Frequently asked questions

Can I use these bolts for outdoor applications?

Yes, thanks to the electrolytically galvanized finish, these bolts are suitable for outdoor use. However, for applications in highly corrosive environments, the use of stainless steel bolts is recommended.

What size hex key do I need for these bolts?

For these M8 hexagon socket head bolts, you need a hex key with a width of 6 mm.

Are other lengths available in this series?

Yes, these hexagon socket head bolts are available in various lengths. Check the range to find the right size for your application.

Can I reuse these bolts?

Reusing bolts is generally not recommended, especially in critical applications. Reuse may reduce the tensile strength, which can affect the reliability of the connection.

Are special nuts and washers required for these bolts?

It is recommended to use nuts and washers that match the strength class and size of the bolts. This ensures optimal and safe fastening.

How should I best store the bolts?

Store the bolts in a dry place and avoid exposure to moisture to maintain their corrosion-resistant properties.

Are these bolts suitable for use in wood?

Yes, these bolts can be used in wood constructions, provided the correct pre-drilling and nuts are used for a secure fastening.

What is the maximum tightening torque for these bolts?

The maximum tightening torque depends on the application and the material in which the bolt is used. Consult the technical specifications or a specialist for the correct tightening torque.

Are alternative finishes available?

Yes, in addition to the galvanized finish, hexagon socket head bolts are also available in stainless steel (A2) for applications requiring higher corrosion resistance.

Can I use these bolts with plastic materials?

Yes, these bolts can be used with plastic materials, but it is important to use the correct tightening torques to avoid damaging the plastic.
