Set Screw DIN 913

The set screw with flat point and hex socket is manufactured in accordance with the German standard DIN 913. Analogs: set screw DIN 551 with flat point and slot, fasteners ISO 4026 and GOST 11074-93 (with hex socket). The screw’s shape allows fastening several identical fasteners to each other. Thread diameter: M1.4–M24.

Screws of this series are made of high-strength hardened steel, property class 45H, zinc-plated steel, and stainless steel grades A1–A5. The fastener is selected based on operating conditions. Under increased physical loads and exposure to aggressive environments, screws made of hardened steel are used — this material is resistant to corrosion, wear and temperature fluctuations, and is suitable for use in the Far North.

High-strength screws are practically not subject to damage during operation. They are used in aircraft and machine building, where the requirements for fastener quality and reliability are high.
