Key Takeaways

  • Use a bow square to find the “zero” point.
  • Mark the string.
  • Wrap serving thread around the mark.
  • Tie and/or glue the nocking point(s).

Consistency is the key to mastering archery. That simple truth doesn’t only apply to how you shoot; you need to be able to depend on your gear to function the same way with every shot. After all, even the most skilled archers are only as good as their gear allows. Eliminating variables allows you to approach your target with pure confidence. 

What is a nocking point?

A nocking point is a visual indicator that shows you exactly where to position your arrow when setting up for a shot. Establishing and marking a nocking point prevents unintentional angled shots, which improves your shot-to-shot consistency and precision.

Here’s how to set a nocking point with a bow square and how to tie a nocking point with serving thread.

1. Find the “Zero” Point

A bow square, also known as a T-square, is a useful archery tool that can be used to measure your bow so you can fine-tune your setup based on solid data instead of rough estimates.

Attach the long section of the bow square to the bow string. Slide the bow square until its horizontal arm extends at a 90-degree angle and aligns perpendicularly with the arrow rest. The horizontal arm signifies where on the string the arrow will sit. This is the “zero” or “level” point.

2. Adjust the Angle

As you learn how to set a nocking point with a bow square, you’ll eventually find a nock height that fits your shooting style and skill level. Most archers set their arrows “nock high,” which means that the arrow’s nock sits slightly higher than its tip.

In other words, your nocking point should be positioned slightly above where the bow square’s horizontal arm sits flush at a 90-degree angle. Most archers position the nocking point within a range of 1/8" to 3/16" above the “zero” point. 1/8" is a good starting point. You can always adjust it up or down later.

3. Mark the String

That’s the basics of how to set a nocking point with a bow square! Now, you just need to mark the string before you move to the next step: learning how to tie a nocking point with serving thread.

Now, use a pencil, pen, or marker to mark where the serving thread will be tied to make the nocking point. Some archers use one nocking point and nock the arrow below it; others make two nocking points and nock the arrow between them. Mark the string accordingly.

4. Tie the Nocking Point

Tying the nocking point is another step that comes down to personal preference. You may prefer a bigger or smaller nocking point or a different knot style. Fortunately, you know how to set a nocking point with a bow square, so you can always untie and retry if necessary. Here’s a basic wrap-and-tie method to get you started.

  • Place the serving material against the bow string where you will tie the nocking point, leaving extra material hanging on both sides.
  • Tightly wrap the serving thread around the bow string until it’s the desired size and thickness.
  • Tie a few double-overhand knots to secure the wraps in place.
  • Cut the loose ends of the thread, or use a lighter to burn them away.
  • Optional: Lightly coat the nocking point(s) with string glue, super glue, or hot glue. Skip this step if you’re not 100% sure that your nocking point is positioned optimally.
