Flange Screw

Screws to the DIN 967 standard are fitted with a flange. The hemispherical head with a press washer ensures secure fixation when tightened, preventing self-loosening of the screw under vibration.

The flange provides more even load distribution across the material surface and prevents the formation of cracks.

Applications

Self-loosening weakens the reliability of a joint, which is dangerous in critical connections. A flange screw is held securely in the material: serrations on the underside of the flange grip the surface, preventing it from unscrewing. Such fasteners are used in various fields:

• Construction and structural assembly. The products can be installed in metal or wood.
• Industrial manufacturing. Such parts are used in machine building, machine tool assembly and various equipment operating in demanding conditions.
• Furniture manufacturing and other industries.

Features

The products are made of durable steel, with or without zinc coating; corrosion protection is mandatory for use in demanding conditions. Flange screws eliminate the need for additional press washers — the flange alone provides a secure fixation.
