DIN6319 Spherical Washer Convex And Concave Self Aligning Washer

A high-precision industrial fastening component supplied by Ningbo Gangtong Zheli Fasteners Co., Ltd., this series is designed to resolve common assembly challenges in heavy-duty bolt connections. Unlike ordinary flat washers, the matched C-type convex and D-type concave structure can automatically adjust angles and balance stress during equipment installation. DIN6319 Spherical Washer Convex And Concave Self Aligning Washer effectively avoids bolt bending and loosening triggered by eccentric load, improving the safety and service life of mechanical connection structures. Complying with German DIN industrial standards, it boasts precise tolerances and great interchangeability for various fixture and bolt systems.

Product Standard & Complete Specification Parameters

Industrial assembly often faces misalignment issues, so selecting fasteners with angle compensation capability matters greatly. The table below lists core standard parameters for reference.

Item	Standard Specification	Technical Requirement
Product Standard	DIN6319	German Industrial Standard
Product Structure	C Convex + D Concave Pair	Complete self-aligning matching set
Allowable Correction Angle	3-4°	Compensate assembly angle deviation
Size Range	M6-M64	Full size customization supported

For heavy-load mold and machinery projects, DIN6319 Spherical Washer Convex And Concave Self Aligning Washer is widely adopted to offset inclined mounting surfaces and uneven fitting planes.

Product Material & Surface Treatment Options

Raw material selection directly decides the washer’s performance under different working environments. We source raw steel from reliable large mills to guarantee stable mechanical performance. The material and surface treatment options are shown in the table below.

Material Type	Surface Treatment	Performance & Application Scenarios
C45 Carbon Steel	White Blue Zinc Plated (Min 5μm)	Uniform plating, excellent anti-rust performance, suitable for outdoor and conventional industrial equipment, the most popular foreign trade style
C45 Carbon Steel	Black Oxide with Anti-rust Oil	Smooth fitting surface, no glare, tight assembly, suitable for internal connection of molds and mechanical equipment
A2/A4 Stainless Steel	Bright Polished Finish	Natural anti-corrosion, rust-proof and oxidation-resistant, suitable for humid, coastal and corrosive environments

C45 carbon steel will go through heat treatment to gain high compression resistance, while stainless steel versions feature great weather resistance. With these diversified choices, DIN6319 Spherical Washer Convex And Concave Self Aligning Washer can adapt to light load, heavy load and corrosive working conditions.

Core Product Features & Advantages

Precision forging and fine grinding are applied for all parts, delivering smooth spherical contact surfaces for convex-concave fitting. The self-aligning design can compensate 3~4 degrees of assembly angle error, reducing stress concentration on bolts caused by tilted installation.

Compared with regular washers, DIN6319 Spherical Washer Convex And Concave Self Aligning Washer lowers the risk of fastener failure under continuous vibration and heavy pressure. Low failure rate helps clients cut equipment maintenance cost and keep mechanical systems running steadily.

Wide Application Range

Many industrial scenarios require reliable angle correction for bolt joints. This washer set fits precision plastic molds, hardware stamping molds, tooling fixtures, hydraulic systems, automated production lines and steel structure projects.

For heavy engineering machinery and industrial supporting facilities, DIN6319 Spherical Washer Convex And Concave Self Aligning Washer acts as an essential auxiliary fastener to optimize connection stress and stabilize assembly.

FAQ

Q1: What is the difference between DIN6319 and common flat washers?

A1: DIN6319 Spherical Washer Convex And Concave Self Aligning Washer adopts matched convex and concave curved surface design. It can compensate the angle deviation during assembly, while ordinary flat washers cannot adjust tilted installation planes.

Q2: Can I get samples for testing before bulk order?

A2: Yes, sample service is available. We can supply samples of different materials and surface treatments for your performance verification.

Q3: What is the minimum order quantity?

A3: MOQ depends on sizes. Regular sizes have low MOQ, customized sizes will be confirmed upon discussion.

Q4: How long is the service life for black oxide DIN6319 washers?

A4: Black oxide parts are suitable for indoor non-corrosive environment. If used in humid outdoor conditions, white blue zinc plated version is recommended for better rust resistance.
