Standard Pan Head Chipboard Screw 3.5x45 mm Pack of 500

Standard Countersunk Chipboard Screw (3.5x45 mm):

Fine Work and Long Hold Balance

Flat Head (Countersunk Head) chipboard screws combine precision and reliability in carpentry and furniture manufacturing. This specific 3.5x45 mm size minimizes the risk of cracking with its thin diameter and provides a deep and strong hold with its 45 mm length. This combination is ideal for delicate applications that require thin yet deep fastening.

User Information and Target Audience

This product appeals to professional and amateur users who prioritize precision and aesthetics:

Precision Furniture Manufacturers: Preferred by craftsmen working with veneer, lacquer, or thin and valuable panels. The 3.5 mm diameter prevents surface tension and cracking that larger screws might cause, while the 45 mm length provides sufficient depth in thick panels.

Renovation and Decoration Specialists: Used for deep fastening of relatively thin decorative elements such as architraves, moldings, skirting boards, or paneling to a wall or a thick frame.

Small Project and Hobby (DIY) Users: An excellent choice for users looking for both a strong and aesthetic result when joining medium-thickness wood materials.

The pack of 500 is a standard and economical solution for both professional workshops and avid hobby users.

Areas of Use and Applications

The 3.5x45 mm screw meets the need for deep fastening with the advantage offered by its thin diameter:

Important Note: The 3.5 mm diameter ensures that the screw occupies less volume when entering the material, which reduces the risk of cracking, especially near edges or in high-density materials, allowing for cleaner workmanship.

Sectors Used In

This screw plays an important role in sectors where high-quality and careful workmanship are paramount:

Custom Design Furniture: In boutique furniture and interior design projects where high aesthetic expectations and expensive materials are used.

Interior Decoration and Renovation: For the assembly and finishing of thin, visible wooden elements.

Mass Furniture Production: A standard intermediate size that provides flexibility in joining panels of different thicknesses.

Material Properties and Technical Details

The technical design of the 3.5x45 mm chipboard screw combines the strength required for deep penetration with the precision provided by its thin diameter:

1. Material Structure

Material: Hardened carbon steel (C1022) is typically used. This hardening allows the screw, at a length of 45 mm, to penetrate deeply into the material without bending or breaking.

Coating: Yellow or white zinc plating (galvanized) is common, which is sufficient for indoor conditions. Yellow plating often offers better visual distinction or a slight advantage in rust resistance.

2. Design Features

Head Type (YHB): Flat Countersunk Head. Its conical shape ensures that the screw sits flush in the hole on the surface, becoming level with the material. This is critical for an aesthetic appearance after assembly.

Thread Structure: Features widely spaced and sharp threads optimized to create high holding power in wood-based materials such as chipboard and MDF.

Tip Structure: Has a sharp, pointed tip for easy and quick insertion. Its thin diameter results in low resistance when entering the material.

Drive Type: Commonly uses Pozidriv (PZ) or Phillips (PH) drive types, which are widely used and reduce cam-out during assembly. For 3.5 mm diameter, PZ1 or PZ2 bits are generally recommended.

This screw is an indispensable product for carpenters, combining the advantage of precise and clean workmanship provided by its small diameter with the deep and reliable fastening power offered by its 45 mm length.
