Wood screws

Wood screws are a fastener in the form of a rod with a head and an external thread that forms an internal thread in the hole of the parts being joined. They are used in construction, furniture manufacturing, and repair and construction work. FLOK supplies wood screws wholesale and retail.

Wood screws and self-tapping screws are the most in-demand fasteners in manufacturing and everyday use. Both types of hardware are metal rods with an external thread and a slotted head. Wood screws are driven in by hand (with a flat or Phillips screwdriver), with a drill, or with a power screwdriver. The thread is cut into the material by the sharp tip and the profiled surface of the screw. The fasteners are made of tool carbon steel grades U7–U9, brass, or stainless steel.

Applications

Wood screws are used in construction, finishing work, appliance repair, and furniture assembly. Small threaded fasteners are driven into wooden, plastic, and drywall products, and thin sheet metal. Paired with wall plugs, wood screws are used to attach suspended elements to brick and concrete walls and ceilings.

Selection tips

Wood screws are selected depending on the material of the parts being joined.

• Metal up to 2 mm. Special self-tapping screws with a fine-pitch double-start thread and a sharp-angle profile are needed.
• Wood, chipboard, MDF, plastic, drywall. Fasteners with a large thread helix angle, wide pitch, and a sharp tip are preferred.
• Metal roofing tiles, profiled sheet. Roofing work is done with self-tapping screws having a washer-shaped head and a rubber seal.
• Drywall, plastic. Fastened with self-tapping screws with a countersunk (conical) head that sinks into the base material.

FLOK offers wood screws for various surface types: concrete, wood, plastic, roofing, as well as universal screws for any construction base.

A wood screw is a type of fastener for household use, professional construction, and furniture manufacturing. Structurally, it is a metal rod with a threaded tip at one end and a slotted head at the other. The thread of a wood screw is less sharp than that of a self-tapping screw. The thread may run along the entire body or end at about 2/3 of the length, with no thread under the head. A wood screw is driven into a prepared hole with a flat or Phillips screwdriver.

Wood screws are driven in with a drill into soft materials or into metal. Fasteners for metal have a finer thread pitch than fasteners for wooden surfaces.

This type of fastener joins soft materials, typically wood. It is used together with wall plugs for installing and securing lightweight structures on walls and ceiling slabs.

The head of a wood screw can have different shapes:

• hex,
• cylinder,
• countersunk,
• round (button).

The tip of a wood screw can be of various types. This fastener is used to join parts, assemblies, and structures in machine building and construction. Unlike a screw, a wood screw has a self-tapping thread, usually self-locking. According to GOST, wood screws are defined as threaded products for plastic and wooden structures.

A variant of wood screws is self-tapping screws, which do not require pre-drilling. They come with various head types: countersunk, raised countersunk, hemispherical, hex, and the tip is either drill-point or sharp-pointed. The thread on self-tapping screws varies in pitch and is applied at different angles. They are made of hardened tempered steel. For corrosion protection, the products are coated with zinc, phosphates, and oxides. The heads have deep cross-recess slots for the driving tool.

Self-tapping screws easily screw into metal up to 2 mm thick thanks to the sharp tip, which acts like a drill bit, and have a fine or double-start thread. For soft bases, self-tapping screws with a wide thread pitch, a sharp tip, and a large thread helix angle are suitable.

Roofing work requires self-tapping screws with a washer-shaped head and rubber gaskets for sealing; the fastener is coated on top with paint matching the roof color.

Self-tapping screws with a countersunk head are one of the most popular variants of this fastener. The countersunk head transitions smoothly into the shaft. These products are used for installing lightweight structures made of drywall or plastic.

A hex head on a self-tapping screw increases its strength and is used together with a plastic wall plug for fastening heavy structures.

Characteristics

1. Fasten to wood surfaces, plastic, and metal bases.
2. Suitable for outdoor and indoor work.
3. Screw into wood and can be used as clamps to join two parts.
4. Easily removed when needed, which is important for restoration and repair work.
5. Fast installation: thanks to the sharp tip, they easily penetrate wood surfaces without drilling a pilot hole.
6. Stronger than nails — they withstand greater loads, including strong wind gusts and shifting of the joined surfaces.
7. Higher tensile strength than nails, which can break or bend.
8. Resistant to rust and precipitation.
9. The variety of the product line makes them a versatile type of fastener for repair and construction work, furniture manufacturing, and construction.

The FLOK wood screw catalogue includes the following range:

• Roofing self-tapping screws are used in roofing for cottage construction to fasten to wooden battens. They withstand loads from wind and snow cover. Made of carbon steel.
• Wood screws DIN 7995 and 7996 are used in construction, household applications, and furniture manufacturing. The coating provides corrosion resistance.
• Wood screw DIN 96 with a medium-pitch external thread and a spear-shaped sharp tip. Used by builders, repair crews, and furniture makers.
• Wood screw DIN 95, 97 for wooden furniture structures. Made to German standards, moisture-resistant, and durable.
• Flugel drill-point wood screw with ribs that act like cutters: it drills, countersinks, and clamps in a single pass. Used for joining wood and plywood panels, it withstands moisture well. Treated with electro-galvanizing, yellow passivation, and other coatings.
• An L-hook wood screw is used in households, retail, and offices. It can be installed in any surface; in soft wood surfaces it requires no pre-drilled hole and can be driven in without a tool, for example using a handle bent at 90°. A wall plug is used for concrete surfaces.
• DIN 96 wood screw is made to German standards. It drives in quickly, forming a reliable joint.
• DIN 571 wood screw for timber, complies with German fastener standards.
• Furniture screw-bolt for assembling case and modular furniture, available in many variants.
• Norfi screw-bolt for hose clamps is used in the automotive industry and technical sectors — for fastening hose connections in internal combustion engines, refrigeration equipment, and household and industrial devices.
• Hook screw is used to fasten various elements (clothesline or wire).
• An eyelet screw for concrete or wood is driven into different surfaces; the eyelet serves as a hook for securing.
• Universal self-tapping wood screw is used in machine building, instrument engineering, aviation, electronics, and other industries.
• Facade screw is used for construction and repair work, fastening facades, and advertising structures.
• Furniture tie screw made of high-quality coated steel.
• Self-tapping wood screw is a universal fastener with full or partial thread, and a flat or countersunk head. Made of chromated steel coated with zinc or Teflon.
• DIN 571 wood screw does not require additional drilling, securely joins structures, and is used in construction. A nut runner can be used for driving it in.
• Furniture wood screw is used in furniture manufacturing and may be coated with paint. Most often made of steel alloys.
• Screw-bolt is a tapered rod with thread at the end and a spherical or countersunk head with a slot or cross recess. Used for joints that can later be disassembled.
• Wood screws do not require pre-preparation of a hole — they create it as they are driven in. The resulting joint is stronger than gluing or nailing, and can join materials of different types. They come with several head types.
• Self-tapping wood screws are used for securely joining two parts in nearly all areas of production — from furniture to space technology.
• Wall plug screw anchor is used for fastening structures together with self-tapping screws or wood screws matching in length and diameter. There are through-type and pre-set types.
