Introduction: Why Stainless Steel Padlocks Are Essential
Whether you’re securing a locker, a toolbox, or outdoor equipment, a stainless steel padlock provides the right mix of durability, corrosion resistance, and compact design. Our padlocks come in three sizes—21mm, 25mm, and 32mm—offering flexible options to suit different needs.

Key Features of Stainless Steel Padlocks
Durable 304 Stainless Steel
All three padlocks use 304 stainless steel for the body and shackle, ensuring excellent resistance to rust and weather conditions.
Brass Cylinder Core
Each padlock is equipped with a brass lock core for smooth operation and long-lasting reliability.
Unique Keys for Every Lock
Every lock comes with two brass-plated keys, and all locks are non-keyed alike, meaning no two locks can be opened with the same key.
