Wood Screws (DIN 571, TTQS, Chipboard Screws)
Wood screws are specifically designed to ensure solid and secure fastening in wood-based materials, with optimized threading for effective penetration and a firm grip. They are mainly used in carpentry, construction, and furniture manufacturing, offering solutions for all kinds of woodwork.
Features and Benefits:
- DIN 571: Deep thread for strong grip, even in softer woods.
- Wide variety of options for different applications.
- Easy to screw in thanks to sharp points, reducing the risk of wood splitting.
Main standards:
- DIN 571: Hex head wood screws, ideal for strong wood-to-wood and wood-to-metal fixings. Perfect for structural and heavy-duty carpentry applications.
- DIN 603: Round head screws with square nut under the head (TTQS), used for decorative assemblies requiring high stability, such as furniture or wooden structures.
- Chipboard screws: Designed for chipboard and softwoods, with deep threads for excellent grip. Used in furniture and window/door manufacturing.
Types:
DIN 571 – Hex Head Wood Screws
DIN 571 screws, also known as hex head wood screws, are robust and versatile fasteners, designed to ensure a strong hold in wood, masonry, and mixed materials. With partial threading and hex head, they can be tightened precisely using wrenches or power tools, ensuring a stable connection even under significant stress.
Available in white zinc-plated steel and A2/A4 stainless steel, DIN 571 screws offer excellent corrosion resistance and are suitable for both indoor and outdoor use.
- Ideal for wooden structures, light carpentry, and anchor fixings
- Hex head for secure and controlled tightening
- Available in white zinc and stainless steel for humid or corrosive environments
- Deep threads ensure excellent grip in natural materials
- Suitable for use in construction, plant engineering, roofing, and prefabricated elements
Thanks to their strength and ease of installation, DIN 571 screws are a reliable and long-lasting solution for a wide range of applications.

DIN 603 – UNI 5731 Round Head Bolt with Square Neck
Round head bolts with square neck (UNI 5731 / DIN 603) are designed to offer secure and tamper-resistant fastening, thanks to their smooth round head and square neck that prevents rotation during tightening. They are especially recommended for metal carpentry, wooden structures, fences, frames, and industrial applications where stable fastening and a clean, unobtrusive appearance are required.
These bolts are generally used in combination with hex nuts and washers, and are ideal in contexts where external tool access must be limited, as the smooth head has no drive recess.
- Square neck prevents rotation during tightening
- Smooth round head for clean finish and tamper resistance
- Ideal for carpentry, wooden structures, and decorative or functional assemblies
- Available in zinc-plated steel and, upon request, in stainless steel
- Compatible with standard nuts and washers, also for through-hole fixings
Chipboard Screws for Wood
Chipboard screws in carbon steel are designed to ensure excellent penetration and grip in wood-based materials like chipboard, MDF, and plywood.
Available in several protective finishes—white, yellow, black zinc-plated, and nickel-plated—they offer versatile solutions for the furniture industry, carpentry, and industrial assembly. Their deep threading and high-quality steel ensure quick engagement, load resistance, and long-lasting performance, even in the most demanding applications.
