Round Flat Washer

A fundamental mechanical fastener accessory, the Round Flat Washer is designed to distribute the clamping force of bolts, screws, or nuts evenly across the surface of the connected workpiece. It prevents damage to the workpiece (such as scratches or deformation) caused by direct contact with fasteners, and ensures stable, secure connections by reducing pressure concentration.

Core Features

•Force Distribution: Spreads the load of fasteners to protect fragile or soft materials (e.g., wood, plastic, thin metal sheets).

•Connection Stability: Minimizes loosening caused by vibration or uneven surface contact.

•Versatility: Compatible with most standard bolts, screws, and nuts for universal use in various applications.

Key Specifications

•Materials: Available in metal (carbon steel, stainless steel 304/316, brass, aluminum) for durability and corrosion resistance; non-metal (rubber, nylon, PTFE) for insulation or vibration damping.

•Dimensions: Defined by inner diameter (ID, matching fastener shank size), outer diameter (OD), and thickness—customizable to meet ANSI, ISO, DIN, or customer-specific standards.

•Surface Finish: Options include zinc plating, chrome plating, hot-dip galvanizing (for enhanced rust resistance), or plain (for cost-sensitive, indoor applications).

Typical Applications

Ideal for use in electronics, automotive assemblies, construction, industrial machinery, household appliances, and HVAC systems—any scenario requiring reliable, damage-free fastener connections.

Precision-manufactured for consistent dimensions, the Round Flat Washer ensures perfect fit with fasteners and long-term performance in both indoor and outdoor environments.
