How to Install a Hasp and Staple Lock

Are you keen to learn how to install a hasp and staple lock yourself? Well, you’re in luck as we have put together a handy guide on how to install a hasp and staple!

If you are looking to secure a toolbox, gate or power box on your house, or perhaps you might be looking to add a WAS (Western Australian Services Lock) lock to your meter box – then this guide is for you.

A hasp and staple (also commonly referred to as a ‘hasp lock’) are simple and easy to install, plus they are a low-cost solution.

Below we have written down a few steps plus the tools you may need to install a hasp and staple DIY.

Firstly, what is a hasp and staple or hasp lock?

A hasp is a hinged metallic strap/band that fits over a metallic loop (staple). It is mostly secured by a padlock.

A hasp lock is the same but instead of having a loop (staple) it has a locking mechanism with a key, so you won’t need a padlock.

Tools required to install a hasp and staple:

  • Pencil or pen 
  • Battery drill/driver or corded drill
  • Drill bits (depending on the screws used)
  • Screwdriver (Phillips or flat) or driver attachment for your battery drill/driver
  • Appropriate screws (depending on what you are attaching your hasp lock to – for example metal screws are required if you are fitting the hasp onto a tin or steel box or cabinet.)

Pro tip: By using countersunk machine screws with a nut and washer on the under or inside of the installation will amp up the level of security.

Step 1

Buy the right-sized hasp and staple/hasp lock for your application.

Step 2

Place the hasp in the desired position/height on the door/box. Hold the plate in position with one hand and swivel the arm out to show the holes for screws in the plate. Mark the locations of each hole with a pencil/pen.

Pro tip: If you place masking tape in the desired area before taking any steps you can minimise any damage done to paint.

Step 3 (If you don’t want to drill holes you can skip to Step 4)

Drill the holes as marked in the previous step. Make sure to use a smaller diameter drill than the width of your screw, this will prevent any cracking or splitting of wood frames.

If you are following our Pro Tip from the Tools Required section, please note the holes will need to be drilled the same size as the machine screws.

Pro tip: If you don’t want the drill to slip you can mark the holes by hitting a nail lightly into the marked spots first.

Step 4

Grab your battery driver or screwdriver, place the hasp over the holes drilled or marked.

Drive-in those screws until the hasp is secure against the door, door frame or lid wherever you have decided to place it.

Pro tip: Don’t drive the screws all the way in with your battery driver, leave them sticking out just a bit then complete the final tighten with your screwdriver. This will stop you from potentially stripping the heads.

Step 5

Attach the padlock loop or staple. Place the loop into the slot on the hasp, holding the two pieces together close the assembly so that the loop plate is against the surface. Holding the loop plate where it has landed, fold the hasp back out of the way. Your loop or staple is ready to be screwed on if you follow Steps 2,3,4 for marking drilling and driving the screws.

Pro tip: Read all the steps described above before you start anything, so you understand what to do and if you want to skip a few things like drilling.

And that’s it! You’ve installed your hasp and staple!

Now your hasp and staple are ready to put your padlock through to secure your door. If any of the above seems too complicated or if you need it done right now, please give the awesome team at Lock, Stock and Farrell a call or contact us online.
