U washer DIN 6340 — Washer for M16 screws, 17 mm bore (AMF)

A U washer DIN 6340 engineered for M16 screws with a 17 mm central bore, designed to ensure reliable load distribution and consistent fit in industrial fastening applications

• DIN 6340 standardised U washer
• For M16 screws, 17 mm bore
• 45 mm outer diameter, 6 mm thickness

Improved bearing and reduced stress on threaded connections

The DIN 6340 specification ensures a consistent geometry that benefits load-bearing joints. With an inner bore of 17 mm and a thickness of 6 mm, the component increases the contact area around the fastener head or nut, which reduces localised pressure and the risk of material deformation. In practical terms, this means longer service life for the joint and fewer re-tightening cycles. The combination of prescribed dimensions and standard compliance facilitates predictable performance in repetitive assembly processes, improving process reliability across production runs.

Predictable fit for easier assembly and inventory control

A defined outer diameter of 45 mm and precise bore tolerances allow for interchangeability in maintenance and production settings. By keeping dimensions standardised, the washer simplifies part selection during machine servicing and reduces downtime caused by mismatched components. The clear dimensional data supports procurement and storage planning: replacement parts are easily identified by their standard, diameter and thickness, so workshop and inventory management benefit from reduced complexity and faster turnarounds.

Versatile use across industrial fastening tasks

This U-shaped washer is suitable for a broad range of bolted assemblies where bearing surface and stabilisation are required. The washer’s geometry helps align the fastener, preventing pull-through in softer substrates and supporting clamping forces in steel or structural connections. For technicians and engineers, the part offers a straightforward solution when a standardised bearing washer is needed for M16 fasteners. The U washer DIN 6340 is thus a practical component for repair, retrofit and new-build applications where conformity and repeatable behaviour are priorities.

Selection advice and compatibility considerations

When specifying a washer, match the bore to the fastener’s shank; the 17 mm bore provides clearance for M16 threads while maintaining guidance for the bolt. The 6 mm thickness contributes stiffness under compressive load and assists in maintaining clamp force distribution. Note that material and surface treatment are not specified here; selection should consider corrosion resistance and electrical isolation requirements where applicable. For exact compatibility with a specific assembly, confirm material pairing and any coating needs before final selection.
