Spring washers are used to prevent loosening, flat washers have no relaxation function, that is, flat washers only increase the contact area, and spring washers can prevent loosening.
Flat pads: just increase the surface area to prevent damage to the mounted parts of the soft substrate or to block the holes.
The difference between a spring washer and a flat washer is edited by voice:
Spring washer can play a loose, increase the function of pretightening force, and flat washer does not have this function, it can be used to increase the fastening contact area, prevent the friction between the bolt and the workpiece, protect the surface of the connector to prevent scratching the workpiece surface when the bolt and nut tighten.

But some important connections, such as mainly rely on compression friction to transfer power, is not the use of spring pads, with the reduction of connection rigidity, the accident is easy. You don’t need a spring washer. When the strength of the connecting piece is low, the flat pad or flange bolt is used to increase the contact area. When there is vibration, pulse, and the temperature of the medium, the spring pad must be used.

Spring Lock Washer (Type 1)

Spring pad: After locking, use the elasticity of the spring pad to prevent loosening

Frequently Asked Questions (FAQ)
Q1:
What is the primary difference between a spring washer and a flat washer?
A spring washer is designed with elasticity to provide tension and prevent fastener loosening caused by vibrations or thermal expansion. In contrast, a flat washer does not prevent loosening; it is used to distribute the load, increase the contact area, and protect the surface of the workpiece from scratching.
Q2:
When is it necessary to use a spring washer?
A spring washer should be used in applications subject to vibration, pulse loads, or frequent temperature variations, where connections are highly prone to loosening over time.
Q3:
What standard specifications do your spring washers conform to?
Our spring washers are manufactured to meet major international standards, including ASME/ANSI B18.21.1, DIN127A, DIN127B, and DIN7980.
Q4:
What materials and finishes are available for these washers?
We offer spring washers in C70, 65Mn, Stainless Steel, and B+ss. Available finishes include Plain, Zinc Plated (Clear, Blue, Yellow, Black), Black oxide, Nickel, Chrome, and Hot Dip Galvanized (H.D.G.).
Q5:
What are your bulk packaging details?
Our standard packaging includes bulk in cartons (<=25kg) with 36 cartons per wood solid pallet, or bulk in cartons of 9″x9″x5″ (<=18kg) with 48 cartons per wood solid pallet. Custom packaging can also be arranged based on your specific requirements.
Q6:
What is your supply capacity for these washers?
We maintain a strong supply ability of 500kgs for each specification, ensuring timely delivery for large-scale industrial projects.
