Comparison of locking disc spring washers and lock washers | |
| Locking disc spring washer | Lock washer with no DIN standard |
| + Twice as secure: spring-secured friction fit and positive locking + Minimal tightening torque distribution + Application range up to approx. 350°C + Reusable + Protection of the counter surface; no turning | Without a DIN standard, lock washers become a safety risk! - Very high tightening torque distribution - Only suitable for locking screws 5.8 - In the worst case scenario, lock washers can wear through surfaces and thereby promote a drop in the preload force. - No protection against unscrewing - Lock washers are not reusable - Lock washers tend to expand (risk of breakage) - They turn during tightening and loosening -> This damages the surface/counter surface |
