Product Information

Full details

The Master Lock 160mm Wrought Steel Single Hinged Hasp is designed for homeowners and professionals seeking a flexible security solution for sheds, storage containers, and cellars. Its standout benefit is the hinged design that allows for installation on angled surfaces where traditional rigid hasps fail. While it provides robust protection against cutting and prying thanks to its hardened boron steel construction, users should note that the unit requires a padlock with a shackle diameter suited for its 11mm bore, which must be purchased separately.

FAQs

Does this hasp come with a padlock?

No, the hasp is sold as the locking mechanism only. You will need to source a padlock separately.

Can this be used on a metal storage container?

Yes, provided you use the appropriate hardware for metal surfaces, such as bolts and nuts, rather than standard wood screws.

Is this hasp weather-resistant?

It is made of durable wrought steel, but like all steel hardware, we recommend regular maintenance and cleaning to prevent rust in exposed outdoor conditions.

What is the bore size?

The padlock eye has an 11mm bore diameter.

Why is the boron steel construction important?

Boron steel is a hardened alloy that is significantly more resistant to cutting and sawing than standard mild steel.

Troubleshooting

Hasp hinge feels stiff or tight

Apply a small amount of silicone-based lubricant or machine oil to the hinge pin to restore smooth motion.

Padlock shackle does not fit easily

Ensure you are using a padlock with a shackle thickness of 11mm or less and that the hasp eye is not obstructed by debris.

Hasp looks misaligned after mounting

Check if the door has sagged or shifted. You may need to relocate one side of the hasp to ensure the two halves meet correctly.

Pros and Cons

Pros

  • Excellent flexibility for non-standard mounting angles
  • High-security hardened boron steel composition
  • Deterrent design includes concealed hardware
  • Wide compatibility with standard padlocks via 11mm bore

Cons

  • Padlock not included with purchase
  • Requires proper surface preparation for angled mounting
  • Maximum security relies on quality of mounting surface

Setup, Compatibility & Care

To install, ensure the hasp is mounted onto a solid base material—preferably treated timber or metal. Use high-quality, corrosion-resistant screws that penetrate deep into the door frame for maximum "rip-out" resistance. For angled applications, test the swing of the hinge before marking your pilot holes to ensure the padlock eye aligns perfectly when the door is in the closed position.

Maintain the hardware by applying a light machine oil to the hinge pin once a year to prevent seizing, especially in coastal or high-humidity climates. Regularly check that the mounting screws remain tight, as vibration from frequent door use can loosen them over time.
