Bohning's Signature Nock fits Standard Diameter shafts with an ID of .246” (commonly known as S-Nock or 6.5mm shafts). Signature Nocks feature a smooth throat of .109 (2.77mm) and a raised index. The Bohning Signature Nock fits all standard Carbon arrows. Each Signature Nock weighs an average of 12.0 grains (778mg).

Tech tip: for easier insertion and indexing, apply a small amount of Bohning's Tex-Tite or Seal-Tite Wax to the nock shank.

NOT ALL BRANDS OF NOCKS ARE CREATED EQUAL
At Bohning, every nock style must pass the following steps before introduction to the market:

1. Computer simulations identify potential weak points.
2. Destructive testing methods expose possible design flaws or material defects.
3. Accelerated life cycle testing using a custom-built bow is performed at kinetic energy levels exceeding 110 ft-lbs (nearly twice that of most hunting bows). A single nock must withstand over 1000 shots or it goes back to step 1.
Proudly manufactured at the Bohning Factory in Lake City, Michigan, United States.
