DIN 931 8.8 zinc UNC Hex head bolt with partial thread, inch thread

Overview

DIN 931 is a hex head bolt with a partial thread and UNC inch thread. This model differs from standard metric bolts because its thread follows the American system, ensuring compatibility with other inch-threaded components. The partial thread on the shank helps create an optimal connection while reducing the risk of stress concentration at the joint.

DIN 931 8.8 bolts have a strength class of 8.8, indicating high resistance to mechanical loads. They are available in various sizes, making them versatile for use in different structures. The bolt surface is zinc-plated, providing additional corrosion protection, which is especially important in humid or aggressive environments.

Applications

The DIN 931 8.8 hex head bolt with partial UNC inch thread is ideal for structures that require high strength and reliability. Strength class 8.8 provides excellent resistance to breaking and deformation, making it suitable for heavy machinery and industrial equipment.

This bolt has a zinc coating that protects against corrosion, which is particularly important in humid or aggressive environments. The partial thread allows convenient joining of parts, ensuring reliable fastening in structures where accuracy and stability are important. It is used in various industries, including construction, automotive manufacturing, and energy.

Alternatives

DIN 931 8.8 zinc UNC is a hex head bolt with a partial inch thread. It is manufactured according to a European standard, ensuring high strength and reliability in use. Strength class 8.8 indicates that the bolt can withstand significant loads, making it suitable for structures where high resistance is required.

This bolt has a zinc coating that provides additional corrosion protection, especially in humid conditions. When selecting alternatives, pay attention to the thread type: UNC (Unified National Coarse) has a specific pitch that differs from other standards, so it is important to choose components that exactly match the requirements of your project.
