Concrete Screws

Concrete Screws, also known as Concrete Anchor Screws or Concrete Fixing Screws, are designed for fastening structural and non-structural components directly to concrete.

SANN MUO concrete screws are used to connect components such as steel plates, timber trusses, steel trusses, and other construction elements to reinforced concrete and concrete walls.

Compared with conventional anchor systems, concrete screws can simplify the installation process by using a pre-drilled hole and mechanical thread engagement directly into the concrete.

SANN MUO offers both Light-Duty Concrete Screws and Heavy-Duty Concrete Screws for different concrete fastening requirements.

Concrete Screw Product Range

SANN MUO currently lists these two products within the Concrete Screws product family.

What Are Concrete Screws?

A Concrete Screw is a mechanical fastening screw designed to secure components directly to concrete.

Unlike conventional expansion anchors, concrete screws use threads that engage with a pre-drilled hole in the concrete.

This allows installers to fasten components without using a separate traditional anchor assembly.

Typical applications include fastening:

• Steel plates to concrete
• Timber trusses to concrete
• Steel trusses to concrete
• Construction components to concrete walls
• Structural and non-structural components to reinforced concrete

SANN MUO specifically identifies steel plate, timber truss, and steel truss as examples of components that can be connected to reinforced concrete.

Concrete Screws vs. Traditional Anchors

Key Advantage

The major advantage of a concrete screw is the ability to combine the screw and anchoring function into one fastening component, reducing the number of installation steps.

This is consistent with SANN MUO's current description that concrete screws can save installation processes compared with conventional anchors.

Light-Duty Concrete Screws

Light-Duty Concrete Screws are designed for lighter concrete fastening applications.

They are suitable when the connected component does not require the higher load capacity associated with heavy-duty concrete anchoring.

Typical applications may include:

• Light construction components
• Non-structural components
• Fixtures
• Light steel components
• General concrete fastening

For specific load-bearing applications, the appropriate screw size, concrete strength, embedment depth, and installation conditions should be evaluated before selection.

SANN MUO lists Light-Duty Concrete Screw as one of its two primary Concrete Screw products.

Heavy-Duty Concrete Screws

Heavy-Duty Concrete Screws are designed for applications requiring higher fastening performance.

They are suitable for connecting heavier components to concrete, including applications involving:

• Steel plates
• Steel structures
• Timber trusses
• Steel trusses
• Structural construction components

SANN MUO specifically lists Heavy-Duty Concrete Screw within its Concrete Screws product family.

For structural applications, screw diameter, embedment depth, concrete strength, edge distance, spacing, and installation torque should be evaluated according to the project requirements.

For heavier components or higher fastening requirements:

Concrete Screws for Steel Plate to Concrete

Concrete screws can be used to connect steel plates to reinforced concrete.

This type of connection is common in construction where a steel component needs to be fixed directly to a concrete wall, floor, foundation, or other concrete structure.

The appropriate concrete screw should be selected according to:

• Steel plate thickness
• Concrete strength
• Required load
• Screw diameter
• Embedment depth
• Edge distance
• Installation torque

Steel plate-to-concrete fastening is specifically identified in SANN MUO's Concrete Screw product description.

Concrete Screws for Timber Truss

Concrete screws can also be used to connect timber truss components to reinforced concrete structures.

This is particularly relevant in construction systems where a timber structure needs to be securely connected to a concrete wall or foundation.

The selection of the concrete screw should consider:

• Timber connection design
• Concrete strength
• Required load
• Embedment depth
• Screw diameter
• Edge distance

SANN MUO specifically lists timber truss as one of the applications for its Concrete Screws.

Concrete Screws for Steel Truss

Steel Truss to Concrete is another important application.

Concrete screws can provide a direct fastening method for connecting steel truss components to reinforced concrete structures.

Typical applications include:

• Steel truss
• Steel frame
• Structural steel components
• Steel plates
• Concrete walls

This application is directly identified on SANN MUO's Concrete Screws category page.

Concrete Screw Installation

Concrete screws generally require a pre-drilled hole before installation.

A typical installation process is:

1. Position the component

Place the steel plate, timber component, truss, or other element against the concrete.

2. Drill the pilot hole

Drill a hole into the concrete according to the required screw diameter and installation specification.

3. Clean the hole

Remove concrete dust and debris where required.

4. Install the concrete screw

Drive the screw into the pre-drilled concrete hole using the appropriate installation tool.

5. Verify fastening

Check screw seating, component contact, and installation torque according to the application requirements.

Concrete Screws for Structural and Non-Structural Applications

Concrete screw applications can be divided into two major categories.

Structural Applications

Examples include:

• Steel truss to concrete
• Timber truss to concrete
• Steel plate to concrete
• Structural components to reinforced concrete

Non-Structural Applications

Examples include:

• Fixtures
• Light construction components
• General concrete fixing
• Non-load-bearing components

The appropriate product must be selected according to the actual load and engineering requirements.

SANN MUO's existing product information explicitly describes concrete screws as being used for both structural and non-structural elements.

Concrete Screw Material and Customization

For the detailed product specifications, SANN MUO currently lists concrete screw products using materials including:

• Carbon Steel 1022
• Carbon Steel 1018
• Alloy Steel 10B21
• Alloy Steel 10B33

The related Concrete Screw product pages list sizes from #8–#14 and M4–M20, with lengths from 5"–12" and 100–300 mm, subject to the individual product specification.

SANN MUO can manufacture according to:

• DIN
• IFI
• ISO
• ASTM
• ASME
• Customer drawings
• Customer samples

Customized Concrete Screws

SANN MUO provides customized screw manufacturing for customers requiring specific dimensions, materials, thread configurations, or performance requirements.

Customization may include:

• Screw diameter
• Screw length
• Head design
• Thread design
• Material
• Surface treatment
• Coating
• Point configuration
• Custom packaging

Customers can provide an existing screw sample or technical drawing for evaluation.

For concrete applications, it is particularly useful to provide:

• Concrete strength
• Connected material
• Required load
• Screw diameter
• Required embedment
• Existing screw sample
• Installation tool
• Installation torque

Concrete Screws for B2B Construction Buyers

Concrete screws are commonly purchased by:

• Construction fastener distributors
• Building material suppliers
• Structural component manufacturers
• Steel fabricators
• Timber truss manufacturers
• Construction contractors
• Hardware distributors

For B2B buyers, the correct product should not be selected based only on screw unit price.

The total fastening cost should also consider:

Screw Cost + Installation Time + Labor Cost + Installation Equipment + Rework Risk

A concrete screw that simplifies installation may help reduce total installation cost, particularly in markets where construction labor is expensive.

Second Source for Concrete Screws

If you are currently purchasing concrete screws from another supplier, SANN MUO can evaluate your existing product as a potential second-source supplier.

You can provide:

• Existing screw sample
• Technical drawing
• Concrete strength
• Connected material
• Required load
• Screw diameter
• Screw length
• Embedment depth
• Coating requirement
• Installation method

SANN MUO can then evaluate the product according to the actual application rather than simply comparing unit prices.
