The M10 AISI ANSI A4 80 SUS Stainless Steel Double Fold Self Locking Washer is a precision fastener designed to protect connected surfaces, prevent fastener loosening, and serve specialized purposes in demanding applications.
Washers are categorized into multiple types including flat washers, spring washers, anti-loose washers, and special purpose washers like sealing washers. Specific variants include:
- Flat washers (Class A, C, chamfered)
- Large washers (Class A, C)
- Spring washers (standard, light, heavy)
- Lock washers (internal/external tooth, serrated)
- Stop washers (single/double ear, outer tongue, round nut)
The self-locking mechanism consists of two washers with complementary surfaces - outer radial convex and inner bevel tooth. When assembled, these surfaces interlock to prevent loosening under vibration by creating lifting tension between the washers.
| Aluminum | Excellent thermal/electrical conductivity but requires careful processing due to softness |
| Titanium | Requires EDM machining with deionized water to control heat during processing |
| Steel | High strength material often processed with wire cutting machines for complex features |
| Brass | High tensile strength but requires slow cutting speeds due to softness |
| Automotive | High-strength applications in engines and heavy-duty components |
| Mechanical | Connecting mechanical parts, circuit boards, and transmission systems |
| Energy | Power generation equipment and transmission line fixtures |
| Construction | Building structures, shipbuilding, and petrochemical equipment |
Metal Washers: High strength and corrosion resistance for high temperature/pressure applications
Non-metal Washers: Excellent sealing and shock absorption for precision applications
Composite Washers: Combine strength of metal with sealing properties of non-metal materials
