Threaded studs

The threaded stud was originally designed for mechanical engineering — to join smooth machine components when no other fastening solution was available. Over time this versatile fastener also found its way into construction. Today it is one of the most widely used types of fasteners: it is applied in mechanical engineering, construction, the installation of ventilation systems, advertising structures and other tasks.

Features of threaded studs

Products are manufactured to GOST, DIN and ISO standards.

A threaded stud can be used to extend fastening structures with a metric thread, as well as to join wooden elements — boards, timber, joists. For installation, a collet is fitted into one of the elements being joined, trimmed to the required size if needed, and used to secure material of a given thickness within the permissible load limits.

The fastener is used in construction and mechanical engineering for installation work requiring reliable fixation of elements spaced apart from each other.

Studs are made from strong metals and alloys capable of withstanding intensive and prolonged mechanical loads. The products are often zinc-plated — this protects them from moisture and temperature fluctuations, and gives them a grey-silver color.

Studs differ in length, diameter, thread pitch and the method of thread application. The choice of a specific product depends on the installation/assembly task and the nuts used.

Fixing is done with nuts, anchors, welding or screwing into a prepared hole. Washers are additionally used — they ensure a reliable connection between dissimilar materials and resistance to vibration loads.

Studs are produced with medium and increased strength properties — the property class is selected based on the required durability and the load on the structure.

A threaded stud is a long rod (from one to three meters) with a metric thread along its entire length. Despite its simple design, it is used in a wide range of jobs, especially in construction.

This type of fastener is indispensable where the components or structures to be joined are spaced at a distance that cannot be covered even by the longest bolt. Areas of application:

• installation of suspended ceilings, cable trunking, ventilation and heating systems
• construction of frame houses
• making formwork for monolithic concrete house construction
• installation of advertising billboards
• joining timber, joists and boards when laying wooden floors

Nuts, washers, connecting sleeves, drop-in anchors or perforated metal profile are used to connect with the threaded element.

The product is also used as a hanger and, if needed, is cut into sections of the required length.

One of the common standards is DIN 975. Today this standard has been replaced by DIN 976-1, “Zinc-plated, threaded, stainless studs, metric, with metric thread, diameter from M2 to M42, length 1000, 2000 and 3000 mm.” Under DIN 975, studs are made of carbon steel of property class 4.8 or 8.8 with subsequent zinc plating. For aggressive environments — salt water or liquids with increased acidity — stainless steel is used, since zinc-plated steel cannot withstand such operating conditions.

Before selecting a fastener, the diameter and length of the product should be calculated, and the property class determined taking into account the load and operating conditions. This ensures the reliability and durability of the connection.
