Padlock Selection — Quick Reference
Padlock selection turns on application (security vs LOTO safety), body material (brass/thermoplastic/hardened steel), shackle hardness, and keying. LOTO + security are different jobs requiring different padlock specifications.
| Padlock Type | Application | Compliance |
|---|---|---|
| Master Lock Thermoplastic LOTO (Safety) | Equipment isolation — colour-coded by trade/shift | AS/NZS 4836 + AS 4024 isolation |
| Master Lock Aluminium LOTO | Heavy-duty isolation, mining + petrochemical | AS/NZS 4836 |
| Brass Body Padlock | General security — sheds, gates, equipment cabinets | Per Master Lock series rating |
| Hardened Shackle Padlock (Shrouded) | Bolt-cutter resistant — yards, containers | Hi-security boron-alloy shackle |
| Hidden Shackle Padlock | Container, gate, trailer security — anti-cut design | Hi-security tamper-resistant |
| Adjustable Shackle | Multi-purpose — different hasps + applications | Per series |
| Brady LOTO Padlock | LOTO programs with Brady station integration | AS/NZS 4836 |
| Keyed Alike (KA) | Master-keyed systems — one key opens many locks | Site-procedure dependent |
| Keyed Different (KD) | Personal isolation only worker can remove | One-person-one-lock LOTO principle |
Critical LOTO rule: One person, one lock, one key. NEVER share LOTO padlock keys. Personal lock can only be removed by the person who applied it (or formal authority-removal procedure for absent worker). Brands: Master Lock, Brady. Companion: lockout/tagout, safety equipment, LOTO guide.
Padlocks — Safety, Brass & High-Security Padlocks for Industrial & Trade Use
AIMS Industrial stocks a comprehensive range of padlocks for workplace security, lockout tagout (LOTO) safety programs, and general access control. Our range from Master Lock and Brady covers thermoplastic safety padlocks, brass body padlocks, shrouded hardened shackle padlocks, hidden shackle padlocks, and adjustable shackle models — meeting the security and safety requirements of industrial facilities, warehouses, and critical infrastructure sites across Australia.
Padlock Types & Applications
- Safety Lockout Padlocks: Master Lock 410 Series thermoplastic safety padlocks are the industry standard for LOTO programs — available in multiple body colours for energy source identification, with non-conductive bodies and corrosion-resistant shackles for electrical, chemical, and outdoor applications.
- Brass Padlocks: Master Lock Fortress brass body padlocks and 40mm brass padlocks provide weather-resistant general security for gates, sheds, storage lockers, and light industrial access control — traditional brass construction resists corrosion in outdoor and humid environments.
- Shrouded Shackle Padlocks: Master Lock 40mm brass padlocks with hardened steel shrouded shackles protect the shackle from bolt-cutter attack — the recessed shroud limits cutting tool access for higher-security applications on toolboxes, trailers, and site equipment.
- Hidden Shackle Padlocks: Master Lock 73mm solid steel flat back padlocks with hidden shackle design provide maximum cut, saw, and pry resistance — engineered for high-security applications where visible shackle attacks are a specific threat.
- Adjustable Shackle Padlocks: Master Lock 1950DAU 50mm diamond brass padlocks with adjustable shackle accommodate a range of hasp, chain, and bar configurations without requiring multiple padlock sizes — versatile for varied site and access point applications.
- Brady Keyed-Alike Safety Padlocks: Brady brass safety padlocks in keyed-alike (KA) configurations allow multiple padlocks to be operated by a single key — simplifying key management for supervisors and safety officers in large LOTO programs.
Padlock Selection & LOTO Compliance
- Safety Padlock Colour Coding: Australian LOTO procedures typically assign individual padlock colours by trade or energy type — Master Lock 410 Series is available in red, blue, yellow, orange, green, and purple to support multi-trade and multi-energy isolation programs.
- Shackle Length & Clearance: Match shackle length to the hasp or chain aperture — short shackle for hasp locks; long shackle for chain, gate bar, and cable applications. Master Lock adjustable shackle models cover both short and long shackle requirements in a single product.
- Keyed-Different vs. Keyed-Alike: Keyed-different padlocks are standard for individual LOTO where each worker controls only their own isolation; keyed-alike sets are used in supervisor override and masterkey systems — select appropriate keying based on your site LOTO procedure.
- Corrosion Resistance: For outdoor, marine, or chemical environments, specify Master Lock padlocks with brass or stainless bodies and boron-hardened shackles — standard carbon steel shackles corrode rapidly in wet and chemically aggressive environments, jamming locking mechanisms over time.

People Also Ask — Padlocks and Industrial Locking
Q: What padlocks does AIMS stock?
Security padlocks (brass, laminated steel, hardened steel — for storage, gates, equipment security), Lockout/Tagout padlocks (compliant with AS/NZS 4836 for isolation procedures — colour-coded, key-retaining design), combination padlocks (no keys to lose), weatherproof padlocks (outdoor exposure), and specialty industrial padlocks. Brand mix includes Master Lock, ABUS, BramleyLock, and specialty industrial lock brands. Match lock to application — security padlock for theft prevention vs LOTO padlock for personnel isolation.
Q: Brass or laminated steel padlock body?
Brass body: corrosion-resistant, naturally weather-resistant, suits outdoor and marine exposure. Lower attack resistance than steel. Laminated steel: stronger against cutting and prying attacks, hardened layered construction. Less corrosion-resistant — better for indoor use. Premium boron-alloy shackle padlocks combine both: brass or coated steel body + boron-alloy shackle. For outdoor gates and storage: brass. For high-security indoor: laminated steel. Match material to environment and threat level.
Q: What shackle diameter for which application?
4-6mm shackle: light security (tool boxes, lockers). 8-10mm: workshop and trade security (gates, sheds, containers). 12-14mm: heavy-duty industrial security (mining sites, transport, high-value equipment). Larger shackles harder to cut but limit fitting in hasps. Match shackle to the hasp + chain + the threat level. Specialty padlocks: shrouded shackle (covered for cut resistance), straight shackle for chain locks.
Q: Personal LOTO padlock vs security padlock?
Security padlock: keyed for multiple-user access if needed (multiple keys distributed), normal padlock design. Used to secure equipment against theft. LOTO padlock: key-retaining design (key can only be removed when lock is open — prevents accidental locking), one key per worker, colour-coded for personnel identification. AS/NZS 4836 LOTO procedures REQUIRE personal LOTO padlocks for personnel isolation. Don't substitute security padlocks — the design difference matters for safety compliance.
Q: Can I get padlocks keyed alike?
Yes — most quality padlock brands support keyed-alike sets (one key opens multiple locks) — useful for fleet, gate, or facility applications where one person needs access to many locks. Brand-specific: Master Lock, ABUS, and BramleyLock all offer keyed-alike service. Specify when ordering — minimum quantities apply for custom keying. Custom master-key systems (multiple users with different access levels) available for larger facilities through Master Lock's commercial program.
