Spoke Wrench Heads

The perfect pairing for the Spoke Torque Wrenches

Precision machined and built to last.

Fasst Company’s Spoke Torque Wrench Heads are machined to precisely fit your bike’s nipple size. Our precise head tolerances minimize the opportunity to damage your nipples when maintaining your wheel. We do not produce our Heads to fit multiple nipples like other brands. Short cutting the Head applications, making a Head to fit multiple size nipples leads to rounded off and damaged nipples, which is not acceptable to us. In fact other companies that offer spoke torque wrenches design them to fit Fasst Company’s Heads as they know theirs will fail or they do not offer the actual size of Head for your nipple.


    1. Absolute precision

      Precise fit to your bike’s nipple.

    1. Vast applications

      12 Head Sizes available

  1. Lifetime warranty

    Lifetime warranty, if you break a Head, send it to us, we’ll replace it for free. Rider is responsible for all shipping costs. This excludes Spline Drive Heads as they can wear out over time.


Lifetime Warranty on materials and craftsmanship. If you break a Head, send it to us, we’ll replace it for free. (Rider is responsible for all shipping costs. This excludes Spline Drive Heads as they can wear out over time).

Frequently Asked Questions

Do your wrench heads break?

No, since 1999 we can count the number of heads that broke on one hand. The few that did were used all day, every day, by a wheel manufacture using our Spoke Torque Wrench to build spoked car wheels that required a very high torque.
