Spherical washers from SKF are designed to create an exact, parallel plane between the bolt head and the face of the nut. These washers automatically adjust and compensate for the angular deviation between the planes and prevent the bolt from bending.
Automatically compensates for angular errors
Evenly distributed bolt tension
Reduces bolt fatigue from bending bolts
Improved bolt stretch possible due to increased clamping length
Surface treated for protection in humid and harsh environments
Available in standard and low-profile (LP) versions
