Built for through-hole work, Flexnuts take a different approach: their reactive design spreads the bolt load across many threads, adding elasticity and keeping stress from concentrating in the first few. The result is lower stress build-up and a longer fatigue life for the bolt. Because Flexnuts are reactive nuts made to sit opposite our tensioners, they're never torqued directly to create preload. What they deliver: even load distribution across the bolt or stud threads under load, added elasticity in the joint, and extended fatigue life for the bolt or stud.
Superbolt developed the Flexnut for through-hole applications. Flexnuts bring the advantages of MJT-type elasticity to the reactive side of the joint.
Flexnuts are designed to flex out at the bottom and flex in toward the top of the nut. This distributes the bolt load along many threads, adds elasticity, and prevents stress concentrations in the first few threads.
