Torque To Yield (TTY) Bolts are a one-time-use fastener, designed to stretch, during the torquing process. They act like springs for consistent, precise clamping force in critical joints like cylinder heads. They undergo permanent elongation and must be replaced with new ones after removal. Consequently reusing them can lead to improper tension, damage, or failure.
