Product Details

What does the size M3.5 x 7.5 mm mean?

The M3.5 refers to the screw thread size, and 7.5 mm is the thread length. This helps you choose the correct screw for the panel thickness and the fitting requirements of your connecting application.

Is this connecting screw suitable for cross profile panels?

Yes, this NPS connecting screw is designed for cross profile applications. If your system or panel connector is specified for cross profile, this screw size should match the intended fixing method.

How many screws are needed per cut piece panel?

For ordering guidance, the product information specifies 2 screws are required per cut piece panel. The order reference also notes that you might order 1 piece, depending on how many panels you are fitting.

Will it fit the correct thread diameter for my existing parts?

This screw uses a 3.50 mm thread diameter, so it is intended to work with components that accept an M3.5 connecting screw. Checking the mating part specification before purchase will help avoid mismatch issues.

What finish should I expect on this screw?

This model is supplied as steel with a brass coating. The coating is typically used to provide improved appearance and corrosion resistance compared with plain steel, depending on the environment where it is installed.

What are the correct tools for installing an M3.5 connecting screw?

Because this is a connecting screw for use in systems with profile fittings, you will normally need the appropriate screwdriver or driver tip that matches the screw head style. If you are replacing existing screws, use the same type of driver that fit your current fasteners for the smoothest installation.

What should I confirm before buying this part number 551.90.991?

Before ordering, confirm your required specification: connecting screw for cross profile, M3.5 thread size, and 7.5 mm thread length. Selecting the correct part helps ensure proper engagement and a secure connection.
