Use of bolts in construction

Bolts are machine elements with an extensive applicability. They are used in the automotive, aviation, and electrical industries, in the production of furniture, elevators, wagons, shocks suspenders, etc. For the bolt to be truly safe, it must be thoroughly tested, specifically in response to:

  • shear stress
  • bending stress
  • surface pressure between bolt and bar or bolt and casing

At Zakrajšek d.o.o., we produce a variety of bolts; their desired use determines the shape, size and material. We offer the following bolts:

Bolt dimensions and materials

Dimensions and materials

We produce bolts with a diameter from Ø 0.6 to Ø 7 mm and a length of up to 75 mm. They are made from various materials that usually determine their intended use. We offer bolts made from brass (CuZn), aluminum-magnesium (AlMg), iron (Fe), copper (Cu), aluminum (Al), stainless steel – inox (Rf), and silver (Ag). The price depends on the size, shape and material. All bolts are made to order, taking into account all the customer’s wishes.

 

Bolts connect parts in the two following ways:

  • both parts are mobile on the bolt
  • one of the parts is fixed and immobile on the bolt

The mobile part must always be attached loosely and greased, with a bearing sleeve inserted. The immobile part must be fixed with a strong bond.
