Beveled Washer

Product Introduction

• Standard Name: Beveled Washer / Tapered Washer.

• Common Names: Beveled Washer, Wedge Washer, Beveled Spacer.

• Product Definition: A specialized washer featuring an inclined working surface, specifically designed for steel structure connections. Its primary function is to be installed on the inclined flanges of structural steel such as I-beams and channel sections. It provides a level bearing surface for bolt heads and nuts, compensating for structural angles to ensure axial bolt loading. This prevents connection loosening or component deformation caused by uneven stress distribution.

Key Features of Beveled Washers

• Beveled Design: One side is beveled (common angles such as 10-15°), the other side is flat, used to

  compensate for non-parallel surfaces, ensuring bolts are perpendicular and loads are evenly distributed.

• Various Shapes: Commonly square beveled for easy anti-rotation and alignment; also available in round.

• Materials and Coatings: Commonly carbon steel or malleable cast iron, with hot-dip galvanized (HDG),

  zinc-plated (ZP), or solid finishes for corrosion resistance; hardened types conform to ASTM F436

  standards.

• Various Sizes: Inner diameter 1/4"-4" (M6-M100), larger outer diameter, often with structural-grade

  thickness.

• Advantages: Compensates for angular deviations, distributes loads, prevents material deformation,

  economical for structural connections.

Working Principle

• Placement: Beveled side facing the non-parallel surface, flat side facing the nut/head.

• Angle Compensation: The beveled side fills the gap, ensuring bolt perpendicularity and preventing

  loosening due to lateral stress.

• Pressure Distribution: Evenly distributes clamping force when torque is applied, preventing localized

  deformation or embedding.

• Protection and Stabilization: The coating provides corrosion protection through geometric compensation

  and area expansion.

Product Applications

• Steel Structure Engineering: Secures I-beams, C-grooves, or US standard beams/columns, compensating

  for natural non-parallelism.

• Buildings and Bridges: Beam-column connections or roof framing, ensuring even load distribution.

• Infrastructure: Pipe supports or railing fixation; galvanized version is suitable for outdoor use.

• Heavy Machinery: Assembles equipment bases or frames, preventing angular misalignment.

• Industrial Fixing: General structural projects, compatible with high-strength bolts (e.g., A325/A490).
