Hexagon Bolts are created to DIN 931

Short Description:

Hexagon Bolts are created to DIN 931, and are a partially threaded fastener with a hexagon-shaped head that is usually fixed with a spanner or socket tool.

Hosting a machine thread, these bolts are suitable for use with either a nut or within a pre-tapped hole.
Materials can include various grades of Steel, including Grade 5 (5.6), Grade 8 (8.8), Grade 10 (10.9) and Grade 12 (12.9) with Zinc plating, Zinc and yellow, galvanising or self colour.

As standard, they are available in sizes from M3 to M64, with non-standard sizes and threads – such as UNC, UNF, BSW and BSF – all possible to order.

Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Minimum order quantities apply.

Features and Benefits

Hexagon bolts are a type of fastener that is designed with a six-sided head and a partially threaded shaft. DIN 931 is a technical standard that outlines the manufacturing requirements for hexagon bolts. These bolts are commonly used in various industrial and mechanical applications due to their strength, durability, and versatility.

One of the key features of hexagon bolts created to DIN 931 is their partial threading. Unlike fully threaded bolts, which have threads that run the entire length of the shaft, hexagon bolts only have threads on a portion of their length. This design allows the bolt to be securely fastened in place while still providing enough clearance for components to move when necessary.

Another important aspect of hexagon bolts is their six-sided head. This design offers several advantages over other types of bolts. Firstly, the hexagonal shape allows for easier tightening and loosening with a wrench or socket. Secondly, the larger surface area of the head distributes the force of tightening over a wider area, reducing the likelihood of damage or deformation.

Hexagon bolts created to DIN 931 are available in a wide range of sizes and materials, making them suitable for a vast array of applications. They are commonly used in construction, automotive, and industrial machinery, as well as in household and DIY projects. The combination of their strength, durability, and ease of use makes hexagon bolts an essential component in many types of machinery and equipment.

In summary, hexagon bolts created to DIN 931 are designed to provide a secure and reliable fastening solution for a variety of applications. Their partially threaded shaft and six-sided head offer a range of benefits, including ease of use, increased strength and durability, and versatility. These bolts are an essential part of many types of machinery and equipment, and their popularity is a testament to their quality and effectiveness.
