DIN6340 Carbon Steel Fixture Flat Washer
DIN6340 carbon steel fixture flat washer is a heavy-duty fastening accessory designed for fixture systems, clamping applications, and mechanical assemblies requiring increased load distribution. The DIN6340 carbon steel fixture flat washer features a larger outer diameter and robust structure compared with standard flat washers, providing improved support and reduced surface pressure.
Manufactured from high-quality carbon steel, the DIN6340 carbon steel fixture flat washer offers excellent mechanical strength, wear resistance, and reliable performance in industrial tooling and clamping applications. It is widely used in machine fixtures, jigs, molds, CNC equipment, and mechanical assembly systems where strong and stable fastening is required.
Product Overview
The DIN6340 carbon steel fixture flat washer is engineered for heavy-duty clamping and positioning applications. Its enlarged bearing surface helps distribute tightening forces over a wider area, reducing deformation of workpieces and improving fastening stability.
Compared with conventional washers, the DIN6340 carbon steel fixture flat washer provides higher load-bearing capability and better support for fixture components. It is commonly installed together with bolts, screws, studs, and clamping elements in production equipment.
As a specialized industrial fastener accessory, it is widely selected by OEM manufacturers, machining workshops, tooling suppliers, and engineering companies.
