Type 17 Point Wood Screws

Wood Screws Designed to Reduce Timber Splitting and Improve Fastening Performance

SANN MUO Type 17 Point Wood Screws are designed for applications where controlled penetration and reduced timber splitting are important.

The Type 17 cutting point cuts wood fibers into smaller pieces as the screw enters the timber. Its cutting grooves help collect and remove sawdust during installation, reducing the tendency of timber to crack or split.

For applications requiring additional holding performance, a High-Low Thread configuration is available. The high thread cuts deeper into the wood while the low thread increases contact with the substrate, helping provide stronger grip and improved resistance to pull-out and vibration loosening.

Type 17 Wood Screws are suitable for timber-to-timber fastening, light sheet-to-timber fixing, roofing, decking, and general wood construction applications.

Type 17 Point Designed for Timber

The defining feature of a Type 17 screw is its specialized point design.

Unlike a conventional sharp screw point, the Type 17 point incorporates cutting grooves that help cut and manage wood fibers during installation.

As the screw penetrates the timber, the cutting action helps break wood fibers into smaller pieces and assists in removing sawdust from the drilling path.

This design is particularly useful when fastening close to the edge of timber, where excessive material displacement can increase the possibility of splitting.

Key Benefits of the Type 17 Point

• Helps reduce timber splitting and cracking
• Cuts wood fibers into smaller pieces
• Helps collect and remove sawdust
• Improves screw penetration into timber
• Reduces installation resistance
• Suitable for fastening close to timber edges
• Supports efficient timber-to-timber installation

High-Low Thread for Increased Grip

Type 17 Wood Screws can be combined with a High-Low Thread design for applications requiring increased grip and fastening performance.

The high thread cuts deeper into the timber, while the low thread increases contact with the substrate.

This geometry leaves a larger volume of wood material between the threads and helps create a stronger mechanical grip.

High-Low Thread Advantages

Deeper Thread Engagement
The high thread penetrates deeper into the timber to establish strong thread engagement.

Increased Contact Area
The low thread increases contact between the screw and the wood substrate.

Stronger Grip
The combination of high and low threads helps improve the screw's holding performance.

Pull-Out Resistance
The thread configuration is designed to increase resistance to pull-out forces.

Vibration Resistance
The increased grip can help improve resistance to loosening caused by vibration.

Type 17 Wood Screw Applications

Type 17 screws are primarily designed for wood fastening applications where the screw needs to penetrate timber efficiently while minimizing damage to the wood.

Timber-to-Timber Fastening

Suitable for joining timber components where reducing splitting during installation is important.

Decking Applications

The Type 17 point can be used for timber decking applications where efficient penetration and reduced cracking are desirable.

Roofing Applications

Suitable for selected wood-based roofing applications and fastening components to timber substrates.

Light Sheet-to-Timber Fixing

Can be used to fasten light sheet materials to timber where the primary substrate is wood.

Wood Construction

Suitable for general wood construction, timber assembly, and woodworking applications.

Edge-Fastening Applications

The Type 17 point is particularly useful when screws need to be installed relatively close to the edge of timber and minimizing splitting is important.

Type 17 Point vs. Conventional Wood Screw Point

The main advantage of a Type 17 screw is its specialized cutting action during installation.

The actual fastening performance depends on the wood species, timber density, screw dimensions, thread configuration, installation method, and application conditions.

Type 17 Wood Screw Size & Material Range

The available material and size range is based on the current SANN MUO Type 17 product specification. Final screw configuration can be developed according to the customer's application and technical requirements.

Material Options for Different Wood Screw Applications

SANN MUO offers Type 17 Wood Screws in different steel and stainless steel materials to accommodate different applications.

Stainless Steel 304

Suitable for applications requiring stainless steel construction and improved corrosion resistance compared with standard carbon steel.

Stainless Steel 316

A higher corrosion-resistance option for applications exposed to more demanding environments.

Stainless Steel 410

Suitable for applications where a martensitic stainless steel grade is required.

Carbon Steel 1018 / 1022

Suitable for general-purpose wood screw applications where carbon steel is appropriate.

Alloy Steel 10B21 / 10B33

Available for applications requiring alloy steel material.

Material selection should be based on the wood type, environmental exposure, required mechanical performance, surface treatment, and application conditions.

Customized Type 17 Wood Screws

Not every timber application requires the same screw configuration.

SANN MUO can develop and manufacture Type 17 Wood Screws according to customer drawings, samples, technical specifications, and actual installation conditions.

Customization can include:

• Screw diameter
• Screw length
• Type 17 point geometry
• Thread configuration
• High-Low Thread
• Head design
• Material
• Surface treatment
• Drive type
• Packaging
• Customer-specific specifications

Our R&D and product development process can be based on the actual conditions of on-site use, allowing the screw design to be optimized for the required application performance.

Choosing the Right Type 17 Wood Screw

When selecting a Type 17 Wood Screw, several factors should be considered.

1. Timber Type

Different wood species have different densities and fiber structures. Screw geometry should be selected according to the timber being fastened.

2. Timber Thickness

Screw diameter and length should be selected according to the thickness of the timber components and required thread engagement.

3. Installation Location

When fastening close to an edge, a Type 17 cutting point can help reduce the tendency of the timber to split.

4. Required Holding Strength

Applications requiring increased grip can be considered with a High-Low Thread configuration.

5. Environmental Conditions

For outdoor or corrosive environments, stainless steel or an appropriate surface treatment may be considered.

6. Installation Method

Driver type, installation speed, torque, and pilot-hole conditions can all affect final fastening performance.

Frequently Asked Questions

Q. What is a Type 17 Wood Screw?

A Type 17 Wood Screw is a wood screw featuring a specialized cutting point with grooves designed to cut wood fibers and help remove sawdust during installation.

Q. What does the Type 17 point do?

The Type 17 point cuts timber fibers into smaller pieces and helps collect and remove sawdust. This can reduce the tendency of timber to crack or split during screw installation.

Q. Do Type 17 screws prevent wood from splitting?

The Type 17 point is designed to reduce the likelihood of timber splitting and cracking, particularly during installation. Actual performance depends on the wood species, screw size, installation conditions, and application.

Q. Why use a Type 17 screw near the edge of wood?

Fastening close to an edge can increase the risk of timber splitting. The Type 17 cutting point helps cut the wood fibers rather than simply displacing them, making it suitable for applications where reduced splitting is important.

Q. What is a High-Low Thread?

A High-Low Thread uses two different thread heights. The high thread cuts deeper into the wood, while the low thread increases contact with the substrate.

This configuration helps produce stronger grip and improves resistance to pull-out and vibration loosening.

Q. What is the difference between a Type 17 point and a regular wood screw point?

A Type 17 point incorporates cutting grooves specifically designed to assist with cutting wood fibers and removing sawdust. A conventional wood screw point may not have the same cutting-groove configuration.

Q. Can Type 17 screws be used for decking?

Yes. Type 17 screws can be used for selected decking applications where efficient penetration and reduced timber splitting are important.
