Stainless Steel Square Taper Washers

Angled Square Washers for Structural Connections and Surface Compensation

Stainless Steel Square Taper Washers use a square outer profile, central round hole and inclined bearing surface to compensate for angular differences between the fastener axis and a sloped supporting member.

Product Overview

Square Taper Washers are one-piece bearing washers with a square outside shape, central round hole and a controlled tapered section—one edge is thicker and the opposite edge thinner.

The inclined face compensates for non-parallel contact between a bolt head or nut and a sloped structural surface. Correct seating improves bearing contact and load distribution while reducing uneven edge contact; it does not increase bolt strength or replace structural design.

For purchasing, specify bolt size, d1 hole diameter, A square width, s thickness, t taper-height difference or required angle, material, application, quantity and drawing. Availability depends on the selected geometry and project requirement.

Taper Geometry, Angle Compensation & Load Distribution

Flat vs Tapered
Flat washers have parallel faces; taper washers have an inclined face for non-parallel connections.
Angle Compensation
The tapered face compensates for angular mismatch between fastener bearing face and supporting member.
Bearing Contact
Without correction, a nut or bolt head may seat mainly at one edge; the correct taper improves contact.
Fastener Alignment
The washer supports more even seating while the bolt remains aligned to the designed connection.
Taper Angle
Angle is selected from the structural member, drawing and project requirement; no universal angle applies.
Material Thickness
Thickness affects bearing behavior, strength and installation space.
Selection Limit
Final selection depends on structural design, bolt size, surface angle and load requirement.

Frequently Asked Questions

What is a Square Taper Washer?

It is a square washer with an angled bearing surface designed to compensate for non-parallel fastening surfaces.

What is the difference between a Flat Washer and a Taper Washer?

Flat washers have parallel surfaces; taper washers have an inclined surface for angular compensation.

Can Square Taper Washers be supplied in stainless steel?

Yes. VALTOR supplies 304/A2 and 316/A4 stainless options according to the required geometry.

Are Square Taper Washers standardized?

Some beveled styles use established references, but many projects require drawing-based geometry because the taper depends on the installation.

Can VALTOR manufacture custom Taper Washers?

Yes. Custom hole, width, thickness, taper angle, taper height and material are available.
