Material Introduction

The common materials for Slotted round head wood screw DIN 96 mainly include carbon steel, stainless steel and copper alloy. The specific type of material to be chosen depends on the usage environment, strength requirements and cost budget.

（1）Carbon Steel

Carbon steel is the most commonly used material for wood screws, featuring low cost, high strength, and good processing performance. Among them, low-carbon steel is the most common type, as it has a low carbon content, better toughness and processing performance, and is suitable for cold heading forming.

（2）Stainless Steel

The surface naturally forms a dense oxide film, providing excellent corrosion resistance protection. No additional surface treatment is required and it is suitable for most humid environments and outdoor applications.

（3）Brass / Copper Alloy

Copper alloy Slotted round head wood screw DIN 96 (commonly made of brass) are often used in special decorative or functional settings due to their natural golden appearance, excellent corrosion resistance and conductivity.

Material	Characteristics	Applicable Scenarios
Brass, CuZn	The appearance is beautiful and golden in color. It has good corrosion resistance, but its strength is lower than that of carbon steel.	High-end furniture, antique restoration, art installations, decorative hardware accessories, electrical connections
Bronze	Its corrosion resistance is superior to that of brass, and its appearance is a darker brown color.	Vessels, outdoor decorations, sculpture fixation

FAQ

（1）Will carbon steel Slotted round head wood screw DIN 96 rust during maritime transportation?

To reduce the risk of moisture-induced rust during transportation, we usually adopt protective measures such as VCI rust prevention paper + plastic bag sealing + desiccant, which can effectively prevent rust.

（2）How to evaluate the corrosion resistance of DIN 96 screws?

Corrosion resistance is assessed through salt spray tests. Carbon steel galvanized screws can typically withstand 48-100 hours; stainless steel screws can withstand hundreds to thousands of hours without rusting.

（3）What should the installation torque be?

The torque depends on the material, type of wood and lubrication conditions. For example, when a 4 mm carbon steel Slotted round head wood screw DIN 96 is driven into hard wood, the recommended torque is approximately 2–3 N·m. Exceeding this value may cause the slot to slip or the head to break.
