Concrete and Masonry Screw, Heco-Multi-Monti-plus, Hex Head with Combined Washer

Product Details

Is the Heco MM+ Hex Hd+Washer SW13 D10x140mm suitable for concrete and masonry?

Yes. This is a concrete and masonry screw designed for fixing into mineral substrates such as brickwork and concrete. The long length of 140 mm makes it especially useful when you need solid embedment and secure fixing in thicker structures.

What size do I need, and how do the 10 mm thread and 140 mm length affect installation?

Choose it based on your required fixing depth and load needs. The screw has a thread diameter of 10 mm and a length of 140 mm. Make sure the embedment and overall length suit your wall thickness and the part you are fastening, as using the wrong length can reduce holding power.

Does the screw include an integrated washer, and what is its size?

Yes. The product name indicates it includes a built in washer, helping spread the load under the screw head. The washer diameter is 19 mm, which can be beneficial when fastening materials where you want a wider bearing surface.

Which drive bit do I need to fit this screw?

You will need an SW13 drive. This size corresponds to the head for tightening. Using the correct drive size helps avoid rounding the head and makes installation faster and more consistent.

Why is the screw described as bright carbon steel, and does it relate to corrosion resistance?

Bright carbon steel is commonly used for strong, durable fixings. For outdoor use or damp environments, always consider the exposure conditions and any relevant project requirements, as corrosion resistance can depend on the exact environment and any additional protective systems used.

How many screws should I plan to use for a typical masonry fix?

It depends on the load and the application. For concrete and masonry screws, the correct number and spacing is usually determined by the weight of the item being fixed, the substrate condition, and manufacturer guidance for the system. If you are unsure, you can match your layout to similar fastening patterns used for comparable 10 mm masonry screws.
