Frequently Asked Questions (FAQ)

Q What insert materials are standard, and can they be customized?

Standard inserts are made of conventional materials such as brass, steel, copper, and iron. Stainless steel and aluminum inserts can also be fully customized to meet your application specifications.

Q What does 'BD' stand for in the specifications table?

'BD' refers to the product's Bore Depth (measured in mm). While standard depths are listed in the table, customized bore depths can be provided upon request.

Q Are non-standard height sizes and screw lengths available?

Yes. While the attached table displays conventional models, non-conventional screw lengths (Type 2-4) and non-standard height sizes can be customized for your exact requirements.

Q What testing standard applies to the Nominal Voltage ratings?

The nominal voltage values (AC/DC) provided in the product specification tables adhere to the IEC 60355 testing standard. Custom insulator options are available for higher voltage demands.

Q Can the tightening torque be adjusted for higher mechanical load needs?

The tightening torque values listed represent standard installation torque limits. If your installation demands higher torque resistance, customized high-torque inserts can be configured.

Q How can I confirm dimensional tolerances and actual product color?

Actual performance parameters, dimensional tolerances, and visual appearance colors are subject to specific technical drawings. Please contact our support team to request final engineering drawings.
