michael.a Posted January 11, 2021 Report Share Posted January 11, 2021 Was doing some routine maintenance and decided to check the t-nuts to which the toe and heel blocks attach to. All 4 used to attach the heel block had hairline fractures. 3 1 1 Quote Link to comment Share on other sites More sharing options...
SunSurfer Posted January 11, 2021 Report Share Posted January 11, 2021 @Michael_AEvidence supporting my impression that riding puts far more strain on the rear of our bindings than the front. When the base plate of my rear Bomber TD3 binding failed from metal fatigue, it failed at the heel end. Really useful to know that we need to check, and where. @michael.a sorry linked the wrong Michael above. 1 Quote Link to comment Share on other sites More sharing options...
TimW Posted January 11, 2021 Report Share Posted January 11, 2021 (edited) For intec surely the heel takes most load as it takes all the side to side bending moment. The toe will only take vertical load. For bails it will be more evenly distributed. Cant & lift will put the bolts at an angle on F2s, which will unevenly load the t-nuts, so for sure check them if running lift/cant Pricy t-nut btw Edited January 11, 2021 by TimW Spelling 2 Quote Link to comment Share on other sites More sharing options...
michael.a Posted January 12, 2021 Author Report Share Posted January 12, 2021 Yea you can see the T nuts bent in the angle of the lifts! I didnt have time to hunt for T nuts so I bought some shorter ones from Mcmaster (90572A310) and placed them in toe blocks and used the toe blocks in the heels as they still look good.

lowrider Posted January 12, 2021 Report Share Posted January 12, 2021 Crack is binding fastener t-nut not boot heel . The crack is where the large diameter (wings )meet the small diameter. Quote Link to comment Share on other sites More sharing options...

This thread is about the tee nuts that mount the F2 heel and toe blocks to the bindings, but the tee nuts that hold the Intec heels on the boots can fail too. Moisture trapped in the boots helps promote the failure. Here are some failed tee nuts from boots: 1 Quote Link to comment Share on other sites More sharing options...

MNSurfer Posted January 14, 2021 Report Share Posted January 14, 2021 What are people getting for a lifespan, on the original T's? Of course it is all rider/mileage dependent, but just curious. Quote Link to comment Share on other sites More sharing options...
wulf Posted January 14, 2021 Report Share Posted January 14, 2021 (edited) Been replacing them just once in 10y. Only for safety reasons. Replaced them by stainless steel versions. I do ride around 10-15 days per season. F2 Race. NO intecs. SL-ish board sizes. EU Alps conditions - hardpack, mostly man-made snow everywhere. My impression is that Intecs place a HUGE amount of force on the t-nuts. Whereas the regular Race version flexes a tad more.

Of course it is all rider/mileage dependent, but just curious. These bindings were at least 10 years old and the toe/heel blocks were last inspected 5 years ago. Used about 10 days per season?

st_lupo Posted January 15, 2021 Report Share Posted January 15, 2021 I've had to replace two cracked t-nuts in my race-ti bindings (non-intec) over a span of 5 years, with 20 to 30 days of riding per season. I ordered replacements (original F2 parts) from yyzcanuck, definitely don't wanna go the ebay route for these parts. Maybe McMasters has something?

ktv Posted February 1, 2022 Report Share Posted February 1, 2022 I took my bindings off when packing to return home from Colorado on Sunday to find this on my rear foot heel bail. It seems to have suffered the same stress fracture but sheared off, and as I kept riding without knowing it, started pulling through. I had assembled my bindings the previous Saturday night, putting the rubber cover over the binding, and not noticing this. So it happened within the week of riding. I also ride standards, not Intecs. I guess I need to check all my bindings yearly now as well and start ordering replacement T-Nuts. Quote Link to comment Share on other sites More sharing options...
Chouinard Posted February 2, 2022 Report Share Posted February 2, 2022 I did and found this on my rear binding when I moved the front block forward on my F2 Intec Titanium. Quote Link to comment Share on other sites More sharing options...
