The ZT Outsert™ increases the strength and durability of the Evolusion Arrows® Tomahawk shaft. 

The ZT Outsert™ has component tolerances that are superior to outserts that use a simple slide-over sleeve, or a basic screw-fit post.

The unique design of the insert and collar ensures complete concentricity between the two components AND also between the assembled ZT Outsert™ and the Tomahawk shaft. 

Sold in a 12-pack.

The ZT (zero tolerance) Outsert system is an optional component. This component is NOT included with the Tomahawk shaft. The 55 grain S/S Half-Out is the included component supplied with the Tomahawk shaft.

SPECIFICATIONS

  • Precision CNC milled 7075-T6 aluminium insert - 30 grains (31.5 mm post length).
  • Stainless steel sleeve - 55 grains (16.5 to 17 mm shaft overlap).
  • 5/16" diameter face for maximum contact with any broadhead seat.
  • Use with any 5/16" diameter field points.
  • Adds 14 mm or 9/16" to the finished length of the shaft.

  • Three sizes are offered to fit the following spines perfectly:

    Size 1 (1 groove) - 250 spine.
    Size 2 (2 groove) - 275 spine.
    Size 3 (3 groove) - 300 spine.

    There is no ZT Outsert offered for the 350 and 400 spine Tomahawk shafts.

    The ZT Outsert is designed primarily for use with the Tomahawk shaft.
    We cannot recommend other brands of shaft that will be compatible.

    ZT Outsert INSTALLATION

    TIP! Before you start, pre-cut some small pieces of clean cotton rag. You will need these to clean arrows and components and remove excess adhesive. You can't have too many!

    1/ Square the end of the arrow shaft.

    2/ GENTLY try to dry-fit the sleeve to the shaft. The stainless steel sleeve of the ZT Outsert has been designed so there is no free-play on the carbon shaft.
    If it won't slide on easily, don't try to force it on. Due to slight variations in the outer diameter of carbon shafts between batches, the shafts may need to be lightly sanded to a distance of 17 mm along from the saw cut. This is normal procedure and is easy to do.

    Using 240 grit sandpaper, hold the abrasive between your thumb and finger while rotating the shaft. After 8 to 10 rotations, clean the carbon surface and gently test-fit the sleeve.
    Continue this process until just enough carbon is removed, and the sleeve slides smoothly onto the shaft. Remove all dust with isopropyl alcohol.
    Sanding will not damage the shaft - the sanding actually acts as a key for the adhesive.

    3/ Once the sleeve fit the shaft with a smooth sliding fit, clean the Outsert components AND the carbon shaft with isopropyl alcohol using a clean piece of cotton rag. Let the alcohol evaporate fully before starting the gluing process.

    4/ Both components should be glued to the shaft - this will increase the strength of the Outsert system.
    The use of a slow-set two-part epoxy is highly recommended for all insert and outsert installation. Slow-set epoxy (like AAE Epoxy) allows plenty of time to get the installation right and has good impact resistance once fully cured.

    Beware! Cyanoacrylate adhesives like Loctite, bond components very fast. There is little time to move the outsert components into place. If you get it wrong with this type of adhesive, the arrow may be rendered un-usable.
    Slow-set epoxy adhesive is the best choice, especially if your arrow-building experience is limited.

    • Mix the epoxy adhesive according to the instructions.
    • Apply a small amount of adhesive to the inside of the shaft using a toothpick or similar tool.
    • Apply the adhesive sparingly to the outside of the shaft and to the inside of the stainless steel sleeve (the smooth end, not the threaded).
    • Push the sleeve onto the shaft, rotating it to ensure even adhesive coverage.
      Remove the excess glue.

    • Screw a field point into the aluminium insert to allow a firm grip on the component.
      While holding the field point, sparingly apply adhesive to the insert post - just enough to lightly coat it.
      Also put a small dob of adhesive on the outer insert thread - adhesive in the thread increases the strength of the outsert.
      Hold both components and push (and rotate) the insert into the shaft, and screw the insert tight into the stainless-steel sleeve.
      If there is too much glue on the thread, the insert may not seat fully. Don't worry - unscrew the insert, wipe a little glue off the thread and screw it in again. Screw back and forward until the two components seat fully.

    5/ Once glued stand the arrow shafts vertically, outsert down, to ensure epoxy doesn't creep along the inside of the shaft. Wait 20 to 24 hrs before shooting the arrow.

    Truly excellent

    Tomahawk shafts are the best Arrows I’ve shot I’ve used all the major big brands and are they shoot the most true and accurate. Evolusion Arrows are my absolute go to, for hunting, target and 3D
