To start, I'm no locksmith expert. I've been lock picking for about a year.This is the greatest lock I have ever come across. All steel lock except the pin assembly is brass. Tough and hefty. I bought this lock for lock picking. I haven't been able to pick it and am not ashamed at all to admit it. I have taken apart the pin assembly and both sets of pins are serrated and spool. Every pin in this lock is a security pin. And to make it even tougher, you need to put a lot of torque on the key when you open it. So what does that mean? If you're trying to pick it, you can't tell if you're putting enough tension on the wrench or not. The springs are incredibly strong. This is one tough lock. I recommend it for security. By all means try and pick it, but I have yet to get it.

Used these same padlocks 30 years ago in construction. Heavy duty, work smoothly for years

This lock works as advertised, I just wanted to add a picture for anyone considering buying one to use on a moving truck. I used mine while renting a 10 foot U-Haul moving truck; I believe Penske trucks have similar latch dimensions. The American Lock A701D also fits on the latch and is an upgrade option.Both American Lock models get good reviews on lockpicking/security forums - they are likely to deter most low=level thieves. If you're smart about parking your truck you'll probably only be at risk for people carrying heavy hydraulic cutters or angle grinders. I parked in a fairly well-lit lock near a bustling hotel and had no problems.

This lock was used to protect my tool room at the rear of my house.I am not a technical expert but the lock looks strong and makes me feel more protected.

Built to survive a nuclear blast.

Wow, I was highly impressed when I received this lock. Very sturdy, thick, and you'd expect to pay more for this well made lock. Consider this, when I write reviews, I have had experience(s) with these products and I am a bit conservative on my reviews. In other words, I will not and do not overdo my reviews. I give it straight so the public is well informed so the public can make a well informed decision.
