Product Description

FLEXNUTS

Flexnuts have been specially developed for through-hole applications. Their reactive design distributes the bolt load along many threads, adds elasticity and prevents stress concentrations in the first few threads.
This helps relieve stress concentrations and increases the fatigue life of the bolt. Since Flexnuts are reactive nuts to be used opposite our tensioners, they are never torqued directly to achieve preload.
