Hexagon Flange Head Tapping Screw Thread Type-23

Product Background and Definition

Hexagonal Flange Head Self-Tapping Screw (Type 23 Thread) is a screw designed specifically for soft metals and plastics, featuring a Type 23 thread-cutting design. According to online professional information, Type 23 thread-cutting screws are commonly used for soft metal castings such as zinc and aluminum, as well as plastic parts that require standard machine threads. The wide cutting groove of this screw facilitates chip removal and low torque during installation, making it suitable for efficient assembly.

Product Features

Head Type Design: The hexagonal head is equipped with a flange for easy tightening with a hexagonal wrench. The flange acts like a washer, increasing load distribution and preventing the screw from sinking into the material. This design is particularly suitable for applications that require high stability.
Type 23 Point Type: With a blunt point and wide cutting groove, it has high cutting efficiency and is suitable for cutting soft materials. Type 23 screws are similar to Type F screws, but the cutting groove is wider and deeper, suitable for materials that produce more chips.
Thread Type: It adopts machine thread, which is compatible with standard nuts and pre-drilled holes, providing flexible assembly options.

Specifications and Materials

Based on common industry standards, assume the following specifications for this product:

Material: Steel, common in Type 23 screws, heat-hardened for strength
Surface treatment: Galvanized for enhanced corrosion resistance, suitable for indoor and outdoor environments.

Application Scenarios

Type 23 screws are particularly suitable for the following scenarios:

Assembly of metal castings, such as aluminum and zinc parts, which are widely used in industrial manufacturing.
Fastening of plastic components, especially in plastic products that require standard machine threads.
Electrical and electronic equipment, which require secure fastening on soft metals.

Type 23 screws perform well in cast iron and certain plastics, and are suitable for applications that require cutting threads.

Comparison with other types of screws

Comparison with Type F screws: Type 23 screws have a wider cutting groove, suitable for materials that produce more chips, while Type F screws have a narrower cutting groove, suitable for thinner metals.
Comparison with Formed Screws: Type 23 screws create threads by cutting, while formed screws form threads by material displacement. The former is suitable for harder materials, while the latter is more suitable for plastics and reduces the risk of material breakage.

Installation and Usage Recommendations

Installation Tools: Use a hexagonal wrench that matches the head shape to ensure uniform tightening force.
Installation Tips: Confirm that the material is suitable for cutting before installation to avoid damage to the screws caused by too hard materials. Apply moderate pressure to prevent thread stripping.
Storage Recommendations: Galvanized surfaces should be avoided from long-term exposure to humid environments to maintain corrosion resistance.

Certifications and Standards

This product meets the industry’s common thread cutting screw standards and is available in different sizes and material versions upon request. Detailed standards can be referred to relevant industry specifications, such as ISO or DIN standards, but specific certifications depend on the manufacturer.

FAQs

The following are questions that potential users may be concerned about:

**What is a Type 23 screw? **
Type 23 screws are cutting screws designed for soft metals and plastics, with machine threads and wide cutouts for easy chip removal.
**Can they be used on wood? **
While possible, the Type 23 is designed primarily for soft metals and plastics, and wood is better suited to specialized wood screws or Type 17 cutting screws.
**What tools are needed for installation? **
A hex wrench that matches the hex head is required.
