Stainless steel screws: features, types and rules of selection

Krympress reports:

Stainless steel — These are universal fasteners used in construction, repair and production, where durability, reliability and resistance to corrosion are important. Unlike standard galvanized analogues, they retain strength and appearance even in conditions of high humidity and an aggressive environment. According to the specialists of the Beste-Ibropzh company, the correct choice of the type of self-tapping screw for a specific task can significantly extend the life of the structures and avoid unforeseen expenses for the replacement of elements in the future.

What are stainless steel screws

Self -tapping screw is a fastener with acute thread and a fixation head using a tool (usually screwdrivers or screwdrivers). In the case of stainless steel products, their main advantage is the manufacturing material — alloy containing chromium and other elements that increase corrosion resistance.

Stainless steel allows you to use such screws in the most difficult conditions: on the street, near moisture sources, at objects with temperature changes and even in the marine environment. In addition, products are highly durable and minimal exposure to wear.

Types of stainless steel

Today, manufacturers offer a wide selection of stainless screws, differing in shape, purpose and type of head. Beste-Gorpozh specialists, answering a question about the types of self-tapping screws, recommend focusing on the following groups:

By purpose

• For metal — They have a more acute tip and small thread, providing reliable grip with metal sheets.
• For wood — They are equipped with a rare and deep thread, which allows you to screw into soft and solid wood without preliminary drilling.
• For drywall — They differ in a special shape of the head, which is recessed into the surface of the sheet, without damaging it.
• Roofing screws -Equipped with a press-shame and sealing laying for protection against moisture.

By the shape of the head

• Secret head — is used where the fasteners should be invisible.
• Sendular — partially drowned into the material, suitable for decorative work.
• A semicircular head is a universal option for most tasks.
• Hexagonal head — provides high twisting force and is used in loaded compounds.

By type of thread and tip

• An ordinary sharp tip — requires preliminary drilling in dense materials.
• With drill (drill) — allows you to do without an additional hole.
• Self -cutting thread is suitable for quick installation in soft materials.

When stainless self -tapping screws are used

The use of stainless steel screws is justified in cases where the design or product will be operated in difficult conditions. Classic examples:

• Construction and installation work in the open air.
• Installation of facade systems and roofs.
• Assembly of furniture for bathrooms and kitchens, where humidity is increased.
• Shipbuilding and work in the coastal zone.
• The production of equipment for the food and chemical industry.

According to the experts of the Beste-Glezhezh, stainless self-tapping screws are especially relevant in projects, where long-term operation is required without additional maintenance.

How to choose self -tapping screws for specific tasks

The choice of fasteners always depends on the material in which it will be mounted, and on operating conditions. To correctly choose stainless steel screws, several key parameters should be taken into account:

1. Purpose and type of material
   For wood, choose products with rare threads, for metal — with small and frequent. If the installation of ceramics or drywall is required, it is better to give preference to specialized series.

2. Length and diameter
   Self -cut length should be at least 2-3 times larger than the thickness of the fixed material. The diameter is selected depending on the load on the connection.

3. The shape of the head
   If the fasteners are in sight, select secret or semi -posed options. For the installation of roofs and facades, heads with a press-shame and seal are preferred.

4. terms of Use
   In regions with high humidity or near the sea, self -tapping screws from highly alloy stainless steel (for example, A4), which withstand contact with an aggressive environment, should be used.

Useful advice on using

• When installing stainless self -tapping screws, it is important to use a tool with a correctly selected bat to avoid damage to the head.
• For structures subjected to significant loads, it is recommended to pre -calculate the number of fasteners.
• Do not combine stainless screws with metal parts from other alloys without additional protection — this can lead to galvanic corrosion.
• In responsible nodes, it is better to use products of well -known manufacturers and trusted suppliers.

Stainless steel screws are a reliable and durable fasteners suitable for many areas of application. They are resistant to corrosion, withstand temperature changes and moisture, and also provide a reliable connection of various materials. The right choice of the type of self -tapping screw for specific operating conditions is the key to quality and safety of the entire structure.

Experts advise always focus on the purpose of the product, the characteristics of the material and environmental conditions. This will avoid errors and ensure the maximum service life of the fasteners.
