J-System hex bolt DIN933 PA6.6 M6 x 30

Plastic bolts are chosen when metal is not the best solution, for example because a connection must not corrode or must not conduct electricity. Below you can read what the product code means, what this type of bolt is used for, and what to check before ordering.

What do DIN933, PA6.6 and M6x30 mean?

DIN 933 is the standard for hex bolts with full thread, so thread over the entire shank length. Such a bolt is often used directly in a tapped hole or together with a nut. PA6.6 is the material: polyamide 6.6. M6x30 indicates the size, with a thread diameter of 6 mm and a length of 30 mm. The head is not included in the length.

When do you choose a hex bolt made of PA6.6?

Polyamide is lighter than steel and does not rust. It does not conduct electricity, which makes the material suitable for applications near live parts. On the other hand, a plastic bolt is less strong than a steel or stainless steel bolt. Therefore use it for light to moderate loads and not for structural connections that must carry a lot of force. Also do not overtighten a plastic bolt, as the thread can then be damaged.

What should you check when ordering this hexagon bolt M6x30?

First check whether the thread size and length match your tapped hole or nut. Then determine whether PA6.6 suits the conditions, such as temperature, moisture and load. If you use a nut or washer, choose one in the matching size M6. If you are unsure about the combination, please contact Proffix. Ordering can be done by phone or email, and products that are not in stock can be sourced for you by Proffix.

Frequently asked questions

What is the difference between DIN 933 and DIN 931?

DIN 933 is a hexagon bolt with thread along its full length. With DIN 931, the bolt has a section without thread, the so-called shank.

Is a PA6.6 bolt as strong as a steel bolt?

No, polyamide is less strong than steel. The bolt is intended for light applications where corrosion resistance or electrical insulation is more important than strength.

Which nut fits an M6 bolt?

A bolt with thread size M6 requires a nut of the same size, M6. Also make sure the thread pitch matches.
