15mm Washer DIN 6340 For M14 Bolts, S5 D40 - AMF

Take advantage of the DIN 6340 conformity, precise 15 mm bore and direct compatibility with M14 fastenings for reliable seating and consistent load distribution in assembly operations. Order the AMF washer directly via Metav Werkzeuge or ask our consultants if further specification is required.

AMF U-washer DIN 6340, 15 mm bore — flat washer for M14 bolts

The AMF U-washer DIN 6340 is a standardised flat washer designed to provide secure seating and even load transfer for M14 bolts in industrial and mechanical assemblies.

• DIN 6340 standard compliance
• 15 mm precision bore
• Suitable for M14 bolts
• 5 mm solid thickness, 40 mm outer diameter

Consistent seating and load distribution for bolted joints

The washer is manufactured to the DIN 6340 dimensional and tolerance framework, delivering predictable mechanical behaviour in assemblies. As a flat washer, it increases the contact area under a screw head or nut, which reduces surface pressure on the joint and helps prevent indentation or loosening under cyclic loads. The 15 mm bore (D1) ensures a precise fit on M14 threaded parts, while the 40 mm outer diameter (D2) provides a stable bearing surface. These characteristics support longer service life of bolted connections and fewer rework operations in production environments.

Simple specification and installation reduce assembly uncertainty

With clearly defined dimensions — D1: 15 mm, D2: 40 mm, S: 5 mm — the component simplifies parts lists and quality control procedures. The standardised sizing allows straightforward substitution in repair and maintenance workflows without time-consuming fitting trials. Because the part is specified to established tolerances, planners and buyers can rely on consistent interchangeability across batches, which streamlines procurement and inventory management in workshops and industrial stores.

Suitable applications and practical benefits in production

The washer is intended for use wherever M14 fastenings require a stable seating plane: structural assemblies, machine frames, flanged connections and general plant maintenance. Its measured thickness of 5 mm gives a robust spacer function, while the defined bore reduces the risk of misalignment during installation. For engineers and fitters, the part functions as a small but critical device that helps achieve secure torque transfer and maintain joint integrity under vibration and regular operation.
