How much angular deviation can spherical washers compensate?

All-spherical, two-piece washers automatically adjust under compression for compensating angular deviations up to 4 degrees.

What is the significance of male and female components in a spherical washer?

When the male and female components nest, they swivel slightly to compensate for uneven surfaces & tolerance variations.

What is the advantage of compensating angular deviations?

Compensation of angular deviations creates a parallel plane between the inner face of the nut and the inner face of the bolt head. This allows uniform distribution of load over the complete inner contact surface area.

What is the nature of tolerance of the concave and convex components of these spherical washers?

The concave component has a positive tolerance while the convex part has a negative tolerance.
