Product Description

Product Introduction:

Hex bolt is the authoritative technical standard for hexagonal head fully(half) threaded bolts, established by the German Association for Standardization (DGBAS). A key characteristic of these bolts is that the shank has a complete, continuous thread from start to finish (commonly known as "full thread" or "through thread"). It is one of the most commonly used and classic mechanical fasteners, widely applied across various industries due to its simple design, reliable performance, and easy installation. Bolts conforming to DIN 933/931 are widely recognized and used globally, especially in Europe and regions heavily influenced by the German industrial system.

Product Features:

Full(half) Thread Design:

The entire length of the shank is threaded, allowing the nut or internally threaded component to engage and tighten in any position.

Provides extremely high connection flexibility, particularly suitable for applications requiring adjustable clamping thickness or connection to multiple parts.

Standardized Geometry:

Strictly adheres to the DIN 933/931 standard, clearly specifying the hexagonal head width across flats, head thickness, thread length, and the relationship between the shank diameter and length.

Ensuring high product interchangeability and consistent quality.

High Strength and Performance Grades:

Typically manufactured from materials such as carbon steel and alloy steel, and heat-treated according to performance grades (e.g., 8.8, 10.9, 12.9).

Grade 8.8 is a commonly used high-strength grade, suitable for most general industrial applications.

Stainless steel (e.g., A2-70, A4-80) and other materials are also available to meet special requirements such as corrosion resistance and weather resistance.

Excellent Load-Bearing and Tensile Capacity:

The hexagonal head design provides a large wrench contact surface for easy application of high torque.

The combination of a full thread and high-strength material results in excellent performance under both axial (tensile) and lateral (shear) forces.

Ease of Installation:

Can be installed using standard open-end wrenches, box wrenches, socket wrenches, or power tools, making it suitable for a wide range of tools and situations requiring specific operating space.
