Telemark Binding Mounting: Screws vs Inserts for Strength

In this video I test the pullout strength of the two most common types of fasteners used to mount telemark bindings to skis. When people have issues with their bindings pulling out of their skis, inserts are often recommended as the be-all end-all for super strong mounts. I have always found this claim dubious. The higher thread count and greater circumference of the threaded inserts would suggest a higher total surface area than traditional binding screws. In practice the binding screws have much more thread depth, and resemble screws designed to be used in wood, which is what skis are primarily made of. This issue is compounded by the fact that inserts are much more difficult to install, making the mounts more likely to be compromised from the beginning. Using a torque wrench mounted to a hammer claw, I pull both types of fasters out of three different skis representing three different layups (metal laminate, wood/fiberglass, and paulownia/carbon). The results may surprise you. DISCLAIMER: I am not an expert, I am just some guy. My experiment is probably flawed and your results my vary. I have skied hundreds of days on both mount types without issues.
