Kreg Pocket-Hole Jig Spacers widen hole spacing on the 320. Learn what they do, how thickness affects setup, and whether you need them for your project.
Quick answer
Kreg Pocket-Hole Jig Spacers let you increase the distance between pocket holes on a Kreg Pocket-Hole Jig 320. You need them when your project calls for wider hole spacing than the jig provides out of the box, such as when joining wider boards or matching an existing hole pattern.
Why hole spacing matters more than material thickness
Pocket-hole spacing is about distributing clamping pressure and screw placement across a joint, not about the thickness of the material itself. Thicker material usually requires a longer screw and a different drill-guide setting, but it does not automatically require spacers. Spacers change the distance between holes along the length of the jig, which helps when you want more screws across a wide glue-up or when you are trying to align new holes with an existing pattern.
When spacers are not the right fix
If your pocket holes are too close to the edge or the screw is breaking out, the problem is usually drill-guide height, screw length, or clamp placement, not hole spacing. Spacers will not correct those issues. Also, the spacers are designed for the 320 jig; they are not a universal accessory for every Kreg jig model. Check your jig model before buying.
Common questions about Kreg pocket-hole jig spacers
- What do Kreg Pocket-Hole Jig Spacers actually do?
- They sit between the drill guides on the Kreg Pocket-Hole Jig 320 and increase the spacing between pocket holes. That gives you more options for screw placement when a project needs wider hole spacing than the jig provides by default.
- How does pocket-hole spacer thickness affect setup?
- The supplied catalog does not list a specific thickness for these spacers, so do not assume a measurement. What matters is the change in spacing they create, not a thickness number. If you need an exact spacing dimension, measure the spacer or test-fit before drilling. Test the spacing on scrap wood before committing to your project piece.
- Do I need pocket-hole spacers for thick material?
- Not automatically. Material thickness mainly affects screw length and drill-guide height, not hole spacing. Spacers are for changing the distance between holes, so use them when your project layout calls for wider spacing, not simply because the board is thick.
- Will these spacers fit my Kreg jig?
- They are designed for the Kreg Pocket-Hole Jig 320. They are not listed as compatible with other jig models, so check your jig model before ordering.
- How do I set up the spacers on the jig?
- Place the spacers between the drill guides as needed to increase spacing, then secure the guide according to your jig's normal setup. The exact steps depend on your jig, so follow the instructions that came with your 320.
