Carbon Steel DIN935 Hex Slotted Nuts

Product Overview

High-Strength Anti-Loosening Design

The DIN935 carbon steel hex slotted nut is a heavy-duty fastening nut produced by YPH in strict accordance with DIN935/DIN937 standards, designed for high-vibration and high-load applications. Made of high-quality carbon steel, it is available in multiple strength grades including 4, 6, 8, and 10 to meet different load-bearing requirements. The hexagonal structure ensures stable torque transmission during installation, and the slot design on the top allows matching with cotter pins to achieve a reliable anti-loosening effect. With three surface treatment options of zinc plating, blackening, and yellow zinc plating, it not only enhances corrosion resistance but also adapts to different working environment conditions. It is widely recognized in the heavy machinery and transportation industries for its high strength and excellent anti-loosening performance.

Technical Specifications

Key Advantages

Multi-Grade Strength Options

Strength grades ranging from 4 to 10 cover different load scenarios, from light-duty equipment to heavy-duty machinery, with strong adaptability.

Reliable Anti-Loosening Performance

The top slot design cooperates with cotter pins to lock the nut and bolt, preventing loosening caused by vibration and ensuring long-term use safety.

Diversified Surface Treatments

Zinc plating provides basic corrosion resistance, blackening enhances wear resistance, and yellow zinc plating achieves higher anti-rust levels, meeting different environmental demands.

Application Scenarios

Heavy Machinery Manufacturing

Used for fixing key components of construction machinery, mining equipment, and agricultural machinery, withstanding high loads and strong vibrations.

Transportation & Automotive Industry

Applied in the assembly of truck chassis, railway vehicle components, and ship deck equipment, ensuring the safety and stability of vehicles and vessels during operation.

Architectural & Engineering Projects

Suitable for connecting steel structures of bridges, high-rise buildings, and power transmission towers, providing reliable fastening force for large-scale engineering.

Usage Guidelines & Purchase Information

Usage Guidelines

Select the corresponding strength grade according to the actual load-bearing requirements; for high-vibration environments, must match with cotter pins for anti-loosening.

Use a standard hexagonal wrench for installation; ensure the slot is aligned with the bolt pin hole after tightening, then insert the cotter pin and bend the ends.

Regularly inspect the surface treatment status; if rust occurs, timely carry out anti-rust maintenance to extend the service life.
