The flat washer is a precision component placed between moving parts, evenly distributing load while reducing wear. It participates in friction during operation, generating controlled torque for smooth motion and reliable mechanical performance.
Even Load Distribution
Flat washers help spread the load of a fastener evenly over a larger surface area, preventing damage to the material and extending the lifespan of assemblies
Friction Reduction
By reducing direct contact between the fastener and the material, flat washers minimize friction during tightening, ensuring smoother and more consistent assembly.
Surface Protection
They protect the underlying surface from scratches, dents, or wear caused by the turning of nuts or bolts, maintaining the integrity and appearance of the workpiece.
Secure Fastening and Alignment
Flat washers help maintain the stability of fastened joints and can compensate for minor surface irregularities or misalignments, ensuring a reliable and durable connection.

The flat washer is placed between the screw head (or nut) and the surface of the part being fastened.
This positioning ensures that the load is evenly distributed and the surface is protected.
If used together with a spring washer, the correct order is:
Bolt head → Flat washer → Spring washer → Nut
A flat washer serves several important purposes:
It spreads the load of a bolt or nut over a larger area, reducing surface pressure.
It prevents damage or deformation of the material being fastened.
It helps reduce friction during tightening and improves the life of both the fastener and the assembly.
A flat washer is a thin, flat, round piece of metal or plastic with a hole in the center, used to distribute the load of a threaded fastener such as a bolt or screw. It provides a smooth bearing surface, prevents surface damage, and improves the stability of the fastening connection.
Make it easy for customers to make shafts and apply them to more fields.
