Master Lock Fortress 30mm Brass Padlock (FM1830DAU) – Keyed Padlock

Instantly establish highly reliable, rust-proof security across your facility and perfectly safeguard your personal belongings with the highly durable Master Lock Fortress 30mm Brass Padlock (FM1830DAU). In high-turnover environments like school locker rooms, shared staff cabinets, and outdoor residential sheds, utilizing cheap, poorly constructed locks leads to devastating rust, jammed mechanisms, and highly vulnerable security. This elite, compact keyed padlock acts as the ultimate daily security solution. Forged from an incredibly resilient, solid brass body, it completely repels moisture and harsh weather, guaranteeing flawless operation and total immunity against destructive worksite corrosion.

Engineered for unwavering commercial durability and absolute convenience, the FM1830DAU features a highly cut-resistant 5mm hardened steel shackle, aggressively deterring opportunistic theft and defeating standard cutting tools. The precision-engineered dual locking levers internally secure both sides of the shackle, providing robust resistance against violent prying and brute-force hammer strikes. Perfect for outfitting multiple gym lockers, toolboxes, or electrical meter boxes, this highly versatile brass padlock is the definitive, hassle-free security upgrade for residential property owners and facility managers demanding trusted, long-lasting performance.

Who Is The Master Lock 30mm Fortress Padlock Ideal For?

The FM1830DAU delivers a rust-proof solid brass body, hardened steel shackle, and compact 30mm design. It is highly recommended for:

  • Gymnasiums & Schools: Utilizing a highly reliable, compact keyed padlock to perfectly secure personal student and staff lockers without the lock jamming from indoor humidity.
  • Residential Homeowners: Providing a secure, rust-proof entry point for side gates, electrical meter boxes, and outdoor garden sheds that are constantly exposed to driving rain.
  • Construction & Tradespeople: Deploying the highly durable, solid metal brass padlock to protect small, expensive hand tools inside a worksite toolbox from opportunistic theft.
  • Facility Managers: Taking absolute advantage of the Keyed Alike availability to secure multiple low-risk utility cabinets across a building without needing to carry a massive, heavy ring of keys.

Key Features and Performance Benefits:

  • Solid Brass 30mm Body: Forged for extreme survival. The heavy-duty 30mm body is cast from solid brass. This provides massive physical strength to survive drops and hammer strikes, while being completely and totally immune to rust and weather corrosion.
  • 5mm Hardened Steel Shackle: The absolute deterrent against cutting tools. The 5mm thick shackle is forged from heavy hardened steel, making it incredibly difficult for opportunistic thieves to cut with standard hand saws or small snips.
  • Dual Locking Levers: Absolute brute-force resistance. This advanced internal mechanism physically locks BOTH sides of the steel shackle tightly, violently resisting aggressive prying and extreme pulling force.
  • Compact & Lightweight Design: The perfect everyday security footprint. It provides serious, reliable protection without adding massive, clunky weight to a gym bag, delicate cabinet hinge, or toolbox latch.
  • Keyed Alike Capability: Engineered for massive commercial convenience. This specific model is configured to be 'Keyed Alike', allowing facility managers to purchase multiple locks that can all be opened using the exact same key.

What does 'Keyed Alike' (KA) mean for this padlock?

Keyed Alike means that all the locks within this specific Master Lock 'KA' batch are manufactured using the exact same internal cylinder. This allows you to buy 5 or 10 of these padlocks and open every single one of them using just one key.

Is the Solid Brass body good for outdoor use?

Yes, absolutely. Solid brass is naturally 100% immune to rust and corrosion. Unlike cheap iron locks that seize up in the rain, this solid brass body will survive brutal outdoor weather, making it excellent for garden sheds and side gates.

Will the 5mm shackle fit my gym locker?

Yes! A 30mm body with a 5mm shackle is the absolute perfect size for personal security. It is thick enough to resist cutting, but thin enough to effortlessly slip through the metal latch of almost all standard school, gym, and staff lockers.

Can I use this lock to secure a commercial shipping container?

Absolutely NOT. A 30mm body with a 5mm shackle is designed for light-duty personal security (lockers, cabinets, toolboxes). It is not large enough or strong enough to secure massive commercial shipping containers. You need a heavy-duty 64mm lock for that.

How many keys are included with this single lock?

This single blister pack padlock is supplied factory-sealed from Master Lock with two (2) precision-cut keys.

What does 'Dual Locking Levers' mean?

Cheap padlocks use a single, spring-loaded latch to hold the shackle down. Dual locking levers physically lock into deep notches on BOTH sides of the steel shackle, making the lock highly immune to being violently pried or hammered open.

Is it difficult to pick the lock?

It is highly resistant to covert entry. The internal cylinder features a precision 4-pin tumbler design. This makes it incredibly difficult and highly time-consuming for thieves to 'pick' or 'bump' the lock open without the original key.

Can I get this same lock but 'Keyed Differently'?

Yes. Master Lock manufactures this exact 30mm Fortress Brass padlock in both 'Keyed Alike' (KA) and 'Keyed Differently' (KD) variations. If you do not want your staff having keys that open other locks, ensure you purchase the KD version.

Will the shackle rust?

The shackle is made of Hardened Steel, which provides massive cut resistance but can eventually show surface rust if left in driving rain constantly. The brass body, however, will never rust.

Can I use this for my travel luggage?

While the 5mm shackle will fit many large duffel bags, it is a keyed lock. For international air travel, especially to the USA, it is highly recommended to use a combination 'TSA Approved' lock to prevent customs from cutting the lock off.

How many padlocks are in this specific pack?

This specific SKU (FM1830DAU) is a '1 Pack'. It contains exactly ONE 30mm brass padlock and its corresponding keys.

Do you offer trade pricing for schools and gyms?

Yes, Freshway Supplies provides highly competitive volume pricing and trade accounts for educational institutions, commercial gymnasiums, and facility managers ordering bulk cartons of padlocks. Contact us to establish your account.
