Standard:DIN6796(Current versionDIN6796-2009Conical disc spring washers specially designed for bolt connections

✅ structural principle

The overall disc is a smooth conical disc with no rolling teeth on both sides. When tightening the bolt, the disc pad is flattened, continuously outputting stable axial elastic force; Used to compensate for the attenuation of bolt pre tightening force, offset the tensile loss caused by creep, thermal expansion and contraction, and contact surface settlement.

The core isElastic compensationIt is not about anti-slip through tooth meshing.

✅ material and heat treatment

1. 65MnSpring steel (mainstreamQuenching and temperingHRC42~48Adaptation8.8/10.9 Grade high-strength bolts; The surface can be selected as blackened, galvanized or Dacromet (high salt spray).

2. 60Si2MnA / 50CrVA：Under heavy load and high temperature conditions, the fatigue performance is better

3. SUS304 / SUS316LStainless steel：Corrosion resistant environment, low hardness, weaker bearing capacity than spring steel

✅ range of specifications

Thread matching M2~M125，Regular spot goods M3~M30; It can be used as a single piece orSuperposition (increase force), counterposition (increase stroke)Multiple pieces are used together to flexibly adjust the elasticity and deformation Tiktok

✅ Product features

· Pure elasticity maintains preload forceToothless, it will not damage the surface of the workpiece，Aluminum and plastic parts are available（VS NFE25-511)

· Compact size, high elasticity, replacing ordinary open spring pads, better fatigue resistance

· Support multiple combinations to adapt to different load requirements

· ⚠ ️Weak pointIt has no occluding teeth and has a weak ability to resist lateral alternating vibration，Only suitable for connections primarily subjected to axial loads, not recommended for use alone in strong lateral vibration scenarios DIN6796bugel.kz

✅ application scenarios

Construction machinery, motors, fans, hydraulic equipment, gearboxes, ordinary mechanical equipment, pre tensioned connections of steel structures; Suitable for: thermal expansion and contraction, contact surface creep, bolt connections that require continuous compression.

✅ Installation points

1. ConicalThe convex side faces the nut and the concave side is in contact with the workpiece

2. Recommended matching bolt grades8.8 or higherGrade; Lower than8.8Grade bolts are prone to compression and elastic failure Link11

3. When stacking multiple pieces, pay attention to the direction, stack them in the same direction, and stack them in the opposite direction
