SUPERBOLT® Flexnuts

Standard Range

General Description

SUPERBOLT® Flexnuts of the SX8 Series are able to flex elastically. Under load SUPERBOLT® Flexnuts flex out at the bottom and in at the top. This helps relieve stress concentrations and increases the fatigue life of the bolt. Therefore, SUPERBOLT® Flexnuts are used for applications where boltings are in danger of breaking due to fatigue.

SUPERBOLT® Flexnuts are reactive nuts only. They may not be torqued.

Applications:
Boltings with short clamping lengths

Available upon request:

inch threads (UN and Whit)
D > M160
other sizes and specials
anti-corrosion protection
special materials
