DIN 25193 Mushroom-Head Anchor Bolt

Anchor bolts are a class of fasteners for installation into solid base materials and for securing construction materials and profiles. The anchor is fixed in the material through friction and the material’s resistance to fracture; chemical anchors are also used. These fasteners are designed for heavy and large-sized items.

Design and application features

Types of anchor bolts:

• With a nut and expansion element. When screwed into the material, this element enters the expansion sleeve, providing a secure fixation.
• With a hook. The same design, supplemented with a hook for attaching suspended structures.
• With a ring or half-ring — for attaching structures to walls and floor/ceiling slabs.
• Double-expansion. Two expansion sleeves for a more reliable connection with the material.

Anchor bolts are used in construction for fixation in dense materials, including concrete and brick walls. Certain anchor types are suitable for installation in hollow materials — aerated concrete and foam concrete.
