The Flat Gasket is a high-performance washer designed to participate in the friction of moving parts and generate torque efficiently. Engineered with precise dimensions and optimized hardness, it ensures smooth rotation, strong connection, and long-lasting durability.
As part of the high carbon flat washers / high carbon steel washers / carbon steel washers series, the Flat Gasket is ideal for shafts, hinges, and precision hardware assemblies where rotational stability and operational reliability are essential. Its precise design and advanced surface treatments allow it to perform reliably under repeated friction and load.

Precision Engineering: Manufactured with tight dimensional tolerances (OD 1.7–24 mm, ID 0.82–12.05 mm, thickness 0.5–1.5 mm), ensuring consistent torque and friction performance (high carbon washers / carbon washers / flat gasket).
High Load Capacity: Optimized hardness (HRC 43–50) allows the gasket to withstand repeated compression and rotational forces without deformation, providing a strong and stable connection for long-term use.
Consistent Friction Control: Actively participates in the friction of moving parts, generating torque while maintaining smooth rotation and tactile operational feel.
Versatile Compatibility: Works seamlessly with other washers (high carbon flat washers / high carbon steel washers / flat gasket flat seal / gasket ring) for anti-loosening, vibration absorption, and load distribution.
Wide Application Range: With multiple surface treatments (Environmental Nickel, Chemical Nickel, Black Oxide, Zinc-Nickel Alloy), the Flat Gasket maintains reliable performance across micro to medium shaft applications, precision instruments, and hardware assemblies.

Flat Gaskets are widely used across consumer electronics, home appliances, automotive, and medical devices, where friction control, torque transmission, and durability are essential:
Consumer Electronics: Used in micro-motors and rotary shafts of printers, cameras, and smart appliances to maintain smooth rotation and consistent torque.
Home Appliances: Applied in hinges, rotary knobs, and adjustment mechanisms in kitchen devices, washing machines, and HVAC units for stable operation and enhanced tactile feel.
Automotive: Integrated into control knobs, steering column adjustments, and gear shifter assemblies to improve torque response, reduce backlash, and extend component life.
Medical Devices: Installed in small precision instruments such as infusion pumps, diagnostic devices, and surgical tools to ensure smooth operation, reliable friction, and long-term reliability.
How to Use:
Select the appropriate ID for the shaft and match OD/thickness.
Install directly on the shaft or combine with other washers for torque control.
Suitable for dry or lightly lubricated environments; surface treatment improves corrosion resistance.
Proper installation ensures smooth rotation, stable connection, and extended service life by providing even torque distribution and preventing wear.
Q1: what does a flat washer do
A: A flat washer distributes pressure evenly over a surface, reduces wear between the fastener and the material, and helps prevent loosening of connections.
Q2: what is a flat wash
A: A flat washer is a thin disk with a hole in the center that supports bolts, screws, or shafts, providing a smooth bearing surface and reducing friction during assembly.
Q3: Can custom sizes or surface treatments be provided?
A: Yes, we support customization for OD/ID/thickness and surface treatments, including Environmental Nickel, Chemical Nickel, Black Oxide, and Zinc-Nickel Alloy.
Q4: What is the MOQ?
A: No strict minimum order quantity. Stocked items are ready for immediate shipment for samples, small orders, or bulk supply.
Q5: How is quality ensured?
A: Material inspection, heat treatment, hardness testing (HRC 43–50), and dimensional tolerance control ensure reliable performance and long service life.
