Hasps — Lockout Hasps & Hasp and Staple Hardware for Safety & Security

AIMS Industrial supplies hasps for lockout tagout (LOTO) safety programs and general security applications. Our range from Master Lock includes multi-lock aluminium lockout hasps, spark-proof aluminium hasps, hinge hasp and staple sets, snap-on LOTO hasps with tag holders, and wrought steel hasp and staple hardware — providing compliant group isolation points and secure physical access control for industrial and trade applications.

Hasp Types & Lockout Applications

• 6-Lock Aluminium Lockout Hasps: Master Lock spark-proof aluminium lockout hasps accommodate up to 6 padlocks simultaneously (25mm jaw diameter) — allowing multiple workers to apply personal locks to a single isolation point in group LOTO procedures without releasing the energy source until the last lock is removed.
• 2-Lock Lockout Hasp & Padlock Kits: Master Lock 2-lock hasp and padlock combination kits provide a complete, ready-to-use LOTO starter solution — including aluminium hasp and compatible safety padlock for single-worker isolation of electrical panels, valves, and pneumatic systems.
• Snap-On Lockout Hasps: Master Lock red aluminium snap-on lockout hasps with integral tag holders combine padlock isolation with visual identification tags in a single unit — simplifying LOTO documentation and improving compliance visibility during group isolation events.
• Hinge Hasp & Staple (Security): Master Lock hinge hasp and staple sets in steel provide conventional swinging hasp hardware for sheds, toolboxes, cabinets, and gate frames — compatible with standard padlock shackle sizes for basic access security.
• Wrought Steel Hasp & Staple: Master Lock hard wrought steel body hasp and staple sets provide heavy-duty mechanical security for gates, workshop doors, and storage containers — forged steel construction resists pry and impact attacks compared to pressed steel alternatives.

Hasp Selection & LOTO Program Integration

• Multi-Lock Capacity: Select hasp jaw capacity to accommodate your maximum expected group isolation size — 6-lock hasps from Master Lock cover most industrial group LOTO procedures; complex isolation points with larger teams may require multiple hasps and a secondary group isolation device.
• Spark-Proof Material: Aluminium lockout hasps are spark-proof and non-conductive — the required choice near flammable gases, vapours, or explosive atmospheres where steel-on-steel sparking could cause ignition. Never substitute steel hasps in Ex-rated areas.
• LOTO Procedure Compliance: Australian LOTO programs operating under AS 4024.1602 require individual worker isolation with personal padlocks — multi-lock hasps are the correct hardware for multi-worker group isolation, not master-key padlock schemes.
• Hasp Size & Shackle Compatibility: Verify hasp jaw (staple) diameter matches your padlock shackle diameter before purchase — Master Lock 25mm jaw hasps are compatible with standard 6mm and 7mm shackle safety padlocks. Mismatched sizes prevent proper padlock seating and reduce LOTO security.

People Also Ask — Hasps

Q: How many padlocks can a lockout hasp take?

Master Lock 6-lock aluminium lockout hasps accommodate up to 6 padlocks simultaneously (25mm jaw diameter), letting multiple workers apply personal locks to a single isolation point during group LOTO procedures — the energy source isn't released until the last lock is removed. Isolation points needing more than 6 workers may require multiple hasps plus a secondary group isolation device.

Q: Why are lockout hasps made from aluminium rather than steel?

Aluminium lockout hasps are spark-proof and non-conductive, which makes them the required choice near flammable gases, vapours, or explosive atmospheres where steel-on-steel sparking could cause ignition. Steel hasps should never be substituted in Ex-rated areas.

Q: Can I use a standard hinge hasp and staple for LOTO isolation instead of a lockout hasp?

No — a hinge hasp and staple is conventional swinging security hardware in steel, used on sheds, toolboxes, cabinets, and gate frames, not designed for energy isolation. A lockout hasp (aluminium, multi-lock) is purpose-built for LOTO, letting several workers each apply a personal padlock to one isolation point.

Q: What size padlock shackle fits a standard lockout hasp?

Check that the hasp jaw (staple) diameter matches your padlock shackle diameter before purchase — Master Lock 25mm jaw hasps suit standard 6mm and 7mm shackle safety padlocks. A mismatched size prevents the padlock from seating properly and reduces LOTO security.

Q: Does a multi-lock hasp replace individual worker padlocks in a LOTO program?

No — Australian LOTO programs under AS 4024.1602 require each worker to isolate with their own personal padlock. A multi-lock hasp is the correct hardware to let multiple personal padlocks secure one isolation point together; it isn't a substitute for individual locks via a shared master-key scheme.

Q: What's a snap-on lockout hasp used for?

Master Lock's red aluminium snap-on lockout hasps combine padlock isolation with an integral tag holder in one unit, so a lockout tag can be attached at the same point the padlock is applied — simplifying LOTO documentation and improving visibility during group isolation events.
